+Subject: [PATCH] xhci: Disable streams on Via XHCI with device-id 0x3432
+
+This is a bit bigger hammer then I would like to use for this, but for now
+it will have to make do. I'm working on getting my hands on one of these so
+that I can try to get streams to work (with a quirk flag if necessary) and
+then we can re-enable them.
+
+For now this at least makes uas capable disk enclosures work again by forcing
+fallback to the usb-storage driver.
