I have never tried transmitting i only use SDR#

But I do have a ASUS Z97 motherboard also and i have issues on receive with Cypress (Bizzarly works set on 40Msps but drops at lower rates))

I am ok using the Lib drivers so to be sounds like your hitting a cypress issue.

I'll spend some time looking into this to determine if the underlying issue is in our codebase or in the Cypress's driver. Unfortunately, if it's the latter, there's not much we can do other than run it up the flagpole to them.

In the meantime, it might be worth sticking with the libusb driver.

Best regards,

Hi Jon,

Thanks for your feedback. I really have no clue of what's the problem.
Let me know if you want me try something on my end, it's very quick to setup.
Also, I can recompile easily libbladerf under Windows now, if you want me to try a modification in a special branch.
