Nook no longer connecting to Calibre

[amber_missy]

Hi all

I'm in the UK and use a Nook Simple Touch.

I'm using Calibre for e-book management, and everything was great until recently, when my nook started to fail to connect to my laptop / Calibre properly.

I keep getting an error.
"calibre, version 8.16.1
ERROR: Error: Error communicating with device

The above exception was the direct cause of the following exception:

I have tried resetting the nook, tried different USB data cables, and I am still getting the error.

I have backed everything from my nook microUSB onto my hard-drive, but would rather just get it working, rather than have to start again with a different e-book reader.

Any suggestions?
Thanks in advance
