wrt-54gs v1 (wrt-54g v2) usb mod memo:
-usb pinout: rh19 usb1_dp, rh20 usb1_dn, rh21 usb2_dp, rh22 usb2_dn
(These four "rh" resistors are connected from ground to usb signal lines)
-according to the usb 1.1 specification 15k ohm should be placed between signal lines and ground.
so the orignal "472" resistors( all four of them) should be replaced with 15k ohm resistors.
-ESD protection diode and 22 ohm series resistors should be used(they are optional, but i have used them anyway)
-wrt54gs v1 (wrt54g v2) supports 5v power, I used a high quality 5v 2a one.
so happy right now
