Exclamation [Q] Internal USB gone wrong! Need Help!

I was attempting to solder in a usb flash drive onto the board for some extra internal storage, similar to what they are doing in this thread => http://forum.xda-developers.com/show....php?t=1866988



While soldering I accidently broke the piece circled in orange int he picture. I think it is a resistor? Can anyone confirm that and possible tell me how many ohms it is? The piece fell on the floor and is in my carpet somewhere. I would like to get a new piece to solder back in. Since the piece is missing my nexus 7 works fine except it can't go into OTG mode. If I connect a flash drive to the micro usb port with an OTG cable nothing happens and previously it would mount the USB with stickmount.

That is a resistor. When I get a chance I'll get the resistance for you, I'm in the process of moving my office in my house so I don't know exactly where my Multimeter is at the moment.

If I helped you on the forum please feel free to donate.

Still haven't heard anything. Can anyone check the resistance for me?

Have you had a look at Nexus 7 schematics?

Phones: Nokia 6230i -> Nokia N82 -> Sony Ericsson Satio -> Nokia N8 -> *soon* Nexus 4
Tablets: Advent Vega -> Nexus 7 QUAD ROM

I found this, http://forum.xda-developers.com/show...0#post31922480 , but it's way too complex for me. I have no idea how to find that one little resistor in the schematic.

My guess, please check the schematic on sheet 14 of 60 or page 14, look for r83. Value of R83 is 100k ohm.

please correct if I was wrong.

That definitely looks like a good guess. I might try that. Can anyone else confirm KVLV's guess?
