I can't see the BBB from my Win7-64 PC...
I connect PC to BBB USB cable and run BONE_D64 succesfully but BBB shows up in "Device Manager" window as"Other devices" with a question mark and a exclamation mark in a yellow triangle... see picture below.
Tried rebooting and power cycling with no effect.


Any known way to fix it?
Cheers

PS 
linux log when I try to force usb0:

Additionally there is not "gadget serial" driver so no serial over USB, either!

The USB client port on BB White was for me rock solid, always. Then I
got a BB Black. For a while the USB client port worked, but then it
stopped working, and I lost lots of time trying to get it work,
unsuccessfuly . Eventually I gave up on that port altogether. Instead
I use a FTDI cable connected to the debug port, an Ethernet cable, and
an external power supply.

There was an issue with 4.1.10-rt-r21, first fixed in 4.1.12-ti-r25:

bug report:


fix:

so either upgrade via apt-get to "linux-image-4.1.12-ti-r25" or the top of that branch: "linux-image-4.1.12-ti-r28"

I upgraded to "linux-image-4.1.12-ti-r28" and now Windows installs all drivers on BBB boot and I can see everything in the "Device Manager" window, but still I have neither serial-over-USB nor ethernet-overUSB connection to the BBB.

The "Network Connections" window shows the "Linux USB Ethernet/RNDIS Gadget" but it says "Network cable unplugged".
Terminal emulation on the Gadget Serial COM port just do not communicate.
Is there any investigation on the beaglebone side I can do?
Cheers

No clue...

I flashed 4.1.10-ti-r21 image from a link you pointed me to in an email from a different thread, to fix a USB problem.
Anyway:
