I am unfortunately still seeing the suspend/resume issue which I linked in the inital report: The drive works if it is attached while the system is running. It is not accessible anymore after a syspend/resume cycle that lasts a bit. (A few minutes seem to be sufficient.) I do not know any good kernel version for this problem. Plugging the device in while the system is suspended does not work reliably too, yielding a similar error, just with a few more retries: Suspend/Resume: usb 4-2: USB disconnect, device number 9 usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 10, error -71 Plugged before resume: usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 12, error -71 usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 14, error -71 usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 16, error -71 usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 18, error -71 usb 4-2: Device not responding to set address. usb 4-2: Device not responding to set address. usb 4-2: device not accepting address 20, error -71 A usbmon log is attached for the Suspend/Resume case running 3.11-rc3 + the patch you pointed me at.
