Every 2-3 weeks, the internal USB adapter fails. I can fix it by just 
moving it to the other USB port. In another 2-3 weeks, it will fail 
again, and I move it back to the original USB port, and so on.

No problems with the external RJ45 interface.

The logs aren't very helpful:

This looks like a USB problem. Is there a way to get usb (or 
NetworkManager) to reinitialize the driver when this happens?

I would ask these people for advice, therefore.
