I lost time on that, so it is recorded rather than left to be rediscovered. Both items are live on ratio and neither exists on velox. + +## Correction (winvm, 2026-08-08) + +The udev mechanism claim in section 2 above is wrong and stands corrected by +the sender: `TAG+="uaccess"` does apply to raw `SUBSYSTEM=="usb"` devices +(`70-uaccess.rules` tags them in several places). The real failure was rule +ordering — the ACL is applied by `73-seat-late.rules:16`, and a rule file +numbered `99-` adds the tag after that test has run. Every distro rule adding +the tag sorts at or below 70. + +The `GROUP="video", MODE="0660"` grant remains the verified working fix. +Untested hypothesis from the sender: a rule file numbered below 73 would +likely make uaccess work on its own (a tighter grant than the group). The +installer task ships the rule numbered below 73 with both mechanisms and +leaves the uaccess-alone test for when the camera is attached. |
