I’ve installed the drivers as suggested and tested that the device is present using the
kexstat | grep prolific
ioreg -c IOSerialBSDClient | grep usb
and I can see the device.
Trouble is I still can’t communicate with the GPS. I get an error message from GPS Babel saying:
ERROR] GPS_Packet_Read: Timeout. No data received.
GARMIN:Can’t init /dev/cu.usbserial
I realise this isn’t a GPS forum but any idea if it’s likely to be the GPS or the serial adapter?
Interestingly I can connect to the GPS using the serial adapter if I run Windows XP as a virtual machine in VMWare fusion. It’s kind of a clunky way of doing what I want to do and I’d really like to have it working directly through the Mac OS.
I’m running OS X 10.8.2
Any help would be greatly appreciated.
