Hello everyone,
This is the first patch I ever try to submit, so please forgive me if I'm
doing something terribly wrong. :-) Anyway, I have a 128 MB USB Memory Key
by IBM, and without my patch it doesn't work at all. It was telling about
"usb_control/bulk_msg: timeout" all the time.
Then I did find out the other IBM USB Memory Key patch already submitted
to some 2.4.21-pre kernel and just changed the idProduct to match with the
one I have. Voila!, the memory stick started to work.
Here's the patch against kernel 2.4.21-pre4:
