[chirp_users] Baofeng UV-5R and settings/squelch_levels

You mention that you are using a cable with an FTDI chip and the Prolific driver.
It may be a driver mismatch. 

The FTDI chip requires the FTDI driver. The Prolific driver is for the Prolific chip only.

Could this be the issue?

Cannot get a driver to function on my w8.1 machine using

same cable (with FTDI chip), Win_Driver_Prolific_3_2_0_0

and UV-3R transceiver software that all works FINE on my 

big 64b W7 machine incl Chirp.


Any suggestions on how to solve the W8.1 problems????


The W8.1 Dell Laptop has 3gb ram, 500gb HD and otherwise

runs flawlessly.

Thanks for the answer Tim.

My firmware is BFB297 N5R-20, so it may work... I will try and get back
to the list to report..
