Despite everyone saying "NT 4 doesn't support USB, Microsoft Tech Net and others point you to http://www.ionetworks.com . Their edgeport drivers for NT4 enable your USB chipset in NT. The problem becomes getting drivers for NT. Since everyone has the attitude that NT doesn't support USB, none seem to exist. In my case, I need a driver for my USB to SCSI adapter that hooks to my 2.2 GB ORB drive put out by Castlewood Inc. Works beautifully in win2k without any additional drivers, but I need some for NT4. I've called the manufacturers of the USB stack, the adapter, and the drive maker, no response from any of them. grrr....why make usb support if no one will use it?
