REV. 1.2.0
The USB interface of the V1410 is compliant with the USB 2.0 Full-Speed Specifications. The USB
configuration model presented by the V1410 to the device driver is compatible to the Abstract Control Model of
the USB Communication Device Class (CDC-ACM). The V1410 uses the following set of parameters:
Exar’s USB Vendor ID is 0x04E2. This is the default Vendor ID that is used for the V1410 unless a valid
EEPROM is present on the I
EEPROM will be used.
The default USB Product ID for the V1410 is 0x1410. If a valid EEPROM is present, the Product ID from the
EEPROM will be used.
The V1410 device can be used with either a standard CDC-ACM driver or a custom driver. When the CDC-
ACM driver is used, the driver has no knowledge of the V1410 device registers. Because of this, the V1410
device is initialized to the following settings:
