X310 w/ Twin RX unable to use both channels

[alphafox02]

Looking over the tickets it seems there's already a desire for dual channel usage with various USRP devices.

With the X310 and one Twin RX card installed, I've yet to see any way to open and use both channels at a time outside of using GNU Radio with a UHD Source block and two channels configured. In this case, the channels are not combined of course, but instead I can open and view 80Mhz wide bandwidth on each channel and within different parts of the spectrum.

I figured if there's some way, say via soapyuhd/soapyremote to open both channels at one time upon first use of the device, maybe somehow applications which use soapy could then be opened twice and allow accessing each stream separately.

I've not yet tried the fix for the rate test described here, #46, but would this be a step in the right direction for soapy to use multiple channels at a time with UHD?
