Although you will usually want to look up the raw PCI/USB IDs rather than rely on the strings provided by your operating system.
Note that this only works if your system actually can find the PCI/USB IDs for your hardware in its database (adding entries to the list is easier than actually writing drivers for devices, so the probability of this working is relatively high but not 100%). If your hardware is completely unrecognized though, this won't work.
Of course, this may not tell you the exact chipset -- usually, for that, you'll have to look at the chip itself and read the markings off of it. You probably don't want to pull your laptop apart to find that out, but if it's a popular laptop, you can often find out what other people have found inside by looking on sites like iFixit.
