Hello systemd devs and users,I need an advice regarding USB scanner which rule is not(?) processed at boot time. When I trigger it manually, the scanner device file gets proper permissions.
Here's the rule: cat /usr/lib/udev/rules.d/49-sane.rules |grep -A1 '1200 TA' # Mustek BearPaw 1200 CS | Mustek BearPaw 1200 TAATTRS{idVendor}=="055f", ATTRS{idProduct}=="021e", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes"
Here it is how it looks like directly after the boot: lsusb Bus 001 Device 003: ID 055f:021e Mustek Systems, Inc. BearPaw 1200 TA/CS getfacl /dev/bus/usb/001/003 # file: dev/bus/usb/001/007 # owner: root # group: scanner user::rw- group::rw- other::r-- And this is how it looks after triggering manually: udevadm trigger -c add /dev/bus/usb/001/003: getfacl /dev/bus/usb/001/003 # file: dev/bus/usb/001/007 # owner: root # group: scanner user::rw- user:mk:rw- <<<<<<<< NOW MY USER IS HERE group::rw- mask::rw- other::r--Of course this is the effect I expect to happen directly after boot. It changed most likely after I upgraded my PC hardware. I tried to downgrade systemd, kernel and sane without any positive effect. This was working for me this way for past 12 years ;)
I enabled udev debug level and browsed whole journalctl but haven't found there anything about my device (except the fact that it's detected by kernel):
journalctl -b |grep '021e'Oct 19 20:06:26 linux kernel: usb 1-6: New USB device found, idVendor=055f, idProduct=021e, bcdDevice= 1.00
I'm attaching the zipped log from systemd-udev.service. My hardware: Archlinux systemd: 246.6-1 linux: 5.8.14.arch1-1 sane: 1.0.31-1 libusb: 1.0.23-2 Motherboard: Gibabyte B550M AORUS PRO (rev. 1.0) Scanner: Mustek BearPaw 1200 TA CPU: AMD Ryzen 3 PRO 4350G with Radeon Graphics Many thanks for every tip I get to resolve this problem! -- Pozdrawiam / Greetings Marcin Kocur █
