Please try this experiment: Before plugging the card reader into the USB port: sudo modprobe usbmon sudo cat /sys/kernel/debug/usb/usbmon/1u >/tmp/usbmon.out Then insert the card into the reader and plug the reader in. Wait 2 minutes and then type ^C to kill the "cat" program. Post the contents of /tmp/usbmon.out so we can see what happened.
