[linux-audio-dev] Sending USB msgs to sound card through snd_usb_audio driver - how ?

Hi all. I am trying to control the settings of my EgoSys U2A sound card by sending it the same commands that I can see being sent to it when I am using the Windows U2A control panel. I naively thought that I could use libusb, but I cannot open interfaces on the sound card, because snd_usb_audio is using the device. Unloading snd_usb_audio releases the audio interface so I can claim it with libusb calls but that is hardly practical for changing settings occasionally. Are there any standard ioctl() calls in the snd_usb_audio driver that allows me to send messages to a USB interface, or any other way of doing this the civilized way - that is: through the driver ? Any pointers greatly appreciated. Cheers -- Jan Holst Jensen, Denmark __________________________________ Discover Yahoo! Find restaurants, movies, travel and more fun for the weekend.
