Re: USB class

Tech-Archive recommends: Fix windows errors by optimizing your registry

you shouldn't do it, stuff like this is internally being cleaned out slowly.
use your own class.

For a long time, Microsoft has been mentioning in this group (and various
places in the documentation) that peripherals are required not use
Class=USB in their infs because that's reserved for host controllers and
hubs. Dire WHQL consequences have been hinted at.

I was just trying to convince one of our firmware guys of this, and he
pointed out that there are several .inf files in Windows\INF that violate
this rule, including many that are WHQL signed... notably many things that
act like thumb drives such as media players, as well as a couple of modems
(mostly this question comes up around here with respect to development
devices such as FTDI/EZ-USB/etc.).

So... What's the current state of this advise? What's the actual fallout
if you violate this rule?
