11.1 Serial Number Suppression

11.1.1

Why is it required?

When programming the serial number to the hub, driver loading may take time for
unique serial numbers. If serial number suppression is enabled, it forces the USB
driver stack to ignore the serial number of the device. Therefore driver loading will
not take long time to load the driver for the device.
11.1.2

When is it needed?

In CLI application, suppression is required for the following arguments
1. "/cv" or "cvl"– if compare and verify option is present
2. "/pser" - if programming serial number option is present.
11.1.3
