On my Galaxy Note II (android 4.1.1), any time I try to connect to something over USB, it doesn't seem to want to connect. Specifically:
-iSyncr gives me errors connecting; so does Android File Transfer
-DoubleTwist and EasyPhoneSync can't connect at all
-Odin gets stuck at "Making Connection" (or something, I can't remember the exact wording)
These problems occur whether I have USB debugging on or not, and still persist when I mess around with the MTP/PTP settings. Does anyone have any idea what might be wrong? iSyncr used to work fine, but the others have always been broken.
Note: this is on a mac, and Odin is run through a virtual machine
