Conbee II not working / firmware not connected

I am having trouble with my Conbee II stick. It is not properly connecting to deconz / phoscon anymore. Logs can be found here: deconz debug log
Phoscon displays this:
I am running the stick on a Raspi 4B. I am using an extension cable (USB 2.0) plugged in a USB2.0 port. The stick is about 1m away from the Raspi and about 70cm from my router.
$ lsusb displays this: Bus 001 Device 014: ID 1cf1:0030 Dresden Elektronik ZigBee gateway [ConBee II]
$ ls -la /dev/serial/by-path/ displays this: platform-fd500000.pcie-pci-0000:01:00.0-usb-0:1.4:1.0 -> ../../ttyACM0
I tried doing an update but am not getting anywhere:

Any help is welcome! Thanks!

EDIT: I did not do any updates to the OS, didn’t add any devices, didn’t move the stick…it just stopped working :frowning:

Please check

Thanks, that was it!
