From 5e1bdc12bd298a9751da4285b7e93c68b1314332 Mon Sep 17 00:00:00 2001 From: salmonik Date: Tue, 4 Aug 2026 03:06:06 +0200 Subject: v0.5.10: USB HID mouse via polled xHCI (rsnix/src/usb.rs) Polled xHCI driver (mouse-only): controller bring-up, port reset, enable-slot -> address-device -> config-descriptor walk -> HID boot mouse IN endpoint, one outstanding IN TRB drained on poll. Cursor task polls usb first, PS/2 second. New 'usb'/'usb rescan' shell cmds. Verified in QEMU (q35 + OVMF + qemu-xhci + usb-mouse): movement and all three buttons tracked exactly; heap stays clean.
