/dev/hdmi2usb/by-num/all 0 doesn't increment
I am assuming 3 devices should get all0, all1 and all2, but I don't see 1 or 2.
same with /dev/hdmi2usb/by-num/opsis
This might be due to #3

OpenOCD needs 666 permission to access device?
@mithro With current rules, OpenOCD is not able to access the device for programming. I needed to do this to make it work -> timvideos@806c2a0
Is it correct workaround? Or should I add device-specific match-filter there like this: ENV{ID_HDMI2USBDEV_BOARD}=="mimas_a7" ?
Atlys needs ttyVIZx
Atlys rules create links to ttyACM1, should be ttyVIZ0
