It's hard to say, but this sounds like a power issue to me. The
UM720S consumes more than the 500mA of power given by the USB
specification. That works with most PCs, but perhaps not with the
SheevaPlug (especially for the current rush at power on).
Have you tried connecting the Mimo monitor through an AC powered external hub?
