Subject: [PATCH 4.9 43/66] HID: usbhid: Quirk a AMI virtual mouse and keyboard with ALWAYS_POLL
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@...onical.com>
commit ed9ab4287f96e66340e0390e2c583f2f9110cba0 upstream.
Quirking the following AMI USB device with ALWAYS_POLL fixes an AMI
virtual keyboard and mouse from not responding and timing out when
it is attached to a ppc64el Power 8 system and when we have some
rapid open/closes on the mouse device.
usb 1-3: new high-speed USB device number 2 using xhci_hcd
usb 1-3: New USB device found, idVendor=046b, idProduct=ff01
usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-3: Product: Virtual Hub
usb 1-3: Manufacturer: American Megatrends Inc.

With the quirk I have not been able to trigger the issue with
half an hour of saturation soak testing.
