My Kindle 3g (special offer) always enters into the USB LOADER MODE every time after released from the holding of reset button for longer than 15s. Using 'lsusb' command, I found the connection periodically lost after 90s and then reconnect after 3s. Is this normal?
Maybe it's the reason why LED light went out after hours of connected to charger or PC.
info=`lsusb | grep -i free`
if [ $? -eq 0 ];then
