OK, I recompiled the kernel to include only USB
support, making usbserial and whiteheat loadable as
modules (with verbose debugging defined).
I am loading them using "insmod usbserial debug=1" and
"insmod whiteheat debug=1" as you suggested. The log
file looks as it did before (White Heat converter now
attached to ttyUSB0 ...).
When I issue a cat "hi" > /dev/ttyUSB0, I get the same
error message as before "cannot create /dev/ttyUSB0:
Connection timed out". There are no additional
messages written to the kernel log when I issue this
command.
Interestingly, if I do a "mknod ttyUSB93 c 189 0"
where 189 is some bogus driver number, I get "cannot
create /dev/ttyUSB93: error 19" and the kernel log
shows "modprobe: Can't locate module car-major-189"
which implies that linux is making the association
between ttyUSB0, driver 188, and usbserial.
thoughts?
Thanks!

just fine.
Load the usbserial and whiteheat drivers with
"debug=1":
insmod usbserial debug=1
insmod whiteheat debug=1
and take a look at the kernel debug log when you try
to access the port:
cat "hi" > /dev/ttyUSB0
Let us know what it says.
thanks,
