302 Help! PB302 doesn't mount over USB

[fragile]

Folks,

I got this device just about 3 months back. Late December. When I plug it to USB, I'd see it show up as two drives in my computer: One for the miniSD and the other PB302s own internal drive (which hosts its root directory, the one with /system etc..). Over the course of 3 months I've transferred a few books and installed a couple of apps.

All of sudden since yesterday, when I plug it in USB, PB302's internal disk doesn't seem to be recognized by the computer. Only the miniSD shows up.
I'm pretty sure its not a USB issue since the miniSD shows up. The device as well shows the sync icon once connected over USB.

The internal drive however seems to be accessible to the 302 itself. IOW, I'm still able to read the books in the 302 that were on that drive. Through poterm I got the output of the dmesg in the PB302:

Has anyone faced this problem before? Can anything be done about it.
Any information that you can shed will be very useful to me.

Thanks!
