Re: [RE: [iPAQ] USB for SA11x0]

This works great. I got the usb client and host working. I used both a test8
kernel and test5 kernel on the host side to test it out. Seems to be quite
buggy. pings worked, sometimes. rlogin to the ipaq failed 2 of 3 times.
debugging errors were very verbose. I can forward on the errors to interested
parties. But definitely not ready for prime time. I would recommend that
charlie flynn take a look at it and compare it to what he's done/taken over to
see if there's overlap and how to proceed so as to not duplicate effort.
Great work brad parker and Nicolas! Almost there!

Try copying drivers/block/flash-mem.h from the handhelds.org tree over the
one in my patch.

Take a fresh 2.4.0-test9 tree and copy drivers/usb/usb-net-host.c from
the patched tree to the unpatched one. Next edit drivers/usb/Config.in
and drivers/usb/Makefile to add the single line dealing with
CONFIG_USB_NET_HOST to reflect the patched tree. Then you should be able
to build yourself a 2.4.0-test9 tree with usb-net-host module for your PC.
