One of my offending devices is a idVendor=13b1, idProduct=0041 from Linksys so probably clearly not Lenovo, was just plugged into a Lenovo hub. The other one is a idVendor=17ef, idProduct=7214 so actually a Lenovo travel hub. And probably rightfully getting a pass-thru ... if we want to keep that feature in the kernel and not push it out to udev (for all vendors) Anyhow, it seems like the revert is coming. And i will disable that feature in the BIOS to be sure. But i will be happy to test further patches. regards, Henning > Aaron > > > Regards > > Oliver > >
