>Subject: [PATCH 2/3] USB: quirks: enable device-qualifier quirk for Elan
> Touchscreen
>
>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.
