From: AceLan Kao Date: Wed, 2 Oct 2013 09:35:26 +0000 (+0800) Subject: HID: usbhid: quirk for Synaptics Large Touchccreen X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8171a67d587a09e14a4949a81e070345fedcf410;p=linux-beck.git HID: usbhid: quirk for Synaptics Large Touchccreen BugLink: http://bugs.launchpad.net/bugs/1180881 Synaptics large touchscreen doesn't support some of the report request while initializing. The unspoorted request will make the device unreachable, and will lead to the following usb_submit_urb() function call timeout. So, add the IDs into HID_QUIRK_NO_INIT_REPORTS quirk.
