Mass storage driver stopped working

[dimag0g]

Dear all,

I have a problem: my Pandora doesn't work as USB mass storage anymore. Whenever I choose an SD card to share and connect Pandora as a slave, nothing happens on either end.

Here's my lsmod output before I share:

This is happening to me a second time and I know a reflash will help, but it's not really an option to reflash every month, so I need to find the root cause.

Any ideas on what I should check?

Are usb-net + scp an option ?

Are usb-net + scp an option ?

I doubt many printers are able to print from (or scan to) an scp storage, so not really.

EDIT: by the way, nothing seems to happen when I connect my pandora to a PC with g_cdc module loaded either.

For future reference, the issue was fixed by resetting the contents of /lib/modules directory to its initial state.

Case closed.
