I've had this problem since 4.127 and updating doesn't seemed to make a difference. When I connect my prs500, it detects that my reader is connected but I can't view any books from the device or memory stick through Calibre.

I keep getting this error.

Job: Get list of books on device
**Error**: Could not read 4096 bytes on the bulk bus. Error code: -116
**Traceback**:

Also, when I try to send files to the reader, it will give me an error saying unable to send. But when I checked my reader, it is there. Only the books in a collection will be separated.
