fix: use class matching and double-pointer refs

Browse Source 
IOServiceMatching on idVendor/idProduct numbers is unreliable (single-key
matches fail), so match the IOUSBDevice class and filter VID/PID in user
space via the idVendor/idProduct properties.

QI'd interfaces are double-pointer references: *ref is the interface
struct and methods are called as (*ref)->Method(ref, ...). The old code
treated the slot as the struct and crashed on the first method call.

Verified on a physical dongle (PID 0x02E6): probe opens the device,
enumerates EP 0x04 IN/OUT and EP 0x05 IN, and register reads via
DeviceRequest return valid values (MT7612 ASIC version).
