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.

modem daemon. Do you mean Network Manager, or do you mean pppd? Unless very specifically configured to do SLIP or PPP, Network Manager shouldn't probe any devices at all to see if they are a modem. If they did, it would power-off any APC UPS plugged into a serial port instantly.

I little trick I learned from experience:
Ubuntu has a deamon for handling modems, if you try to plug your USB cable and read/write to the radio at the same moment you usually get an error because the modem daemon is testing it to know if that USB-serial is a modem...
If you use Ubuntu or any of his favors just plug your USB without the radio connected and wait 10 to 30 seconds before connecting your radio an try to read/write to it, in this way the modem daemon got plenty of time to test it and discard it as a modem and let it free for you.

I have a machine running Ubuntu Mate. When I connect and turn on my Baofeng UV-5R radio it will transmit and will not let me use Chirp. I also have a Windows 7 computer that does the same thing. Any help would be appreciated.
