BB USB Port Schematic 8100 - GSM-Forum

Orange_Dominica · 07-02-2009, 15:32

Hi...

This may be of help to someone repairing the USB port...when the connection pads on the PCB are MISSING

I only managed to locate the connection points for D+ and D-

Need some more work to find the USB V+ connection and the USB ID connection

Note... you can remove this chip shown on the pic and solder your connections to its output pads.

Im almost certain that this chip is an ESD filter which is in series with the USB Port.

There are no skems for BB !....so if anyone can please add on to this thread to locate the USB V+ and USB ID connection

According to the diagram..it looks like BB dosent make use of pin 4 USB ID.
In that case.. just by applying voltage and GND, the BB should go into the charge mode

Excellent work MR. SDTV !
Your time and knowledge is honored
