I am using USBizi100 pin IC for a custom board which i am trying to connect through USB. USB schematics is based on the reference schematics -FEZ Panda II.
When i try to connect to USB the poer led in my board glows which indicates that USB connection is established.But mfdeploy is not able to detect the device.

The voltage at the USB-CON pin is around 2.3V and i gueess because of that the PNP transistor is not turning ON.

Please note that the BL and Mode pin is unconnected .

May i know the default state of the USB -CON pin.

What is the exact function of this pin.

I sent you an email.
