Randy,

A similar situation also exists with cable using FTDI USB-to-serial chips.
This is another case of a cable manufacturer using a clone (counterfeit)
chip instead of a genuine FTDI chip, and FTDI drivers for several years
have not worked with the clone chips.  I don't know if an older FTDI driver
can be found that will use the clone chip, but other Chirp users may be
able to guide you.  As soon as I receive a new cable I check it to be sure
it used a genuine FTDI chip.  If it's a clone chip, I return the cable to
the vendor.
