String Descriptors
Descriptors contain references to string descriptors that provide displayable information
describing a descriptor in human-readable form. The inclusion of string descriptors is
optional. If a device does not support string descriptors, all references to string descriptors
within device, configuration, and interface descriptors must be reset to zero.
The strings in a USB device may support multiple languages. When requesting a string
descriptor, the requester specifies the desired language using a sixteen bit language ID
(LANGID).
