[chirp_users] Yosemite - SiLABS UART

Using Yosemite on iMac. Had the SiLabs and Yaesu FT-1D with SCU-19 cable working ok. Took a long time and should have written the procedure.

I installed the Prolific drive for Baofeng radio. I got that working OK. Then the SiLABS UART stopped ’talking’ to Yaesu. Using latest daily build of Chirp.

Looking at info on mac, I see the drivers for both Prolific and UART under USB selection

Anyone have any ideas - I have re-installed the UART driver. I can see various selection when I connect CHIRP under Ports. Both the SLAB_USB-UART and USB-Prolific show up.

I have also used the command under terminal: sudo nvram boot-args="kext-dev-mode=1”

I am not very savvy on Mac but need help suggestions???
