Hello there,
I made a USB-Audio Interface that works fine.
So I added and HID-device (in and out endpoint) to be able to "update"
the firmware - fine, too.
Now I added the descriptors for a standard midi device - so everything
works fine, BUT the AudioDevice (the 'real' audio device and not the
MIDI-device named "usb audio device") causes an error in the device
manager!
Midi works fine...has anyone an idea what happenend ?
Does Win XP support usb-midi and usb-audio at same time ? Perhaps it is
a windows bug ?
But under Mac OS-X no error occours, but the device is not playing audio
at all :-(
Can anybody send me a complete usb-descriptor of an device that has
standard audio and midi ?!?
Thanx for any help
Daniel
