Some manufacturers have NT 4.0 drivers that are specifically written for their devices.
- Iomega's USB Zip and Jaz products do work on NT 4.0.
- PortGear's USB Ethernet also works on NT.
- Blue Systems make NT 4.0 drivers that work with some USB printers, Pocket PC USB cradles, USB keyboards and USB mice.
- HP PhotoSmart S20 USB film scanner works on NT too.
None of the USB webcams I have seen work on NT 4.0 though.
