CHIRP

I recently received both a QYT7900D and a Radioddity QB25 as gifts and tried to program them using CHIRP. As with other users on the forum, at first the only thing that came up were the Bluetooth ports, but after following the directions on the website, I got the Prolific chip to show up in a third USB port. The problem now is that importing or uploading to the radio yields the same message that the radio will not enter clone mode. The cable does not have a name on it, so I don't know if it's a genuine or fake. However, it came with one of the radios, but I don't remember which one. CHIRP works perfectly with the Baofeng BF-F8HP HT that I was given. Start with a different new cable?
