You might try running your USRP and HackRF on separate USB controllers.  Different ports on the same controller, *might* be leading to conflicts in packet scheduling at a fairly-low layer in the stack.  I think HackRF uses libusb, just like USRPs, so they are subject to the same constraints in underlying USB drivers.

Has anyone used a USRP and Osmosdr source together on the same graph? I am trying. To run a HackRF and an Ettus b200 together and I am getting a lot of 'D's. I have tried putting both at a low sampling rate but it doesn't seem to change things. I am running it on an i7 so there should be enough CPU. Could it be a USB issue? Could the drivers be interfering?
