Something like : $dev: Successful last sector success at xxxx, device xxxx $dev: Your device may need an an unusual_devs entry , please contact <some mailing list> ( Also why don't you guys introduce some CONFIG_KERNELOOPS_ORG_REALLY_SPAM_ME and let the user or distros which are using kerneloops.org to decide whatever to enable or disable these warnings ? ) However while trying to add an unusual_devs entry for my device I got the following error message when running lsusb -v -d the_device : ... can't get device qualifier: Connection timed out can't get debug descriptor: Connection timed out cannot read device status, Connection timed out (110) ...

This is probably some different bug / feature ? :) Since I get now a bit confused about all this warnings , it is OK to add any entry for that device or it is broken ?
