CHIRP

Hi,

I'm able to download the configuration from the BTech UV-2501+220 radio using CHIRP-daily (current as of 20160507) under Windows 10, but it fails with "An error has occurred" / "Invalid header for bloxk 0x000:" using Linux Mint.

Salient points:

• FTDI data cable obtained from BTech
• /dev/ttyUSB0 in Linux (read-write permissions fine); COM3 in Windows
