I assume that another device is related to this usb path and overrides
this. Maybe /sys/bus/usb/devices/2-2/usb_device/usbdev2.2/? Here I get:

This program is for debugging only, it does not run any program,
specified by a RUN key. It may show incorrect results, because
some values may be different, or not available at a simulation run.
Which indeed would change the group of the device back to 0, and which
correlates with the udev log I provided earlier.
What is the relation
between /sys/bus/usb/devices/2-2/usb_device/usbdev2.2/
and /sys/bus/usb/devices/2-2?
Thanks,
Joachim
