I've updated the patches for 2.6.18 below based on the linux-omap tree
snapshot. This udpate fixes a nasty bug with host mode TX fifo flushing,
so now all the Linux testusb testcases run reliably.

I've still seen some failures writing large files to USB sticks, that
does not seem to happen with 2.6.21 from linux-omap tree though...

Regards,

Tony
