USB works in Win95 OSR2.5 and over There was no support at all when OSR 1 was out and there was a little support in OSR2.1 but had troubles, it used to cause locking up. I have a question I just installed PCI to USB Card into a Space shuttle Slot 1 motherboard runing celeron 300MHz running win98. Win98 detects it and installs the drivers. The mouse wont work, when you check systems settings/Device managers. It states that there is a data transfer error between the USB Root Hub, please check cabling and drivers and restart windows. In doing so it doesn't make a difference. Still comes up with this error. Any ideas whats going wrong here?? I have yet to try it on another PCI port.
