Description of device descriptor that the driver can handle.
Support descriptors can be used to match any form of class, subclass or protocol, or they can be used to match a vendor and/or product. If any field has the value 0, it is treated as a wildcard.
For example, if you want to watch for all the hubs, which have a device class of 0x09, you would pass this descriptor:
usb_support_descriptor hub_devs = { 9, 0, 0, 0, 0 };
See usb_module_info::register_driver() for more information on how to use this object.
