i found the solution .
the board had some missing component
usb port micro is solder.
r55 and r 56 are shorted (near usb micro)
r17 560ohm (betwenn ethernet and normal usb port)
zener 4.7v (option).(it is subtitue of TPD2EUSB30DRTR ). if u want to solder it.
connet zener anode to ground.
cathode must be connect to r17 (pin of r17 with is not conneted to usb 5v)
after that driver will be automatically detected . it will take time.
use remotedestop v2 from toradex
now this are working fine.
