Yes I did have the same problem in my home's router a while ago. I solved
this by changing the value in /sys/bus/usb/devices/3-2/bConfigurationValue
which was initially 0 to 1. the OP could possibly wrap this value nicely
in ifup so to speak.
$ echo -n 1 > /sys/bus/usb/devices/3-2/bConfigurationValue;
IMO this happens everytime theres a power shortage.
