The kernel module is usb_storage (which has a bunch of other dependencies) - I just applied the latest updates to everything last night (there was a new kernel), and this morning plugged in my 8320 and it's charging fine and the SD card mounted (I wanted to get a pic off it). This is using the stock 'berry_charge' kernel module though, not any part of the Barry project.

Try stopping all Barry components from running, then plug in your BB and look at /var/log/messages - do you see a bunch of chatter about the SD/USB Mass Storage being found? Start with a basic "is it plugged in" test with nothing more than the stock kernel and go from there, worry about Barry later (just to take it one step at a time).
