That is probably the case. Is it sound/usb/usbaudio.c you mean when you refer to the "standard USB audio driver"? So this will work with any device of class USB_CLASS_AUDIO (=1)? But the datasheet for the chip says Device Class 0x00: USB Revision 1.0 Device Class 0x00 (device defined interface level) Device Subclass 0x00 (not specified) Device Protocol 0x00 (not specified) Max Packet Size for Endpoint 0 8 byte Vendor ID 0x08BB Device ID 0x2702 Release 1.0 Anyway, I guess the easiest way to test is to bring my laptop into the shop and just try... //Petter ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
