Public bug reported:
After upgrading to Ubuntu 26.04, my Mousetrapper Advance 2.0 (USB ID
0d24:000b) no longer works in GNOME (Wayland). It worked before the
upgrade.
The device's USB serial number contains a control character (0x14). From
dmesg:
usb 1-6.4.2.3: SerialNumber: 7W5715\x14
The kernel enumerates the device fine and evtest shows events on the mouse
event node. "sudo libinput debug-events" also shows POINTER_MOTION. However,
the cursor does not move.
With udev debug logging enabled, every plug-in produces a batch of:
systemd-udevd: sd-device-monitor(manager): Failed to create device
from received message: Invalid argument
"udevadm test" on the parent input device shows:
input57: sd-device: Failed to handle uevent entry 'UNIQ="7W5715
"', ignoring: Invalid argument
0003:0D24:000B.0016: sd-device: Failed to handle uevent entry 'HID_UNIQ=7W5715
', ignoring: Invalid argument
As a result, the device's inputN nodes are never processed: they get no
"seat" tag and do not appear in "loginctl seat-status seat0", so logind does
not hand the device to the compositor. Re-triggering with "udevadm trigger"
does not help, since the re-sent uevent is dropped the same way.
Expected: udev should tolerate (or sanitize) a malformed UNIQ/HID_UNIQ value
instead of dropping the whole uevent, as earlier releases did.
Other devices on the same dock (Logitech wireless mouse/keyboard) work
fine.
