Summary
Fixes LIBUSB_ERROR_ACCESS errors caused by concurrent USB operations (preset polling, disconnect checks, user actions) racing to claim the interface. Routes all access through a shared cached DeviceClient guarded by a mutex, with cache invalidation on error so the next call reconnects cleanly.
