Sembra che bisogna aggiornare il firmware.

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
