[chirp_users] chirp connecting to UV-5R from Ubuntu 16.04 on Lenovo Carbon X1

Hi,
This is a message Jim sent some time back and I saved it:
Glenn
The #2 cause of trouble for Baofeng radios is the 2-pin plug is not
fully inserted into the speaker/mic socket of the radio. This is
especially common for radios with the GT-3 style case. There is a
raised ridge around the socket well that contacts the plastic shell of
the 2-pin plug which keeps the pins from being fully inserted. The
work around for this is to trim away the part of the plastic shell
that the ridge of the case is interfering with. This page (scroll down
to the GTE section) has pictures of the problem and they show needs to
be done to eliminate the interference (click on the picture to see a
larger version that is easier to see).

Aubrey: Thanks for your response. We have some other software on the laptop that works with 16.04 but seemed to become unstable with Ubuntu 18.04, so I stuck with 16.04. I will try it later with 20.04 when it comes out.
Glenn: Thanks too for your suggestion. Is there any web-page that gives instructions on how to trim the cable properly?
So my current tests have led me to this point:
1) On a fresh reboot of the computer, I plug in the cable. dmesg records:
[ 236.666847] usb 1-2: new full-speed USB device number 6 using xhci_hcd

and we have
$ la /dev/ttyU*
crw-rw---- 1 root dialout 188, 0 Feb 18 09:32 /dev/ttyUSB0
2) I start chirpw and select Download from Radio which fails with
[Errno 16] could not open port /dev/ttyUSB0:
[Errno 16] Device or resource busy: '/dev/ttyUSB0'
dmesg now shows:

[ 313.483329] usb usb1-port2: unable to enumerate USB device
and /dev/ttyUSB0 has disappeared:
$ la /dev/ttyU*
ls: cannot access '/dev/ttyU*': No such file or directory
As an experiment I tried the exact same thing, but only plugging the USB cable into the computer, NOT the radio. This time, on selecting "Download from Radio", chirpw opens the Cloning.... dialog box for a couple of seconds, then reports: Radio did not respond. Furthermore, /dev/ttyUSB0 does not disappear in this situation.
BTW, the firmware on my radio is BFB297. Does that have any bearing on what I'm doing?
Thanks
Kheong.

Just out of curiosity, why did you choose to run such an old distribution (16.04) of Ubuntu on a relatively new laptop?
I just happened to receive a marketing email from Lenovo this morning (I've bought a few PCs from them in the past) that included the Carbon X1 Gen 7 and I looked it up. It has USB 3.1 ports (2x Gen 2 Type-C with Thunderbolt and 2x Gen 1). I'd think that you'd need the latest possible version of Ubuntu (and the Linux kernel) to support this laptop.
Looking at the Ubuntu certification page for the Carbon X1, it shows as having been tested with Ubuntu 18.04 LTS 64-bit.
Your symptoms (device appears, disappears, works sometimes but not others) could be due to instability in the underlying kernel support for the motherboard and/or USB controllers.
Another issue to investigate is the use of USB 3.1 ports. In the past there have been issues with USB 3 ports causing RF interference with devices that are connected. This mostly manifests with wireless keyboards and mice, but it wouldn't surprise me if it was an issue here. The common fix is to use a USB extension cable to move the USB device away from the port.

I had connected the cable, tried to access it from chirpw causing it to disconnect a few times, by the time I did dmesg. I removed out the multiple connect/disconnect lines from dmesg output because the information was mostly duplicate.

Just double checking here. The log messages below show the cable connecting, and then disconnecting. Had you disconnected the cable again before running dmesg, or did the cable fail?
