Solved Kindle SY69JL not detected by Calibre

[jungedame]

Hello, I recently installed Calibre wishing to transfer some books to my Kindle. The Kindle is detected on other PCs, so it's not a Kindle / cable issue. I followed the installation instructions, such as:

To talk to USB and MTP devices the user needs to be able to access the device node in /dev.

to be aware of USB devices attached to the machine, the user needs to be a member of the operator group: # pw groupmod operator -m yourusername

Then, add the following to /etc/devfs.rules, or create this file if it does not exist yet: [system=10]add path 'usb/*' mode 0660 group operator

To load these new rules, add the following to /etc/rc.conf: devfs_system_ruleset="system"

Then, restart devfs # service devfs restart

This is what libusb.get_devices() returns:

calibre-debug
Welcome to the interactive calibre shell!
Use exit to quit
>>> from calibre.constants import plugins
>>> libusb, err = plugins['libusb']
>>> libusb.get_devices()
[((0, 2, 32903, 2603, 16), {}), ((0, 3, 1266, 46507, 16), {'manufacturer': 'SunplusIT Inc', 'product': 'Integrated Camera'}), ((0, 4, 3034, 790, 516), {'manufacturer': 'Generic', 'product': 'USB3.0-CRW', 'serial': '20120501030900000'}), ((0, 5, 6473, 4, 784), {'product': 'Internal Storage'})]

libusb detects my webcam, but not my kindle.

This is whan camcontrol devlist returns

I mounted my Kindle using "mount -t msdosfs /dev/da1s1 /mnt"
It shows up in /mnt and I can access its contents.

However, my kindle doesn't show up when I open Calibre. I recently received this error in Calibre when trying to send books to the mounted folder.

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

Any help would be greatly appreciated, thank you.

Solved it by resetting the kindle to a blank slate - apparently that .driveinfo.calibre file wasn't allowing calibre to access the folder. Files transfer fine now when i select "Connect to folder" and link it to the point I mounted my Kindle at.
