(Note: initially sent to linux-kernel, sorry about that) Hi, I am trying to use the keyboard I mentioned. Most of the keys work fine, except for Shift/Alt/Ctrl/Win. All of them are mapped a left shift. Some notes: 1. dmesg output when plugging in the keyboard [185765.848957] input: USB Keyboard as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/0003:0C45:760B.0022/input/input50 [185765.905395] hid-generic 0003:0C45:760B.0022: input,hidraw3: USB HID v1.11 Keyboard [USB Keyboard] on usb-0000:00:14.0-3/input0 [185765.949342] input: USB Keyboard as Fwd: Redragon Asura Keyboard - All Shift, Ctrl, Alt, Win keys function as left shift/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.1/0003:0C45:760B.0023/input/input51 [185766.009474] hid-generic 0003:0C45:760B.0023: input,hiddev0,hidraw4: USB HID v1.11 Keyboard [USB Keyboard] on usb-0000:00:14.0-3/input1 The first input device sends absolutely no input, the second one sends all the input. 2. Tests done using evtest With evtest, all the mentioned keys have the following output: Event: time 1497272760.897616, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e1 Event: time 1497272760.897616, type 1 (EV_KEY), code 42 (KEY_LEFTSHIFT), value 1 3. Information from debugs In sys/kernel/debug/hid I have two entries: - 0003:0C45:760B.0037 - 0003:0C45:760B.0038 I've pasted the rdesc output at - https://pastebin.com/4VwDKRvU - https://pastebin.com/CrBVRFBj 4. Hexdump output I've taken the hexdump output when pressing the affected keys. The keypresses, in order, were: - Left Shift - Left Ctrl - Win - Left Alt - Right Alt - Right Ctrl - Right Shift 00000000 04 00 00 00 00 00 00 00 04 02 00 00 00 00 00 00 |................| 00000010 04 00 00 00 00 00 00 00 04 01 00 00 00 00 00 00 |................| 00000020 04 00 00 00 00 00 00 00 04 08 00 00 00 00 00 00 |................| 00000030 04 00 00 00 00 00 00 00 04 04 00 00 00 00 00 00 |................| 00000040 04 00 00 00 00 00 00 00 04 40 00 00 00 00 00 00 |.........@......| 00000050 04 00 00 00 00 00 00 00 04 10 00 00 00 00 00 00 |................| 00000060 04 00 00 00 00 00 00 00 04 20 00 00 00 00 00 00 |......... ......| If you need more information to qualify whether this is a bug or not, let me know. I'd be glad to test any potential fixes. I am running kernel 4.11.2 ( openSUSE Tumbleweed x86_64 ).
