Hi Phil,

Yes. The traditional Baofeng labeled programming cable has a
counterfeit Prolific PL2303 USB-to-TTL chip inside. More recently
Baofeng labeled programming cables have been shipping with the WCH
CH341 USB-to-TTL chip.

The shell of the USB end can usually be easily be removed allowing
access to the RXD, TXD and GND terminals of the USB-to-TTL module
inside.Visit this page and scroll down to "Cosmetic Retrofit".
