[chirp_users] radio won't ack first command error

ok, I got the port permissions issue resolved (its a bug in the initial system setup and I wasn't added to dial out).

However, now I have this problem: radio: PX-777 vendor: puxingradio port: /dev/ttysusb0

downloading profile from radio… error: radio did not ACK first command.

ok, so how do I get around this?

The version of chirp I am using is on uBuntu 13.04 and I don't get have a development environment setup. do I have to get one of the daily builds to make this work?
