I recently bought an RSPdx and tried connecting it to my Asus ZenFone 5Q with a USB OTG jumper and USB cable. I ran SDR Touch and tried to pull in signals from the RSPdx, but all I ended up with instead was an error message: “No compatible devices found (make sure your USB device is connected, properly powered and your phone/tablet supports USB host mode)”. All of my attempts to enable USB host mode on my phone have failed. Am I missing something? Can anybody offer me some clues?
Not sure if it’ll work but another forum recommends you use a 5v dc powered USB hub “1) You MUST provide a D.C. supply to the RSP: To do this you use an external USB hub complete with its own 5 V supply.”
