From 35cfd1d964f3c2420862f2167a0eb85ff1208999 Mon Sep 17 00:00:00 2001 From: Michael Tokarev Date: Sun, 1 Feb 2009 16:11:04 +0100 Subject: [PATCH 1/4] HID: blacklist Powercom USB UPS For quite some time users with various UPSes from Powercom were forced to play magic with bind/unbind in /sys in order to be able to see the UPSes. The beasts does not work as HID devices, even if claims to do so. cypress_m8 driver works with the devices instead, creating a normal serial port with which normal UPS controlling software works. The manufacturer confirmed the upcoming models with proper HID support will have different device IDs. In any way, it's wrong to have two completely different modules for one device in kernel. Blacklist the device in HID (add it to hid_ignore_list) to stop this mess, finally.
