Wow Imperia, you're being really helpful here, thank you very much!

To enable traces, these are the instructions I've provided to other people affected so far:

0) Reboot the machine in order to put it in a consistent state;
1) echo "module xhci_hcd +flpt" > /sys/kernel/debug/dynamic_debug/control
2) echo nop > /sys/kernel/debug/tracing/current_tracer
3) echo 81920 > /sys/kernel/debug/tracing/buffer_size_kb
4) echo 0 > /sys/kernel/debug/tracing/trace
5) echo 1 > /sys/kernel/debug/tracing/tracing_on
6) echo 1 > /sys/kernel/debug/tracing/events/xhci-hcd/enable

After reproduce the issue, you should collect /sys/kernel/debug/tracing/trace. Problem is that the file might be huge, much larger than the kernel log you provided for instance.

About the SSH access, I'm interested in getting it next week, if it doesn't annoy you too much. It'll be really helpful, but I might need to reboot the machine.

Oh, I've downloaded the logs from your website, so you can delete it now.
Cheers,

Guilherme
