Do you have the beginning part of the dmesg? It could show why the USB
devices all get disconnected.
The whole xhci usb host will be hotplug removed from the PCI bus when
last device is disconnected, this
is roughly where your current dmesg starts.
There's nothing in the dmesg for many minutes before what I sent.
Also adding xhci, and usb core dynamic debug could help:
mount -t debugfs none /sys/kernel/debug
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control
Noted. Will give them a go and try to reproduce.
