Stanislaw and Helmut,In a bug report at https://bugzilla.suse.com/show_bug.cgi?id=1055826, the OP reports that his RT3572 fails to work after an upgrade from the openSUSE Tumbleweed kernel 4.12.7 to 4.12.8. I checked the kernel configuration and did not see any problems.
Are you aware of anyone reporting problems with rt2800usb in 4.12.8 kernels? Thanks, Larry
