I am going to assume that you do not have access to any of the Warp 4
post fp15 bug fixes. Open up DD02 (Device Drivers 2) fixpack
by unpacking the contents. There in you'll find the base USB device
drivers and keyboard and mouse drivers for USB. These were very buggy
and will not work on many systems. But they might work on yours. Add
this to your config.sys:
The first line is repeated as many times as you have USB controllers of
the USB 1.0 or 1.1 kind, usually one controller per two ports. Alas,
these USB controllers must be of the Intel UHCD kind, not the OHCD kind.
You must set BIOS to support legacy USB functions, in order for you to
continue to use the keyboard while booting (only apply if you are
intending to use a USB keyboard).
If your system uses OHCD controllers, then you can forget this. The
main board documentation will tell you which is used. Google on your
mainboard or vendor model if you don't have the documentation.
However, if you got the latest eCS, then it (all of USB drivers) should
already be installed on your system and you only have to remove the REM
from the lines in config.sys.
When the serial ports stops working, it is time to be ordering a new
main board, IMHO.
Thanks a Million!
