The USB port on my e4200 has stopped working completely after I tried to use an external hard drive. Now, whenever I enable USB in the services tab , the router will brick when reboting, and will need a 30/30/30 reset to work again. Using a serial adapter, immediatly after USB is enabled I get the output below (there is nothing pugged in the USB by the way):

Code:

The current build on the router is 24461 mega, but I have tested others with the same result.
I know the risks, but can the OC protection be disabled somehow though software or hardware?
