If the queue is empty we need the check here.
Added ports for RXv1/GNU, RXv2/GNU and RXv3/GNU
- Add mass-storage “removable media” support by tracking per-LUN prevent/allow medium removal and loaded/ejected status.
- Introduce an optional per-LUN callback to handle SCSI START STOP UNIT (including load/eject and power-condition fields).
- Extend storage constants (media types, sense keys/codes, power conditions, prevent flags) to support the new behavior and improve readability (explicit hex values).
- Initialize new per-LUN state on activation (default: medium removal allowed, medium loaded) and wire the new callback through storage initialization.
- Includes minor formatting/comment cleanups and version banner updates to 6.4.6.

SCSI Block Commands – 4 (SBC-4)
- Adds _ux_dcd_sim_slave_uninitialize() to free the simulated slave DCD controller instance, clear DCD bindings, and return the DCD to UX_UNUSED (idempotent if already unused).
- Registers the new uninitialize source in CMakeLists.txt.
- Updates simulator headers to export ux_dcd_sim_slave_uninitialize (and ux_hcd_sim_host_uninitialize) and does minor whitespace/style cleanup in the simulator header blocks.
- Implements handling of UX_SLAVE_CLASS_CDC_ACM_SEND_BREAK in the CDC ACM control request path.
- Ensures break state is cleared on class deactivation to avoid carrying state across disconnect/reset cycles.
- Minor comment/whitespace cleanups in touched headers/sources.
- Testing: Build-only / compilation sanity/send break request. (no new automated tests added).
Added a check for NULL packet before using the pointer
When compiling with UX_ENABLE_DEBUG_LOG the call to
_ux_utility_memory_allocate requires the system mutex.
…re_memory_allocation

Modified logic to create mutex before calling _ux_utility_memory_allocate
Added uninitialize API to the DCD Simulator Controller Driver
Fixed Linux enumeration for device RNDIS
Added START STOP (load/eject) request support to Device MSC
Improved code to leverage the ux internal macros instead of using direct tx struct fields
Updated copyright headers and version number constants
Pre v6.5.0.202601 fixes
Added break request support to Device CDC ACM
