Windows export now reports the real USB link speed, probed from the
parent hub (IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX and _V2 for
SuperSpeedPlus), so SuperSpeed devices route to the correct root-hub
speed domain instead of advertising speed=0.
- protocol: pin DeviceInfoTruncated/DeviceInterface wire sizes with
two-sided compile-time assertions so a struct change fails the build
instead of silently mis-bounding the reader
- server: bound inbound connections with a handshake read deadline and a
per-iteration idle deadline on the control loop, plus write deadlines
on control writes; clear the deadline before the conn becomes a data
session
- server: serialize import reservation under reconcileAccess so a reserve
cannot interleave a reconcile pass that would release a busy device
- data: validate CMD_SUBMIT iso descriptor offset/length against the
transfer buffer before forwarding to a platform engine
- darwin: make darwinUSBHostDevice.Close idempotent via sync.Once to
avoid a double close/free under concurrent shutdown
- windows: guard windowsExport.device with a mutex and hand the claimed
handle to a single closer
The VBoxUSB.sys / VBoxUSBMon.sys / .inf / .cat binaries copied from
dorssel/usbipd-win Drivers/{x64,arm64}/ ship paired SPDX
*.license files that record Oracle's GPL-3.0-only copyright. Carrying
them next to the assets keeps the provenance discoverable.
Both the existing darwin backend and the upcoming windows backend
drive USB devices from user space (IOUSBHost CGO calls vs. VBoxUSB
IOCTLs). Refactor the per-attachment URB loop out of host_darwin.go
into a platform-agnostic userspaceURBSession that talks to a URBEngine
interface; the darwin-specific dispatch becomes a 30-line
darwinIOUSBHostEngine. Linux's kernelHandoffSession is untouched.
Move hex8 into shared.go and add usbipStatusEIO so the shared session
does not depend on golang.org/x/sys/unix (Windows has no equivalent).
