[TriEmbed] best tool for automagic interaction with USB serial ports

[John Vaughters]

 I have not been able to get the FTDI serial number with "lsusb -v"
This is how I get the serial #
udevadm info --attribute-walk -n /dev/ttyUSB0

it churns out alot of info, but look for 
ATTRS{serial}=="XXXXXXXX" 
X's replaced with serial number.    On Thursday, February 28, 2019, 12:11:50 PM EST, Pete Soper via TriEmbed <triembed at triembed.org> wrote:  
 
  
(Rod Radford sent mail enlightening me with the "-v" option to lsusb that shows per-chip serial numbers for some USB devices and this is why I thanked "guys" instead of just John, as I didn't notice Rod had left out the list.)

 Well I say I will move on from Ubuntu, but I still have it, albeit old. Yet even this old Ubuntu version I have is more current than RedHat (Centos) 7 on libraries. So I still use it. Time will tell if Debian can fully replace Ubuntu. They do a good job of coordinating alot of software. However my hope is Debian does too. Time will tell and I am not in a hurry. Mainly I use Debian for embedded stuff and I have come to really like it. 
   
Well Ubuntu is made out of Debian, just not the stable branch. So in my mind it's already got the high ground. :-) But it gets back to the old saw: You can have it fast, you can have it good, you can have it cheap, pick any two. The stable branch is stable 'cause releases don't happen fast and the extra testing is not cheap. This may be naive, but it seems Ubuntu shares an approach with Microsoft (+/-): why bother with a lot of testing when your users will trip over and report bugs for you? I can say with absolute certainty that this is the attitude TI uses for their tool chain releases for Linux hosts as, on top of a very casual (but commercially clear-eyed) stance they don't even bother to test with up to date versions of Ubuntu! Now when I get hosed by a newly discovered bug in their tools the first thing I do is try it out on a Windows system to avoid wasting time. But to be fair I should repeat that I have never, ever found a code generation error or linker error with the TI tools (and I use the TI compilers as well as gcc). My moans are about host-specific stuff inside Eclipse and some of their probes and other gadgets that have scandalous flaws that don't directly affect the quality of a target system.
