Eclipse ThreadX USBX 6.4.5.202504a

This is a hotfix release fixing code issues that prevented our full regression tests from running.

Important notice about version numbers

In the past, new versions of ThreadX and its companion components (NextX Duo, USBX, FileX, GUIX, LevelX) were published only when there were changes to the codebase. This led to discrepancies in version numbers across components. The Eclipse Foundation security team recommended that we move away from this approach, as it makes it harder to track things from a cybersecurity standpoint.

Going forward, we will keep version numbers aligned by publishing a new version of every component every quarter — whether there have been changes to the codebase or not. The release notes will clearly state if a specific release is simply a version number update.

What's Changed

• Fix CI build issue by @ayedm1 in #241

Eclipse ThreadX USBX 6.4.5.202504

This release delivers specific HID improvements and solves a compilation issue when the library is used in standalone mode.

For this particular release of USBX, the version number jumped from v.6.4.3 to v.6.4.5 to catch up with NetX Duo.
