I'm getting these urb aborted messages. [125054.082248] peak_usb 3-2.4.4:1.0 can0: Rx urb aborted (-71) [125077.886850] peak_usb 3-2.4.4:1.0 can0: Rx urb aborted (-32) Is there anything that can be done about this? This is very frustrating because it makes the USB adapter very difficult to use as a reliable partner of an embedded CAN device. I'm using Ubuntu with 5.4.0-107-generic. Any help would be appreciated. -Paul
