Ethernet-over-USB problems under 4.1.10-ti-r21

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:

owlstone@BBBKME9205EB:~$ ifconfig 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:
https://github.com/beagleboard/linux/issues/48

fix:
https://github.com/RobertCNelson/ti-linux-kernel-dev/commit/1d9085bfb11e9e35ab0f4262799c8c801219a84f

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

What rootfs did you use? (name and date)

No clue…
this is the output of some fsroot related command I found browsing:

So you didn't download it from somewhere? it was just given to you?

cat /etc/dogtag

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:
owlstone@BBBKME9205EB:~$ cat /etc/dogtag
