Having big problems with my 350. I plugged it into the computer tonight (it had 3 bars on the battery at the time) and up popped the message "USB device not recognized." Windows Explorer didn't show it as a pair of removable drives, and Calibre didn't find it. Unplugged it and it gave the "exceptional internal memory state formatting" message-- which gives no chance of canceling, there's only a "yes" button. I try rebooting the computer to see if it can recognize it (after it formatted itself), no luck. Did a soft reset, still the "not recognized" message. Did a hard reset, still "not recognized." When I plug it into the computer, the battery icon (on the reader) turns all black and a little arrow icon appears to the right of the battery icon in the bottom bar, and the red light is on at the top of the reader-- seems like it thinks it is connected to an external charger? I've never used an external charger before, but I've read that you can continue to use the reader while it is charging, and that would be an explanation for the little arrow by the battery.

Any ideas? Could there be a problem with the cable, or a physical problem in the reader? Since it formatted itself, I'm stuck with no books on the reader and no way to get them back on.
