I am loading drivers using just insmod. As you can imagine, it depends
of the order that I can load (for undefined symbols). If it is correctly
load, then insmod (I think) says "Load correctly" (aprox.)

i think that no DEBUG in this modules, but I will check

I am enabling DEBUG on host side, tomorrow morning I will check it with
device driver...

ok, i am preparing (I will finish later) Kernel 2.6.11 with Mike Lee
patch. With Mike Lee patch I think that I have to enable USB device
driver core and "Serial Port". When I will load USB device driver, using
lsusb in host I will be able to see PID and VID, correct?
(I think that yes, because Net2280 PCI Card is working in this way, but
I ask just in case. For example, lsusb is not showing any line for my
digital camera...)
(And I would like to work with 2.4.20 Freescale Kernel, I will do some
more tests too)
Thank you very much,
