H3 and OTA dongle...which USB port?

will the dual ota dongle function with HWS or only H3?
It will function with any receiver (other than the ViP211z?) that uses a USB OTA dongle. The HWS and H3 are the only ones that currently let you use both OTA tuners, though. Hopper 1 and Wally still only use one of the two tuners in the dual OTA dongle.
