USB: serial: cp210x: add Silicon Labs IDs for Windows Update
Quoted 5 lines · Karoly Pados
Silicon Labs defines alternative VID/PID pairs for some chips that when used will automatically install drivers for Windows users without manual intervention. Unfortunately, these IDs are not recognized by the Linux module, so using these IDs improves user experience on one platform but degrades it on Linux. This patch addresses this problem.
How does this work; do these chips now come with the "windows update" PIDs, and the silabs drivers then reprogram them to use other PIDs once installed?
Is this documented somewhere?

This kind of revision information should go below the cut-off line (---) below. I'll just remove it this time unless there's a resend.

I may shorten this somewhat.
