EEPROM format and contents
Table 7.
The remaining space is available for the string blocks indexed at locations 8, 9 and 10.
Strings
The strings referred to above (locations 8-10), are the USB string descriptors referenced
from the device, configuration and interface descriptors. The value should be set to ’0’ if the
string is not implemented or to the offset in bytes of the start of the string block in the
EEPROM.
The first byte of each string block is the number of the characters in the string. Subsequent
bytes are the actual string, which need not include a terminating null (
