I encounter a problem...when the USB Key plug in ,USBProber shows "Interface #0 - Mass storage/SCSI" at USB Key's configuration descriptor item. Is there any way to modified to "Interface #0 - unknown" or "Interface #0 -Chip/Smart-Card" in USBProber?? Is it working normally just after modify the descriptor ??? How to modify the descriptor via IOKit.framework or other.. I just wanna make computer to treat the USBKEY as vendor specific device,and the interface is unknow.
