HID: huawei: fix CD30 keyboard report descriptor issue

2026-04-09T15:56:46Z

When the Huawei CD30 USB keyboard undergoes 500 reboot cycles, initialization may fail due to a report descriptor problem. The error log is as follows: [pid:175,cpu0,kworker/0:1,6]usb 1-1.2.2: new low-speed USB device number 6 using xhci-hcd [pid:175,cpu0,kworker/0:1,9]usb 1-1.2.2: New USB device found, idVendor=12d1, idProduct=109b, bcdDevice= 1.03 [pid:175,cpu0,kworker/0:1,0]usb 1-1.2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [pid:175,cpu0,kworker/0:1,1]usb 1-1.2.2: Product: HUAWEI USB Wired Keyboard [pid:175,cpu0,kworker/0:1,2]usb 1-1.2.2: Manufacturer: HUAWEI [pid:175,cpu0,kworker/0:1,4]input: HUAWEI HUAWEI USB Wired Keyboard as /devices/platform/efc00000.hisi_usb/efc00000.dwc3/xhci-hcd.1.auto/usb1/1-1/1-1.2/1-1.2.2/1-1.2.2:1.0/0003:12D1:109B.0002/input/input6 [pid:175,cpu0,kworker/0:1,5]hid-generic 0003:12D1:109B.0002: input,hidraw1: USB HID v1.10 Keyboard [HUAWEI HUAWEI USB Wired Keyboard] on usb-xhci-hcd.1.auto-1.2.2/input0 [pid:175,cpu0,kworker/0:1,9]hid-generic 0003:12D1:109B.0003: collection stack underflow [pid:175,cpu0,kworker/0:1,0]hid-generic 0003:12D1:109B.0003: item 0 0 0 12 parsing failed [pid:175,cpu0,kworker/0:1,1]hid-generic: probe of 0003:12D1:109B.0003 failed with error -22 ...

HID: drop 'default !EXPERT' from tristate symbols

2026-04-09T15:53:26Z

There is no reason to build random drivers for obscure hardware into the core kernel by default. The usages of 'default !EXPERT' for the HID_PICOLCD suboptions are kept, as these make some sense, although they probably should use 'default y'.

HID: hid-lenovo-go: fix LEDS dependencies

2026-03-27T10:54:08Z

The newly added hid-lenovo-go and hid-lenovo-go-s drivers attempt to 'select LEDS_CLASS', which has a dependency on NEW_LEDS, causing a build failure when NEW_LEDS itself it disabled: WARNING: unmet direct dependencies detected for LEDS_CLASS Depends on [n]: NEW_LEDS [=n] Selected by [m]: - HID_LENOVO_GO [=m] && HID_SUPPORT [=y] && HID [=m] && USB_HID [=m] - HID_LENOVO_GO_S [=m] && HID_SUPPORT [=y] && HID [=m] && USB_HID [=m] WARNING: unmet direct dependencies detected for LEDS_CLASS_MULTICOLOR Depends on [n]: NEW_LEDS [=n] && LEDS_CLASS [=m] Selected by [m]: - HID_LENOVO_GO [=m] && HID_SUPPORT [=y] && HID [=m] && USB_HID [=m] - HID_LENOVO_GO_S [=m] && HID_SUPPORT [=y] && HID [=m] && USB_HID [=m] ERROR: modpost: "led_set_brightness_nopm" [drivers/leds/led-class.ko] undefined!

ERROR: modpost: "led_set_brightness" [drivers/leds/led-class-multicolor.ko] undefined! Device drivers generally should not select other subsystems like this, as that tends to cause dependency problems including loops in the dependency graph. Change these two and the older hid-lenovo driver to behave the same way as all other HID drivers and use 'depends on LEDS_CLASS' or 'depends on LEDS_CLASS_MULTICOLOR' instead, which itself has NEW_LEDS and LEDS_CLASS as dependencies.

HID: hid-lenovo-go-s: Add Lenovo Legion Go S Series HID Driver

2026-03-10T16:53:17Z

Adds initial framework for a new HID driver, hid-lenovo-go-s, along with a uevent to report the firmware version for the MCU. This driver primarily provides access to the configurable settings of the Lenovo Legion Go S controller. It will attach if the controller is in xinput or dinput mode. Non-configuration raw reports are forwarded to ensure the other endpoints continue to function as normal.

HID: hid-lenovo-go: Add Lenovo Legion Go Series HID Driver

2026-03-10T16:53:16Z

Adds initial framework for a new HID driver, hid-lenovo-go, along with attributes that report the firmware and hardware version for each component of the HID device, of which there are 4 parts: The MCU, the transmission dongle, the left "handle" controller half, and the right "handle" controller half. Each of these devices are provided an attribute group to contain its device specific attributes. Additionally, the touchpad device attributes are logically separated from the other components in another attribute group. This driver primarily provides access to the configurable settings of the Lenovo Legion Go and Lenovo Legion Go 2 controllers running the latest firmware. As previously noted, the Legion Go controllers recently had a firmware update[1] which switched from the original "SepentiaUSB" protocol to a brand new protocol for the Go 2, primarily to ensure backwards and forwards compatibility between the Go and Go 2 devices. As part of that update the PIDs for the controllers were changed, so there is no risk of this driver attaching to controller firmware that it doesn't support. -- v6: - Make attributes static. - Use NULL instead of 0 in mcu_propery_out when there is no data. v5: - Make version attributes static, retrieve them using delayed work during probe. - Fix endianness of version strings and print as hex. v3: - Add hid-lenovo.c and Mark Pearson to LENOVO HID DRIVERS entry in MAINTAINERS Reviewed-by: Mark Pearson Signed-off-by: Derek J.
