Detailed Description

USB Bluetooth (class 0xE0/0x01/0x01) DEVICE class.

A minimal HCI transport: it carries HCI commands (EP0 class control OUT), HCI events (interrupt IN) and ACL data (bulk OUT/IN) between the USB host and a controller the application implements. No HCI logic lives here - the class never inspects a command or synthesizes an event. Mirrors the Python library's usbip/classes/device/bluetooth.py.

Bluetooth USB Transport Layer (Core spec Vol 4 Part B):

• device class 0xE0 / subclass 0x01 (RF) / protocol 0x01 (Bluetooth)
• interface 0: interrupt-IN (events) + bulk-OUT (ACL out) + bulk-IN (ACL in)
• interface 1: SCO isochronous (6 alt settings) - descriptor-only / no-op
