is has the added benefit of removing the periodic control requests to the
iOS device until trust has been established and thus should reduce wakeup
events on both the host and the iOS device.

xes this issue by storing a pointer to the xhci_ring
field in the xhci device structure in debugfs rather than directly
storing a pointer to the xhci_ring.

Hi Mathias,
thanks for the patch! The system now resumes cleanly from hibernate even
with usbmuxd doing its thing.

While testing this I hit some other issues with xhci-debugfs.c but I'll
write these up in a separate bug.

The ALWAYS_SYNC flag is currently honored by the usb-storage driver but not UAS
and is required to work around devices that become unstable upon being
queried for cache. This code is taken straight from:

v2 of this patch implements the FL_ALWAYS_SYNC flag in the UAS driver, and then
adds the flag as quirks for the device at issue. This allows the G-Drive to work
under both UAS and usb-storage.

n unusual_uas.h that currently have all UAS
support disabled. I'd be happy to write the patch, but I'm not sure we want
to reserve a quirk bit for what's currently only a single device known to
have this issue. Please advise.

I've seen similar issues caused by USB persist. Try disabling it (echo 0 >
/sys/bus/usb/devices//power/persist), and then resuming.
