It contains fixes to USBD.SYS and more importantly the completely updated USBAUDIO package to support higher sample rates and bit resolutions.

Thank you Lars, I now have sound on several of my computers using a USB adapter.

One question, since you are the expert on USB drivers, is it possible to update the USBKBD.SYS to work with the extra keys on many new USB keyboards?  I have an old no name PS/2 that allows the use of those keys but non of the USB keyboards have any response (the keycodes don't appear in the programs I used to get them for the PS/2 keyboard.

Being called the "expert" is always a minefield  :)

Yes it would be possible for sure. Unfortunately, the HID spec (the specific spec for human input USB devices) is complex compared to the other specs and then I don't have the HW knowledge as to what special keys generate what scancodes. I would have to go through trial and error and I don't have the time for that.
There is some code and definitions currently commented out of USBKBD.SYS (don't know why. I did not touch that). Maybe it's worth putting that back in and giving it a try ...
