Stupid me. I didn't know until then that there is so much documentation
already included with the kernel sources...

Well, I hope I did this right.

This is the patch:

I hope there is no problem with the line wrapping and I did this
right... first timer :-/

The patch applies to version 2.6.4 from www.kernel.org. It also works
with Con Kolivas' sources version 2.6.4. I guess if all the symbols that
are being used in the unit entry haven't disappeared from later kernel
versions then it can be applied to later (or earlier) versions as well.

The device I'm using wouldn't work without this modification. It didn't
show up in /dev but I could read the Vendor ID in "usbview" and this led
me to a very old entry in Red Hat bugzilla:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=80328

Seeing that there already was an entry in
drivers/usb/storage/unusual_devs.h for EagleTec I only changed the bit
for the firmware version and it seems to work just fine.

Testing: I have successfully mounted a fat32 drive and read, deleted and
written (modified) files after applying my changes to the kernel.

Since this device seems to be very popular in Germany due a recent
catalogue offer from www.pearl.de for less than 10€ I guess a great deal
of users would benefit from the addition. The "Pocket Boy" I own is a
USB 1.1 device. There is a similar device from the same vendor with USB
2.0 that is also called "Pocket Boy". I don't have one though so I don't
know what kind of chipset it is depending on.

I hope this information is conforming to submitting standards. Please
feel free to correct me on any mistakes I made.

regards,
Tobias Weisserth
