Hello,

I'm having this error output on my built-in webcam Ricoh VCC7:

===>Device Descriptor<===
bLength: 0x12
bDescriptorType: 0x01
bcdUSB: 0x0200
bDeviceClass: 0xEF
*!*ERROR: Multi-interface Function code 239 used for device with no IAD
descriptors
bDeviceSubClass: 0x02
*!*ERROR: bDeviceSubClass of 2 is invalid
bDeviceProtocol: 0x01
bMaxPacketSize0: 0x40 = (64) Bytes
idVendor: 0x05CA = Ricoh Company Ltd.
idProduct: 0x183A
bcdDevice: 0x0100
iManufacturer: 0x00
iProduct: 0x00
iSerialNumber: 0x00
bNumConfigurations: 0x01

How could I debug more or find the cause ?

Thanks a lot,
Francois
