  "message": "HID: cypress: Support Varmilo Keyboards\u0027 media hotkeys\n\n[ Upstream commit 652f3d00de523a17b0cebe7b90debccf13aa8c31 ]\n\nThe Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M)\nexposes media control hotkeys as a USB HID consumer control device, but\nthese keys do not work in the current (5.8-rc1) kernel due to the\nincorrect HID report descriptor. Fix the problem by modifying the\ninternal HID report descriptor.\n\nMore specifically, the keyboard report descriptor specifies the\nlogical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage\nboundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an\nincorrect interpretation of input reports, causing inputs to be ignored.\nBy setting the Logical Minimum to zero, we align the logical boundary\nwith the Usage ID boundary.\n\nSome notes:\n\n* There seem to be multiple variants of the VA104M keyboard. This\n  patch specifically targets 04b4:07b1 variant.\n\n* The device works out-of-the-box on Windows platform with the generic\n  consumer control device driver (hidserv.inf). This suggests that\n  Windows either ignores the Logical Minimum/Logical Maximum or\n  interprets the Usage ID assignment differently from the linux\n  implementation; Maybe there are other devices out there that only\n  works on Windows due to this problem?\n\nSigned-off-by: Frank Yang \u003cpuilp0502@gmail.com\u003e\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\nSigned-off-by: Sasha Levin \u003csashal@kernel.org\u003e\n",
