As soon as you plug your cable in the USB port of your PC it should find the drivers. Next look in your device manager for the com port that show the name Profilic in it. Also the com port must be below 10 CPS accept only com port from 1 to 9.
Next open your CPS look for the com port. Like the picture below. Then connect the cable to Radio and Power on you radio the normal way. Then you should be able to read
Another thing i dont see how you can program your radio in CPS if you have not read the radio.
You must read the radio. Save the original CodePlug then you program it from the codeplug you have read.
Let us know if you can read your radio.

Hi Allister, I'm having same issue with the Kydera that I just bought "new"? Long story. But it is not recognised by the computer.
I've seen this before in a Retavis ht and after digging around flung that the built in FTDI chip can be damaged by a lead with the chip in resulting in issue as we are experiencing here.
I hope you have a resolution to this problem and that you can share to avoid me arguing with the vendor of my radio.
Follow up on my issue. Fired up my old windows 8 laptop, downloaded RT73 cps from Retevis website plugged in Boafeng lead. Still no reading from radio. So installed old prolific driver. Still no reading from radio. Checked com port it was 38, moved to 2 and bingo! Read/write now work.
