CHIRP

I have a Valley Enterprises FTDI cable and trying to use with Yaesu-FT90R.

After I selected my model radio and port /

dev/cu.usbserial-A105ZGRL

Failed to communicate with radio: Traceback (most recent call last):
File "/Applications/chirp-daily-20180512.app/Contents/Resources/chirp/chirp/drivers/ft90.py", line 332, in sync_in

(blocknum, blocksize+2, len(data)))
Exception: Unable to read blocknum 00 expected blocksize 4 got 0.

I installed the latest signed 2.4.2 Drivers https://www.valley-ent.com/store/ftdi-usb-vcp-driver.html which linked to http://www.ftdichip.com/Drivers/VCP.htm
