Or just "it works > most of the time"? Sorry, I should've clarified that. "Used to work" is supposed to say "the device used the generic cdc_ether driver", as in [ +0.000004] usb 4-1.1: Product: Lenovo Powered Hub [ +0.000003] usb 4-1.1: Manufacturer: Lenovo [ +0.000002] usb 4-1.1: SerialNumber: xxxxxxxxx [ +0.024803] cdc_ether 4-1.1:2.0 eth0: register 'cdc_ether' at usb-0000:2f:00.0-1.1, CDC Ethernet Device, xx:xx:xx:xx:xx:xx I guess it did technically work correctly, except for the reported issue when the host system suspends, which is fixed by using the dedicated Realtek driver. As far as I know this hasn't been fixed before, so it's not a regression. Should I update the commit message accordingly? Thanks! Leon
