BB rev A6 problem with Windows 7 x64


I have a home PC with Windows 8 (x64), and an office notebook with Windows 7 (x64). BB is easily accessible via Windows 8 (COM port is visible, and BB drive is showing when it has to). So BB is working!

The problem is in Windows 7 (odd, huh?!) because Device Manager says “Unknown device”. FTDI driver and 64bit driver for BeagleBone are installed.

Even if I manually select driver for this “Unknown device” and get a COM port, I still cannot connect to it.

I’m using Win 7 in english.

Do you have any idea, guys ?
