Question

How can I obtain a certified version of the Silicon Labs VCP driver with the Ignore Serial Numbers enabled?

Answer

UPDATE: While the older Silicon Labs driver installer supported a setting to turn off serial enumeration, the new DPInst-based installer does not. However, the system registry may be manually updated to cause Windows to ignore serial numbers for any PID/VID/Interface desired. Please refer to the following Knowledge Base article for more information on the registry update procedure.
