<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi Alvin,<br><br>Forgive me if you know all of this already: <br>Linux allocates and removes the ttyUSB devices "on the fly" as they are inserted or removed. It usually adds them, in order of insertion, as ttyUSB0, ttyUSB1, etc. regardless of which USB connector they are plugged into. At least that's been my experience with the Ubuntu and Fedora distributions. I find it's very easy to get the ttyUSBx devices mixed up if you have more than one, especially when troubleshooting a problem. An example, FWIW:<br><br>If you:<br>1. You plug in a USB serial device. Linux adds it as ttyUSB0<br>2. You start an application (let's use chirp for this example).<br>3. Chirp sees the device as ttyUSB0 and opens it.<br>4. The device appears to get "hung" for one reason or another.<br>4. The USB adapter is unplugged, then reinserted.<br>5. Linux makes the same USB adapter
be ttyUSB1 this time because Linux thinks ttyUSB0 is still in use as far as Linux knows.<br><br>That's why I usually run:<br>dmesg | grep ttyUSB<br>when I remove or insert USB serial adapters to verify what ttyUSB device Linux thinks it is. <br><br>Do this before you start chirp so you know you've selected the correct USB device. If you only have one USB serial adapter it should be the only ttyUSB device chirp lists in the selection menu.<br><br>Happy testing!<br>Mike, N0SO (using a real keyboard this time)<br><br><br><br><br>--- On <b>Tue, 6/7/11, Alvin <span>Koffman</span> <i><ka9qlq@gmail.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Alvin Koffman <ka9qlq@gmail.com><br>Subject: Re: [chirp_users] Dumb 8900 queary<br>To: "Discussion of CHIRP" <chirp_users@intrepid.danplanet.com><br>Date: Tuesday, June 7, 2011, 4:06 AM<br><br><div

CHIRP against both of them?<br>
