The way this works is that the chips still come with the standard SiLabs IDs. 
When the chip is integrated into an end-user product, the product manufacturer 
has the choice to reprogram the IDs. If they are left on the factory standard 
setting, the user will have to install drivers manually (go to SiLabs website, 
search, download, install by hand). Alternatively, the product manufacturer can 
reprogram the IDs to the "new" ones for Windows Update before shipping it to 
the customer, in which case Windows will automatically find, download, and 
install the drivers when plugged in the first time.

About the cutoff line: Sorry about that, now I know (first kernel patch for 
me). It seems you prefer to just adjust the commit message for now, otherwise 
let me know if you'd like me to resubmit.

Best,
Karoly
