There was a thing that was around 10 or 11 years ago called "Wireless USB", and it was actually kind of cool. It did exactly what it sounds like, you could plug in two different arbitrary USB devices into hubs or a computer that supported wireless USB, and the computer would just recognize it as a vanilla USB device. I don't actually know why it never caught on, I thought it was neat, and it seemed to work fine. I guess due to the popularity and ubiquity of bluetooth?
Video is worth a watch although it also doesn’t give an answer for why Wireless USB actually disappeared.
I was wondering after watching that video, if it could be due to security concerns? Like, is the Wireless USB protocol encrypted? And if so, does it use sufficiently strong encryption?
I did find a document that talks a bit about Wireless USB encryption.
I actually saw that video, but I had heard of Wireless USB for awhile. My manager at my first job after dropping out of college the first time got it for his computer and he was super excited.
At least according to Wikipedia, it was encrypted.
There's "encrypted", and there's encrypted. WEP for wifi was encryption, but cracking it was so trivial that for some years it was practical to crack yourself access to wifi wherever you were on a casual whim.
Still, even if the encryption was very weak, wireless wifi sounds appealing to me, at least for my old trusty wired mouse. Somebody snooping on or spoofing my mouse seems like an academic threat.
No, definitely not. The intersection of people who would think to do that, have the skill for it, and the inclination to view me personally as their target is probably zero.
Not to mention that I don't think anyone but a few niche enthusiasts even have the hardware to do it even if they had the skills and inclination. Who's going to walk around with a 15 year old laptop brute-forcing wireless USB encryption, or find some obscure hub and do it on a modern laptop?
I'm not going to say the likelihood is "zero", but I am going to say it's so close to zero that it's really not worth even considering.
I inadvertently pranked myself like this. For a while my laptop got super haunted, occasionally the cursor would jiggle slightly even when I wasn’t touching the mouse. Eventually I realised that the Bluetooth mouse in my bag which I’d totally forgotten about was getting bumped and turning on.
It was a very limited implementation of wireless USB. You could only plug in two USB devices and only particular devices worked, if I remember correctly. My suspicion is that the reason it went off the market was because it used UWB and the government put a lot of restrictions on its use so that it couldn't be repurposed for use in military applications. It's very difficult to intercept an encrypted UWB communication link, or to even know it is present. It essentially just looks like a slight raising of the noise floor across a wide band of frequencies. UWB was required to get the necessary bandwidth, doing USB across WiFi would probably cause timing errors in devices because it would be so slow (at least using 802.11b which was in wide use at the time). I think hardware makers really hated the idea also because a successful wireless USB system would allow sharing hardware between many computers instead of buying a device per computer (consumer NAS was expensive back then). It was also very expensive, about $400 I think, which was a lot at the time for something that had limited functionality. I remember thinking about buying one and decided it wasn't worth it.
I remember actually testing that stuff out when it came out. I was working as an intern at Philips Semiconductors in their Wi-Fi chip division. Speaking of time has no meaning... :)
I think there were a couple of consumer products that got released - Linksys and netgear perhaps? They consisted of a USB Hub + Dongle.
They actually worked ok, but the speed would drop off quickly with distance. Across the room, and you'd be at 50% of the rated speed, at best.
The technology was interesting. Basically they were transmitting over a whole slew of spectrum simultaneously (from like 2.5GHz to 5.5GHz), but they kept the transmit power low enough that it didn't exceed some FCC threshold.
Does that mean they’ll work with any wireless USB adapter? I have a 360 controller but haven’t been able to source a USB dongle to use it with my computer.
Interesting that you can't find one. I got one a few years ago when I built a little emulator system out of a Pi. Works fine. I can't remember where I got it, though. I thought eBay, but I don't see it in my purchase history.
I recently found out that a manufacturer (TI, NXP, murata, infineon?) was demonstrating a USB2 live camera capture using a UWB (Ultra-Wide-Band) short range wireless transmission. But I can't found the source again.
When Mac first took out the DVD drive, there was also a away to mount remote DVD drive. I guess the push was to get everyone on the network. So stuff like that just didn't take off.
I'm running virtualhere on thousands of raspberry pi's sharing various USB devices to cloud machines over vpn. It's been working without issues for years now. Seems to be a solo developer in Australia that's been working on it for a really long time. https://www.virtualhere.com/
Thanks for your work. I tried using it to use the official Gamecube Controller USB Adapter through Steam Link, but there was some spiking noise that killed playability. Nevertheless, I think it is amazing stuff.
This sounds like a cool use case for my observatory control box. Do you ever have issues with latency pushing the bounds of the USB spec wrt latency? Can I use this with my camera?
I have a lot of astro users. But you need to use Ethernet for the connection between VirtualHere server and client and not wifi. A pi5 is very good for this.
The reality is that licenses must be restricted because people cheat, steal and pirate. Hate them instead. Besides $49 is dirt-cheap for what it is, especially considering it covers all future versions.
> This USB server solution is perfect for allowing USB devices to be used remotely over a LAN network, over the Internet, or in the Cloud without the USB device needing to be physically attached to remote client machine.
> Possibly because a developer hired to write something around usbip would cost a lot less. https://usbip.sourceforge.net/
Would it? For the sake of discussion, I'll assume "thousands of raspberry pi's" = 2,000 RBpis, or something around $10,000 in license fees.
I don't know anything about either project beyond the links shared by you and the root comment, but based on the information at each link and the assumption of $10,000 spend:
I would choose the one time cost of VirtualHere's purpetual update license and release cadence over a some short dev for hire contract to write some unmaintained wrapper code around a sourceforge library that hasn't been been touched in over a decade.
$49 times 2,000 is $98,000, not around $10,000. Yet your argument still holds. There are many reasons for that.
1. You are paying a developer that works 100% on that, year after year, and not a hire that won't be there when something goes wrong in the future after an OS update, new hardware, anything. This is basically your argument. Let me add:
2. In some parts of the world far away from SV but still in the West, $100k are about two years of gross developer salary, not what the developer actually gets at the end of the month. Point 1 still holds. Where it's 10 years of salary maybe companies could be tempted by a custom solution.
3. You are giving $49 per server to that developer but you are probably getting more per server from your customers. If you have thousands of servers you probably have a viable business, so that's just yet another cost of doing business.
usbip has made me angry for 5 years now, there is supposedly an open source windows client, but you have to put windows into some unsafe bullshit mode to be able to use unsigned drivers??
So you have to compromise your entire system to use one program
I mean you could sign it yourself. Or donate to a maintainer so they can sign it. Open source or other community windows drivers usually aren’t signed unless they have donors paying for it, certs aren’t free :)
If anything it’s on windows for not having a way to allow just one unsigned driver.
The one hack I keep hoping <someoneelse> will do the actual work for is -
redirecting my steamdeck control via usb to my linux gaming rig and expose it as a usb device(s) for steaminput.
It seems like a natural and perhaps even "straightforward" hack but I've seen no evidence of one so far, perhaps there is something in usb that limits the ability to proxy it correctly.
This looks closer then anything I've seen so far, thanks!
From what I can discern its missing important bits of the controller and doesn't have any steaminput profile etc so it's clunky still.
Worth poking at though.
edit - to clarify, ideally steaminput would be tricked on the host to think that it "was" a steamdeck so all the mapping features would be available. I don't really need another usb game controller its more the steamdeck touchpad etc.
I didn't watch those youtube videos, but the text links either agree with the opinion that bluetooth is worse, or don't refute it.
That rtings graph shows that bluetooth is pretty clearly worse in the majority of cases from wired or wireless (which is distinct from bluetooth).
"Bluetooth" doesn't appear anywhere on that Reddit thread.
And from the second rtings:
> The mouse's connection type affects the click latency. Generally, wired mice have the lowest latency, and Bluetooth mice have the highest latency. A Bluetooth connection isn't recommended for gaming, but it's still good for office use, and most people won't notice any delay unless the latency is extremely high.
If you look at the graph again, not all of them are worse, which means it's obviously possible to make it on par or close to it. But regardless, the complaint was "too much latency for many games", which is not the same as "worse". And I don't think this amount of latency is too much for the vast majority of games.
Few/none of the wireless gaming mice are using bluetooth, its proprietary radio protocols and usb dongles.
Click latency is not too useful vs swipe latency.
Bluetooth has a pretty low polling rate iirc and that kills the swipe latency.
More generally and responsive to what we were talking about, proprietary radios are not bluetooth and they are not WiFi which is the latency we are actually talking about (which is usable but not for me to play elden ring by direct experience).
VirtualHere will run over any network connection, that user just happened to use wifi.
All the mice I am aware of that use Bluetooth are travel mice and the like. Even cheap gaming mice use RF dongles that do not have the Bluetooth polling limitations.
You can tell your friends in Fortnite you died because of mouse latency, but lets keep HN discussions grounded in reality please.
Maybe allow mounting of the the steamdeck input devices in steamdeck:/dev over network on your linux box so it is exposed as an additional device? Something like plan9 does.
Valve's "remote play" allows one to play games on another host computer via your Steam Deck as though you are plugged straight. If you don't need the video streaming, you can lower the settings.
edit; oh nm, user wants a direct wired connection to work.
I'm on my phone so I can only do so much digging, but from the usbip sourceforge page that's linked above, it says that development has moved into the Linux kernel:
For Linux, the source code of usbip was merged into the staging tree, and finally has been moved to the mainline since Linux-3.17. Development is ongoing in the kernel community, not here. Linux distributions will provide binary packages of usbip.*
Probably... I thought of passing my iPod Nano 7g through USB/IP to my Proxmox Windows iTunes VM, but I never had the urge to do it. Although it'd probably work and would be great in combinaton with Wireguard on vacation, I did not want to setup a "risky" driver / kernel module on my main proxmox server :-) USB passthrough always was enough.
It may not be well known that VMWare Fusion supports this.
I run Windows on a Mac Mini functioning as an ESXi server.
From my Macbook Pro, I can connect to it with Fusion Pro and attach USB devices to the Windows VM. I use this to program ham radios and troubleshoot my vehicle with Toyota Techstream + USB OBD2 adapter.
Depends. There are still many enthusiasts (even new ports to random chipsets), but there is also a bit of a schism between the 9front folk and… let’s say our current timeline. The good news is that there are interesting things going on, fortunately none of which related to current tech trends.
I'd like to get a VDI infrastructure setup for me and my partner -- something that enables both of us to run our computers with a single big machine, and not have cables running everywhere through the house, while being able to sit wherever we want and use our infra from any given place.
At the moment, I've brainstormed:
- A main server that runs some type 1 hypervisor (Xen or Proxmox, will need to see which is more adequate)
- Light "client" devices (laptop, for example), that may either be connected in a wired manner to the server (e.g. separate desks), or remoting into it through Wireguard. Each desk will feature a KVM-style setup with a docking station that offers screens, keyboard, and a range of USB ports.
- Individual VMs for running our respective OSes to our preference, some flavor of linux distro. Inputs from the client device (e.g. USB, Keyboard, Screen) should be forwarded / matched to the VM.
- A windows VM for gaming, running two sessions for each of us: GPU passthrough is a must. I would like to make use of Looking Glass somehow, if possible either through the Linux VM on the same server, or on the client machine. The latter would probably be better for performance, I suppose, given you don't have to forward input devices twice... but I'm also worried about whether the buffer-copy mechanisms from Looking Glass would work with such a setup.
So far, I'm looking into Moonlight/Sunshine as a general desktop redirection setup: my hope is that I can pass something close to direct framebuffers on an ethernet connection while at home, and switch to compression while I'm away, hoping to achieve as little latency as possible in all cases (so giving absolute priority on the host to the streaming process, if possible, kind of like an RT system). One notable thing is that Sunshine by itself doesn't support generic USB redirection. Has anyone tried using usbredir for this purpose?
In general, it's hard to find relevant information for this kind of home hypervisor setup with a focus on gaming/latency and general transparency all around... would appreciate tips if anyone's attempted something similar before. Thanks!
I think just that it's plugged in at the SPICE level. So I guess you could redirect a USB device into a guest that isn't running Linux and can't run usb/ip? But also, this is how usb redirection works with virt-viewer/virt-manager, I'm fairly sure.
This would have been great for me to have around 25 years ago, when I wanted to mount a USB web cam in my bedroom window on the second floor and connect it to a computer in my basement. I was a dumb middle school kid and just spliced the usb wires onto Ethernet cable ends, and plugged them into the existing Ethernet run. That’s when I learned about maximum USB lengths the hard way, by frying some perfectly good hardware.
I would not expect this hack to fry hardware - at worst, voltage drop, interference, signal distortion, and impedance mismatch will simply cause the device to not work. But I've successfully run USB 2.0 over 30ft cables despite it being illegal per spec, so your idea wasn't radically wrongheaded. "Fried" is an extreme result - are you sure you didn't just connect V+ and V- backwards or something?
Yeah, probably just jerry-rigged an extension and plugged V+ into a data line or something like that. Properly wired, it just wouldn't detect the device.
I used this the other day with some of my proxmox VMs and it worked amazingly well. Pretty nice to be able to pass my usb via spice instead if needing to plug it into the server.
Funny how yesterday I was using Winding Sandbox to test a software and wanted to connect an iPhone to it, problem was that there’s not interface like a fully fledged VM and had to use VMware instead, maybe this will do the trick?
What’s input latency and throughput on this like? Would it support near native keyboard / mouse, webcam or display output? What about mass storage devices?
