Resolves #338
Description
Updates the algorithm used to read the HID descriptor from HID devices. Empirical testing indicates that some devices do not support reading the HID descriptor via the class-specific Get_Report() method described in USB HID 1.11. This changes the HID read to read the entire configuration descriptor and parse the HID descriptor out of the larger structure, and gives compatibility with a broader range of devices.
Supports a broader range of devices.
How This Was Tested
Verified against emulated USB devices in QEMU.
