Code:

cat /proc/devices |grep -i ttyUSB
188 ttyUSB

then I run
flasher-3.5 -c -S usb -h RX-44:0805 -F RX-44_DIABLO_5.2008.43-7_PR_COMBINED_MR0_ARM.bin -f -R

it stop at following place forever.

when use usb2serial wire connect to serial port on N810,
ie serial port on N810 end and usb port on PC end, what should be used for flasher-3.5 -S option, usb or ttyUSB or ttyUSB0 or /dev/ttyUSB0.

Anyone know this, please give some suggestion, thanks a lot for your help.
