Thanks for confirming that!

On the other hand, patch seems to be good, even for upstream.
From the merge request comment:

"""
ACTUALLY, it made little difference because the new rules:

Oct 04 09:34:46 macbook systemd-udevd[30592]: Process '/usr/bin/sg_inq --export --inhex=/sys/class/scsi_device/2:0:0:0/device/vpd_pg80 --raw' failed with exit code 15.

Still don't consider USB bus exception. The rule you mentioned checks for anything (else) then /dev/sd* or /dev/sr* which is not the case for pendrives, for example. Thus, the need for me to have added:

DEVPATH=="*usb*", GOTO="sg3_utils_id_end"

because:

E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb1

it the only attribute I could differentiate USB from SCSI BEFORE the actual VPD reading.

I'll suggest my change to upstream now, possibly mentioning a Forwarded item in the patches.
