Just wanted to update what i got so far.
First guess due to the constant restarts was that the B190 needs more power over the USB than my PC gives. But even with active hub it doesn't work.

I opened up the router and started probing some testpoints. I still can't post images (10 posts limit), but it seems i found an active UART, will try to connect it with my pi today. I also eventually found JTAG, but i still have no idea what the micro-usb is doing.

When i power the device with socket-outlet, the micro-Usb starts transmitting on two pins (same signal) and ground is connected. No Vdd.

I also found an unpopulated interface, looks like another micro-Usb (sorry, no image possible).

Will report further when i find more.
