Ok, thanks.

Interesting - those interrupts are through the GPMC bus? I assume then
the kernel module collects the interrupts, and passes the data to
userland (i.e. UHD).

One more question - about cabling this time. Does the UE100-KIT come
with any adapters to assist with plugging my standard sized USB
devices (keyboard/mouse, flash drive, etc.) into the various USB ports
on the front panel? If not, can you describe which port is which type
- the serial console port looks like a mini-B, and the USB OTG and
Host ports look like they might be micro-B's, but I'm not familiar
enough with the mini/micro USB ports to tell just from the picture on
your data sheet.
 Thanks again,

Doug Geiger
