You *really* should change the VID to one assigned to your company by
usb.org (you need to apply for one). The VID used in PB is assigned to
Microsoft and not yours to use. Once you got a valid VID assigned to
you, you can choose whatever PID you like for your devices, becuase you
own the "PID space" under your VID.
With MSD, changing VID/PID will not complicate the connection or
introduce any aditional steps -it will mount just as quiet as any other
MSD would (because it's really the interface descriptor class and
sublclass that are used to find the right driver and that remains the
same regardless of what PID and VID is used).

When I connect my device to a PC I would like it to appear as a "ordinary"

Client Mass Storage.)
Is it required that my company must have it's own USB VID/PID with
co-existing .inf-file on the PC, or is there some available ID's for common
usage for "ordinary" Mass Storage device that don't require any additions on
the PC side (no install of drivers)?
(Sorry if my question sounds stupid, but that is due to lack of knowledge in
this area.)
