Different computer but same cables i guess the device is ok.

NTL I found that little gem:
https://www.fclose.com/linux-kernels/594677/usb-io_ti-add-heartbeat-to-keep-idle-ep-416-ports-from-disconnecting-linux-4-3/

The behavior would fit (any way to check that the heartbeat is active ?).

Casten Schmidt ask me to look into /sys/kernel/debug/dynamic_debug/control before i start to
debug the whole usb part, is that below expected behavior ? (i tried to find what version of edgeport the driver suspects).

Which kernel are you running on?
use "uname -a" to get it.
This patch was introduced in 4.3 kernel, not really hot ...
And, yes, looks like what you experience.

That says that we have dynamic debug messages available for the driver.
If you enable those by doing
echo -n 'module io_ti =p' > /sys/kernel/debug/dynamic_debug/control

Then you should see at least some of those messages appear in dmesg (kernel log).

mea culpa, i had a typo in the first msg to greg so you did not see my first post:

I tested with: Opensuse 15.1 on a DELL latitude E5400

 uname -a
 Linux omnfrmo10 4.12.14-lp151.28.10-vanilla #1 SMP Sat Jul 13 17:59:31 UTC 2019 (0ab03b7) x86_64 x86_64 x86_64 GNU/Linux

 I did some experiments (changing cables etc) but always the same. But
 when tested with a windows system it worked all fine.  later i used a
 single port USB->Serial and all worked as expected.

The dyndbg for the driver is active :-)

The log you sent does not show something irregular.
Can you collect the log "around a device reset" in the same way please?

Just to close the problem:
I have installed the  Edgeport/416 on a different pc

Linux  4.12.14-lp150.12.25-default #1 SMP Thu Nov 1 06:14:23 UTC 2018 (3fcf457) x86_64 x86_64 x86_64 GNU/Linux
With opensuse 15.0

the one with the problem was:
Linux  4.12.14-lp151.28.10-vanilla #1 SMP Sat Jul 13 17:59:31 UTC 2019 (0ab03b7) x86_64 x86_64 x86_64 GNU/Linux


the far the device works as expected (to my surprise). So it seems to be a broken USB, why it fails
with the edgeport but not with the pl2303 (usb->rs232 someone) i used for comparison; no idea.

sorry for the noise,

So the device works, but the connection to your other computer probably
does not.  I'm betting this is an electrical issue :)

problems with Edgeport/416

[walter harms]

Hello List,
does some use linux with an Edgeport/416 ?

I have a strange problem. the device is resetting soon
after i started using it (but not immediately).
I do not see a kernel OOPS but a common pattern is:

I did some experiments (changing cables etc) but always the same. But when tested with a windows system it worked all fine.
later i used a single port USB->Serial and all worked as expected.

I tested with: Opensuse 15.1 on a DELL latitude E5400

uname -a
Linux omnfrmo10 4.12.14-lp151.28.10-vanilla #1 SMP Sat Jul 13 17:59:31 UTC 2019 (0ab03b7) x86_64 x86_64 x86_64 GNU/Linux

I would like to improve the situation, does anyone has that device ? any hints what to look at ?

please reply direct, i am not member of this list.

AW: problems with Edgeport/416

[Schmid, Carsten]

Hi Walter,

i had a similar issue with a different device.
Please check, if you have dynamic debug enabled in your kernel
(/sys/kernel/debug/dynamic_debug/control exists)

Then you can enable additional kernel messages using
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'module usbcore =p' > /sys/kernel/debug/dynamic_debug/control

Check which usb related messages you can enable through the dynamic_debug.
(doing a "cat /sys/kernel/debug/dynamic_debug/control | grep usb" helps much)

Finally, a fine resource is
https://www.kernel.org/doc/html/v4.11/admin-guide/dynamic-debug-howto.html

Best regards
Carsten

I see a bunch of messages. what do you expect me to do ? I have 412 lines, should
i send them ?
