cdc_acm 1-1:1.0: acm_port_activate - usb_submit_urb(ctrl irq) failed

I am trying to connect the arduino uno to the arduino Idle, but I've got troubles and I don't have any ideas how to fix it.

Thats the message from dmesg.

I had this as well, finally tracked it down to the kernel update from 5.4.0-73-generic to 5.4.0-74-generic on or around 10th June.

I used Grub to boot into 5.4.0-73 and all worked fine

This was on 20.04.2 LTS
