Hi JVP, thanks for testing the Bret Johnson USB drivers :-)

If you run cwsdpmi like that, it will probably not
stay in RAM? Apps made with FreeBASIC will just load
cwsdpmi themselves while they are running and will
unload it afterwards :-). In short: Things should
work at least equally well without that line...

I assume the IRQ can also be set automatically?

Cute :-) Does it support more advanced PS/2 commands
as well, in other words, can things like third button
and wheel be enabled by the ctmouse usbmouse combo?

Great news :-) I remember running something with 1 msec
TSC based time measurements on a classic Athlon a few
years ago - there the BIOS USB driver did cause delays
big enough to make me switch to real PS/2 mice again.
