What happens if the router is in a strange state and you just
disconnect and reconnect USB? Does this fix everything?

Assuming you can't power of the router and then you would disconnect
and reconnect the USB cable, could you after doing this power of the
router?

I wonder if the router and/or the PC's USB ports e.g. have energy
saving options.

"This setting takes effect when the router is running 
on battery power. When enabled, wireless network 
will be turned off when no wireless clients are 
connected to the router for more than the specified 
Maximum Idle Time. 
You can turn wireless back on by pressing the 
power button for 1 second.
Set the Maximum Idle Time for your wireless 
network before entering Power Save mode(if it is 
enabled). 
Determines the maximum number of wireless PCs, 
devices, and other clients that can connect to your 
wireless network." -

Is the above true for the USB network connection? Is getting power
from an USB port considered an external power supply or is it still
considered battery power?

Apart from the router's power saving options, are there any power
saving options for the PC's USB ports?
