Comment 4 for bug 400652

Ok, to repeat some information from the other bug:

With the patched kernel, both storage devices report a size which is reduced by one (to an even number). While this looks ok so far, only one of them works as expected. The other still fails with the "no sense" problem.

I started a debug howto at https://wiki.ubuntu.com/KernelTeam/Debugging/USB (if you find mistakes, please let me know) which should help to gather more data.

Could you provide the output of /proc/bus/usb/devices and (if you use the same port it should be bus 4) the trace of the usb bus as described there (from inserting the phone to after removing it)? Thanks.
