to use the internal usb-ports on cf-29

today i checked the pins on cn18, cn49 and cn52.
i found on this connectors 3 usb-ports.
on cn52 is the on/off-switch for usb on pin 3.
i can control it with the wireless-switch-utility which comes original from panasonic.
if its on there is 3,2V and off 0V.
i used it with a complementary-darlington-circuit to switch on/off the usb-power on the port. the transistors are uncritical but must be minimum current 1A-type.


E ______ +5V (Pin4,5 cn52)

it wrapped the spaces...:-(
tomorrow i will draw it....
good night


so folks here is first an image of an darlington circuit:

i used picture 3.3:
Point B is connected to Pin3 on cf52 trough an resistor with 4.7k, point C is going to the pins 4 and 5 on cf52 an finaly point E is the output to the positive Power from the usb-device.

to connect a cable to the hirose connectors i used an defective tft-display. on the panel are flat stripes with many cables inside. the distance is the same like hirose used. i cuted from the stripe all unused off, so i have an good 12pin cable for cn52 or even an 40pin cable for cn18 and cn49 with soldering points on one side and a blank side for the connector on the board.
soldering should be done with lower temperature and fast. if all cables are soldere,d u can use hot glue from the pistol to fix it mechanical.
