USB - Configuration Name Descriptor

Report Type: IN / OUT
Report Size: 32 Bytes
Acknowledged By: Command Acknowledgement

Report ID	Flags	Name
00000100	u 0000000	32 bytes

Report ID

HID Report ID. Always 0x04.

Flags

Bits	Direction	Meaning
u	OUT	Whether to update the descriptor; 1 to update it, 0 to leave it alone. For IN Reports this will always be 0.

Name

Unicode (UTF-16) representation of the configuration’s name. There is space for 16 characters in Little Endian notation (Least-Significant Byte first). Any unused characters should be set to 0x0000 and the string is considered terminated by the first occurrence of a 0x0000 character.

Notes

The name cannot be zero-length (ie. the first two bytes both 0x00), otherwise a Negative Command Acknowledgement will be returned in response.

The descriptor will not be stored into non-volatile storage until a Store Current Configuration command is issued, so any subsequent Get_String_Descriptor requests will continue to return the old descriptor, and any Set_Configuration requests or power cycles will lose the changes.
