Jerry,
It's been a long time. We have had this working on MAC's for months now.
We have not had any reason to release the HOST code because we have not
had any updated firmware. The problem we are running into is that my
Windows programmer is telling me we need a device driver to access
Vendor Requests to EP0.
Do you know if this is true? Somebody said LibUSB from Microsoft would
work but both programmers said they could not get anything out of it.
These are full speed devices.
How about IOS and Android would this work with them as well?
Thanks,
Gordon

Hello Gordon
Is there a way to send messages over endpoint 0 from OSX?
Your audio DAC is USB2 high-speed right?
If your firmware is set up then you _should_ be able send up to 64 bytes at a
time with a VENDOR_REQUEST packet to EP0.
If you use libusb then something along these lines. I'll leave the
anti-bricking strategy up to you :)
libusb_control_transfer(handle,
LIBUSB_ENDPOINT_OUT | LIBUSB_REQUEST_TYPE_VENDOR |
LIBUSB_RECIPIENT_ENDPOINT,
SET_LED, // request ID
BLUE_LED, // wValue
0, // wIndex - ignored here.
data, // uint8_t* data
bytes, // # bytes
timeout);
HTH.
Jerry.
