Subject: Re: [PATCH RFC 1/1] usb: Tell xhci when usb data might be misaligned
Date: Thu, 30 Jan 2014 16:42:30 -0500 [thread overview]
Message-ID: <52EAC746.1030102@pobox.com> (raw)
In-Reply-To: <52EAC696.6050708@pobox.com>
Sarah, on a related note:
Is there a parameter or knob of some kind to tell the XHCI driver
to treat a specific port as USB2 (480mbit/sec max) rather than USB3 ?
The Dell XPS-13 Ultrabooks all suffer from some kind of flaw, whereby the left side
USB3 port is unreliable at SuperSpeed; the right side port works flawlessly.
The MS-Windows driver has a workaround of some sort, but we don't.
Cheers
