Protocol
- Vendor request is used to reset the engine and flush the buffers
- Endpoint 2 is used for host-to-device command/parameters transfers
- Endpoint 6 is used for device-to-host status/data transfers
X denotes "any value" in the following description
Vendor requests
- bRequest=0xB3, wValue=X, wIndex=X, wLength=0x0A, data={ 0x0F, 0x03, 0x03, 0x03, X, X, X, X, X, X } - restart the engine (reset FPGA, reset FIFOs)
- bRequest=0xD0, wValue=X, wIndex=X, wLength=0x00 - disable communication (set FIFO reset), not used
- bRequest=0xD0, wValue=X, wIndex=X, wLength=0x00 - enable communication (clear FIFO reset), not used
