+Subject: USB: core: add device-qualifier quirk
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+commit 2a159389bf5d962359349a76827b2f683276a1c7 upstream.
+
+Add new quirk for devices that cannot handle requests for the
+device_qualifier descriptor.
+
+A USB-2.0 compliant device must respond to requests for the
+device_qualifier descriptor (even if it's with a request error), but at
+least one device is known to misbehave after such a request.

+
+commit 876af5d454548be40327ba9efea4bc92a8575019 upstream.
+
+Currently this quirk is enabled for the model with the device id 0x0089, it
+is needed for the 0x009b model, which is found on the Fujitsu Lifebook u904
+as well.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit c68929f75dfcb6354918862b91b5778585de1fa5 upstream.
+
+Enable device-qualifier quirk for Elan Touchscreen, which often fails to
+handle requests for the device_descriptor.
+
+Note that the device sometimes do respond properly with a Request Error
+(three times as USB core retries), but usually fails to respond at all.
+When this happens any further descriptor requests also fails, for
+example:
+
+[ 1528.688934] usb 2-7: new full-speed USB device number 4 using xhci_hcd
+[ 1530.945588] usb 2-7: unable to read config index 0 descriptor/start: -71
+[ 1530.945592] usb 2-7: can't read configurations, error -71
+
+This has been observed repeating for over a minute before eventual
+successful enumeration.
