            Bug ID: 212751
           Summary: acm_port_activate - usb_submit_urb(ctrl irq) failed
                    after kernel update
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.10.30
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: johann.wilhelm@wilhelm.consulting
        Regression: No

Something between 5.10.26 and 5.20.30 broke (at least) the USB CDC
implementation by ST Microsystems on their STM32 devices.

On opending of the device following error occurs:
[ 1333.790160] cdc_acm 1-10:1.0: acm_port_activate - usb_submit_urb(ctrl irq)
failed


5.10.26 works - 5.10.30 does not.

Tested on the 2 identical devices with 2 different firmware (read: different
firmware from 2 different developers) on different ports (USB3&USB2) with and
without hub.

Additionally, someone else reports similar problems here:
