Hi thanks, I step through the code and found out that the
driver actually did not return from my startdevice
function. I also found out that my driver actually hangs
at a WRITE_PORT_USHORT statement and once that statement
is removed, startdevice function returns successfully.
Now I guess WRITE_PORT_USHORT hangs because my PCMCIA card
actually makes use of the WAIT signal in its I/O reads and
writes and I wonder if there is a way to specify in the
driver that I require the i/o to use WAIT signal. I can
do this easily in WinCE driver but not in Win2k driver.
Any idea?
