From bfe3c873e978d78b542a5852575dd74f4d1a5838 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 5 Sep 2014 18:08:48 +0200 Subject: HID: usbhid: enable always-poll quirk for Elan Touchscreen Enable the always-poll quirk for Elan Touchscreens found on some recent Samsung laptops. Without this quirk the device keeps disconnecting from the bus (and is re-enumerated) unless opened (and kept open, should an input event occur). Note that while the device can be run-time suspended, the autosuspend timeout must be high enough to allow the device to be polled at least once before being suspended. Specifically, using autosuspend_delay_ms=0 will still cause the device to disconnect on input events.
