The GPIOs generate interrupts.  The GPMC is for data transfer.  In any 
case, our kernel driver handles all of it for you, and you just need to 
use the UHD just like on any other USRP.

The serial console uses a standard mini-B which is very common.  Micro 
connectors are different.

The OTG and host ports use mini-AB connectors.  The host needs to have a 
miniA cable and the OTG port uses either miniA or miniB.

We are including a mini-A to female A adapter with the purchase so you 
can use your standard cables as included with hubs or mice, etc. or as 
built into your flash drives.
