[chirp_users] Baofeng UV-5R Just transmits when connected to computer

Ubuntu does it.

Get your copy of Ubuntu and make a "tail -f /var/log/syslog" on a 
terminal to watch out for hardware changes...

now Plug any USB-serial adapter in the box... you will see modem-manager 
happily testing it and complain about it not being a modem... some 
devices are on time and in less than 5 seconds it complains and leave it 
alone

Others are lazy/slow and may take a few seconds (My USB-Serial adapter 
for other project {ark3##? chipset} can be also a RS-485 device so the 
kernel takes its time to probe if it's a RS232 or RS485 < I'm no sure if 
this is the other correct standard number...) and may take up to 10 to 
15 seconds to release the serial port...

I use to kill and remove modem manager when this is an issue for 
productivity/speed on the development... but this bug may bite you... so 
be warned.

Cheers.
