Debian 10’s /boot/config-4.19.0-6-amd64 has # USB HID Boot Protocol drivers # # CONFIG_USB_KBD is not set # CONFIG_USB_MOUSE is not set while Guix has in /tmp/guix-build-linux-libre-5.4.32.drv-0/linux-5.4.32/.config CONFIG_USB_MOUSE=m I will write and test a patch to disable the module in %default-extra-linux-options, like the description in linux-5.4.11 source file drivers/hid/usbhid/Kconfig recommends: config USB_MOUSE tristate "USB HIDBP Mouse (simple Boot) support" depends on USB && INPUT ---help--- Say Y here only if you are absolutely sure that you don't want to use the generic HID driver for your USB mouse and prefer to use the mouse in its limited Boot Protocol mode instead. This is almost certainly not what you want. This is mostly useful for embedded applications or simple mice. To compile this driver as a module, choose M here: the module will be called usbmouse. If even remotely unsure, say N. Regards, Florian
