xhci driver doesn't yet have tracing for stream contexts, I started writing those but didn't finish them yet.
A set of tracing and debugging patches for this is now available in my fix_uas_babble_error branch git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git fix_uas_babble_error https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=fix_uas_babble_error Much appreciated if you have the time to try them out. This time I think we should enable _all_ xhci traces. The trace file might grow fast but it would be good to get traces starting before the uas device is connected. Updated steps: mount -t tracefs none /sys/kernel/tracing/ echo 81920 > /sys/kernel/tracing/buffer_size_kb echo 1 > /sys/kernel/tracing/events/xhci-hcd/enable echo 1 > /sys/kernel/tracing/tracing_on <connect uas device> <trigger issue> send content of /sys/kernel/tracing/trace and dmesg to me Thanks Mathias
