linux-toradex.git/drivers/hid/hid-speedlink.c, branch v3.16.6 Linux kernel for Apalis and Colibri modules HID: Fix Speedlink VAD Cezanne support for some devices 2013-08-26T11:51:10+00:00 Stefan Kriwanek dev@stefankriwanek.de 2013-08-25T08:46:13+00:00 06bb5219118fb098f4b0c7dcb484b28a52bf1c14 Some devices of the "Speedlink VAD Cezanne" model need more aggressive fixing than already done. I made sure through testing that this patch would not interfere with the proper working of a device that is bug-free. (The driver drops EV_REL events with abs(val) >= 256, which are not achievable even on the highest laser resolution hardware setting.)

HID: Use module_hid_driver macro 2013-01-03T09:27:31+00:00 H Hartley Sweeten hartleys@visionengravers.com 2012-12-17T22:28:26+00:00 f425458eafd51b6b5ab64f407922e1198c567cb2 Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.

HID: Add driver to fix Speedlink VAD Cezanne support 2011-06-08T07:45:37+00:00 Stefan Kriwanek mail@stefankriwanek.de 2011-05-27T16:40:29+00:00 74bc6953135ae1478acc18046321bfca05b0e823 Speedlink VAD Cezanne have a hardware bug that makes the cursor "jump" from one place to another every now and then. The issue are relative motion events erroneously reported by the device, each having a distance value of +256. This 256 can in fact never occur due to real motion, therefore those events can safely be ignored. The driver also drops useless EV_REL events with a value of 0, that the device sends every time it sends an "real" EV_REL or EV_KEY event.
