Hi,

Sorry for the delay.  I was away from the device.

Okay, I had to manually unbind usb_storage from the device first (using
instructions at http://lwn.net/Articles/143397/).  Unloading usb_storage after
switching modes does seem to fix the problem.

A kernel upgrade is not an option for me right now, so I'll need to apply this
work-around.  Does the usb_storage module actually need to be unloaded, or is
unbinding sufficient?

Can a general fix for this be implemented in the kernel itself?  If so, I'm
happy to help out by testing.

Thanks for your help, Oliver.
