32 * NOTE: It is common practice that MTP devices use some dummy
33 * descriptor cludges to be automatically detected by the host
34 * operating system. These descriptors are documented in the LibMTP
35 * library at sourceforge.net. The alternative is to supply the host
36 * operating system the VID and PID of your device.
