Calibre unable to read from prs500

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.

Code:
Job: Get list of books on device
**Error**: Could not read 4096 bytes on the bulk bus. Error code: -116
**Traceback**:
Traceback (most recent call last):
  File "calibre\gui2\device.pyo", line 20, in run
  File "calibre\gui2\device.pyo", line 123, in _books
  File "calibre\devices\prs500\driver.pyo", line 159, in run_session
  File "calibre\devices\prs500\driver.pyo", line 800, in books
  File "calibre\devices\prs500\driver.pyo", line 159, in run_session
  File "calibre\devices\prs500\driver.pyo", line 480, in get_file
  File "calibre\devices\prs500\driver.pyo", line 397, in _bulk_read
  File "calibre\devices\prs500\driver.pyo", line 384, in bulk_read_packet
  File "calibre\devices\libusb.pyo", line 251, in bulk_read
Error: Could not read 4096 bytes on the bulk bus. Error code: -116
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.

try a rebooting your reader and changing the USB port you use on your computer. That error indicates problems in the USB communication with the device

I am also having trouble connecting to my prs500 from Calibre. I was using the Sony Connect software, that (still) works but Calibre does not see the device. I cannot see it through Windows Explorer either.

I ran prs500 info and got the following error

Traceback (most recent call last):
File "main.py", line 337, in <module>
File "main.py", line 208, in main
File "calibre\devices\prs500\driver.pyo", line 193, in __init__
File "calibre\devices\libusb.pyo", line 344, in get_device_by_id
File "calibre\devices\libusb.pyo", line 328, in busses
calibre.devices.libusb.Error: Could not find libusb.

Thanks in advance.

Does that mean I just have to uninstall CONNECT from my PC or I have to do something more? I plan to use Calibre because the interface is so much better than CONNECT (which I dislike!!)

I couldn't find the calibre driver on my system so I uninstalled just the one. Then rebooted. For some reason the calibre driver still wouldn't install. Plugged the device back in and inevitably the CONNECT driver auto-installed.

I then performed a manual driver update, browsed to the location of the calibre driver, ignored the unsigned driver warning and rebooted again. Now I can see the device in calibre...no more tearing my hair out with CONNECT

for a great application!!
