Hi, (much better, thanks a lot.

Yeah, could you do a little favor ? run the commands below and the dmesg output after you see the failure: (cable disconnected) # dmesg -c # echo 5 > /sys/modules/musb_hdrc/parameters/debug (connect cable, cause the failure) # dmesg >> dmesg.txt reply this mail with the dmesg.txt attached :-) If you're using e.g. minicom, you can save the output of the serial terminal, that'll do as well. -- balbi -- 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
