Hi Pete,

when using ub with your patch i get a lot further:
the device is detected and uba+uba1 entries appear.
I can mount the device correctly.
Copying the files down and comparing them with the originals gives correct 
results.

but:
when i delete the files which are on the stick and do an umount/mount cycle, 
the files are there again. 
Copying files to the stick gives wrong results too.
Once the created file vanished after the remount,
and once it was there with a different name/size/date and garbage as content.

I didnt try ub without your patch (CONFIG_BLK_DEV_UB was disabled in my kernel 
configuration). Shall I try this too?

greetings
Martin
