• Manufacturer Part Number: pl-2506b
• Description: Pl-2506b Hi-speed Usb To Ide Bridge Controller
• Manufacturer: Prolific Technology Inc.

The last entry of this table must have a bLength of 0 to indicate the end of this table. If the host tries to
access to the string descriptor beyond the last one, a zero-length data will be returned. The following
table shows one example of valid EEPROM contents:
The user could also define other strings, 4 to 6, to hold useful information for the drivers and/or
applications, such as software authorization codes, symbolic names, just to name a few. However, the
total length of this table must not exceed 256 bytes, the supported maximum size of the external
EEPROM.
