Package: udev
Version: 175-7
Severity: normal
Dear Maintainer,
The 60-persistent-input.rules rules create identical by-id symlinks for two
separate event devices, rendering the first unaccesible by-id. The "winning"
symlink seems to be random, with a strong preference for event11 (which is
not hte most usefull interface)
The /dev/input/by-id/usb-Microsoft_Microsoft®_2.4GHz_Transceiver_v7.0-event-kbd
is created for both /dev/input/event2 and /dev/input/event11.
Below is the output from udevadm info --query=all for all devices created
when plugging in the hardware. Note the duplicated entry:
