Not sure if this is old/new news or applicable, but I know I am wanting native DSD for use with HQP / Lampi

http://www.amanero.com/drivers/nativeDSD.txt

To enable/disable native DSD on Combo384 an USB Control request must be sent to endpoint 0. This procedure is supported on all firmware versions.
On firmware_1099rc1 an USB alternate settings "2" with a native DSD endpoint is supported.

The control request is of type Vendor to the Device.

bmRequestType=0x40,
bRequest=0xB1,
wLength=sizeof( struct VAD_DATA ),
Data is a variable of type struct VAD_DATA

struct VAD_DATA {

unsigned int command;
unsigned int length;
unsigned int buffer[64];
};


To enable native DSD
command=0x8000
length=0
buffer=undefined values

To disable native DSD
command=0x10000
length=0
buffer=undefined values

Okay - I was wondering what you were on about in the first post :)

Yeah I kind of figured that after the fact, oops :) I know the Lampi crowd (me included) using HQP/NAA will be happy to hear this. I asked the admin to append "Linux" to the description.

Do you know a procedure on how to write the published commands in the firmware?
