AW: problems with Edgeport/416

["Schmid, Carsten" <Carsten_Schmid@mentor.com>]

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
