Tashkinov (aros@xxxxxxx) --- (In reply to Alan Stern from comment #1) > These messages indicate that the device's firmware doesn't conform to the > USB specification.

Since these messages can be seen at: dmesg -t --level=alert,crit,err,emerg,warn is is it possible to decrease their level to e.g. notice or info? I've google for it and there are literally hundreds of affected systems. I don't think it's worth alerting the use to something they are unable to fix or get fixed. -- You may reply to this email to add a comment.
