When detecting USB storage devices, we currently skip everything that is not marked as "undefined device class".
Composite devices such as tinyusb's CDC+MSC identify as "miscellaneous" (class 0xEF).
Introduce a new constant, USB_CLASS_MISC (0xEF), and allow the detection process to proceed for USB devices with this device class.
What does Linux do with such a device , is there a specific quirk or does it simply not check the bDeviceClass at all ?
