E.g. pulling the USB under receive load brings this output: [ 1343.786427] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) [ 1343.786640] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) (..) another 344 of these URB aborted messages [ 1343.872620] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) [ 1343.872867] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) [ 1343.873124] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) [ 1343.873269] usb 2-1.4: USB disconnect, device number 6 [ 1343.873363] usb_8dev 2-1.4:1.0 can2: Rx URB aborted (-32) [ 1343.875259] usb_8dev 2-1.4:1.0 can2: device disconnected [ 1343.875366] usb_8dev 2-1.4:1.0 can2: sending command message failed [ 1343.875371] usb_8dev 2-1.4:1.0 can2: couldn't stop device Tomorrow i will do some more testing. The LED handling of the device is really fine: - interface down -> red - interface up -> green - interface error passive -> green blinking Regards, Oliver -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
