The first time I plugged in the PRS-700 on my 64-bit Vista machine, I got these USB Device Not Recognized balloons for the entire time it was charging. If I closed the balloon, a new one would pop up, until I've closed about 30 of them. I could read from the drives and use the Sony eBook Library software, everything worked fine.

Luckily it only occurs every couple seconds, but it piles up in the message queue so if you haven't clicked the balloon immediately, then it'll queue up a bunch of them and you have to close them all until finally it gives up and they stop.

May try plugging it directly into one of the main usb ports instead of through this USB hub I've been using.

Solution:

I decided to try plugging it into my machine directly, but figured I'd check the Sony Support site first and found this.

NOTE: The USB cable should be connected directly to the computer. Connecting the Reader using a USB hub or extension cable is not supported.

I would've tried this initially if it weren't such a pain to find a main usb port I could use, but in the end I opted to move one of my less used external drives to the hub (which is usb 2.0) and I don't get the errors anymore.
