* Initial commit for USB Mass Storage Support * Add support for SCSI_16 and various fixes by debrouxl * Fix USB HCD registration to skip failed probes (when a mass storage device was already found) * Fix xHCI bulk transfer completion matching & accept short packets for IN transfers * Add USB BOT error recovery and match xHCI control events by slot/EP * Add EHCI bulk timeout/size guard, fix per-controller MSD port handling, and make xHCI keyboard re-arm precise * Harden FAT/GPT parsing (cluster validation & block-size check) and fix RTC read issue due to R/W race * Fix report varargs on x86_64, truncate F6 drive label, and clean up failed FAT file writes * Fix stale hub VID/PID read, refactor USB MSD detection to helper & tidy usbhcd/display/config layout * Scan for USB drives on demand when saving a report Keep EHCI/xHCI controllers registered when empty and rescan free root ports on F6. Also fix xHCI keyboard re-arm losing a key release, dropping the next same-key press.
