Daniel Samson 7ee6033fa4 usb-hid: echo typed characters to the log — a simple keyboard check ... There was no way to confirm a keyboard actually registers keys on real hardware (enumeration binding the driver only proves the device came up). The keyboard driver now echoes each decoded printable character (and newline) to its log: type a known phrase and read it back from usb-hid-keyboard.log, or watch it appear live on screen in a -Ddiagnose boot (where the kernel console is a log sink). It exercises the whole path — HID report -> diff -> layout -> character — not just enumeration, and works identically for a keyboard behind a hub. A usb-key-echo QEMU case injects a phrase via QMP send-key and asserts it echoes (stable across repeated runs). Full suite 92/92.		2026-07-21 22:27:47 +01:00
