One problem I've been having is that the rt73usb module seems to get in
a weird unusable state upon resume, but it's not mentioned in the stack
trace so not sure if it's related issue or not. That issue is that my
ralink usb wireless device is listed via 'lsusb', but shows up as
DISABLED in lshw. The only way to fix is to unplug/replug the device,
or remove and reinstall rt73usb via modprobe.
