6.0 USB Standard Descriptors
PL-2303HX supports one configuration with one interface and four endpoints. The descriptors are
basically stored in an internal Mask ROM. However, some fields could be optionally modified by
properly programmed external 2-wire serial EEPROM. The contents of all descriptors are shown in the
following sections.

Maximum packet size for endpoint zero is 64
Vender ID (1)
Product ID (1)
Device Release Number (1)
Manufacturer string descriptor index
Product name string descriptor index
Serial number string descriptor index (2)
One configuration.
Notes:
(1) – The Vender ID, Product ID, and Device Release Number could be replaced by the contents of external EEPROM.
(2) – The serial number string descriptor index could be defined by the contents of external EEPROM. If specified, the index will
be 3 instead of 0.

CONFIGURATION descriptor type
Total length of data returned for this
configuration.
One interface for this device.
Characteristic attributes (3)
Maximum power consumption (4)
Notes:
(3) – The Remote Wakeup attribute (bit 5) depends on the settings of the Remote Wakeup Enable (Setting in the Device
Configuration Registers, DCR, of PL-2303HX). If all remote wakeup sources are disabled, the bmAttributes will be 80h.
Otherwise, A0h is returned to indicate that this device is Remote Wakeup capable.
