When I try to use the api, the pogoplug running cgminer crashes.  I'm wondering if it has to do with running off a USB stick and cgminer using libusb.  I've been using since 3.8.  No console on pogoplug (without soldering a special USB cable - which I tried and failed).  cgminer does not run as root, so it really shouldn't be able to crash the system - unless it is one of those infinite thread/fork bugs.
