If an application uses libmtp on the guest system,
it will complain with the warning message:
LIBMTP WARNING: VendorExtensionID:
ffffffff
LIBMTP WARNING: VendorExtensionDesc: (null)
LIBMTP WARNING: this typically means the device is PTP (i.e. a camera) but
not a MTP device at all. Trying to continue anyway.
This is because libmtp expects a MTP Vendor Extension ID of 0x00000006 and a
MTP Version of 0x0064. These numbers are taken from Microsoft's MTP Vendor
Extension Identification Message page and are what most physical devices
show.
