Still a problem with 4.11.0-rc2-ARCH+
4.11-rc2 has better xhci tracing, it shows each URB enqueue and dequeue and
giveback.
Could you try enabling xhci tracing before suspending (not the same as xhci
verbose dynamic debug)
It will generate a lot of data, so better to remove all extra USB devices.
xhci tracing can be added with:
mount -t debugfs none /sys/kernel/debug
echo xhci-hcd >> /sys/kernel/debug/tracing/set_event
and then send the output of cat /sys/kernel/debug/tracing/trace

This is with Linux 4.11.0-rc3-ARCH.
USB mouse/keyboard was unplugged before booting the machine.
I didn't do a suspend/resume before getting this trace, should I do that?
Should I reproduce the hang and get a netconsole dmesg capture with
tracing enabled?
A trace and a dmesg of the same suspend/reusume hang would be great.
And if you can then one of a succesful suspend/resume for reference.
(I haven't yet checked the one you added to bugzilla)
