What was a 60 mhz Pentium system doing with a USB port? It certainly didn't come with one, as by the time USB was released in mid 1996 the FDIV pentiums had been recalled for a year and a half (December 1994). USB support on Windows didn't really get acceptable until windows 98 and even then it wasn't good, so I'm not surprised the USB Ethernet device didn't work out.
I could be wrong considering it was over 2 decades ago and I never verified the floating point bug. There were no expansion ports on the computer and so I was using one of the built-in USB ports as that was the only expansion possible. This seems like the motherboard it would have used https://pb.retropc.se/770.html
But yeah windows 95 did have very limited USB support based upon the 2nd service pack if I remember correctly but it did not really work very well.
Yeah, USB + Ethernet [+ Firewire] all-in-one cards used to be reasonably common, because many motherboards in the PII-PIII time didn't have USB or only had two USB ports, and a lot also did not have an on-board Ethernet port.
