usbccgp.sys

Hi,
I read somewhere usbccgp.sys is the prefered parent driver than usbhub.sys
for a multifunction device. I use usbhub.sys for our usb device on windows
2000 and now want to move it to windows XP. I modified the inf for windows
2000, by simply changed all reference to usbhub to usbccgp. I then use this
inf file for the device installation on a Windows XP (we also used tested
our driver with the old usbhub with this XP machine), and delete some
related .inf file in windows\inf directory and the registry key in
HKLM\SYSTEM\CurrentControlSet\Enum\USB\ location. However after inserting
the device and suplied the new .inf file. Hardware Update Wizard in XP
reports that there was a problem installing this hardware, the name is
already in use as either a service name or a service display name. I suspect
this is because of the previous installation of this device with usbhub.sys
(the XP used with uncleaned registry entry).
Is my analysis correct? You guys have any comments?

Best Regards,

Wayut

I installed it on a fresh PC, but now the error message: "A service
installation section in this INF is invalid"

The fast way is to compare INF of other usb composite device for service
section.

That's the thing, I have a sample composite .inf file using usbhub.sys
but not with usbccgp.sys. usbccgp.sys file also is not available on
my PC, I had to download it somewhere.
I want to use usbccgp because I think it is a correct thing to do on XP,
although using usbhub is still okay.
Any of you have any sample .inf file using usbccgp? And where is
the official site to download this usbccgp?

Wayut

You don't download it. It's supplied with all the systems where it is
supposed to be used. On Windows 2000, you use usbhub.sys. On Windows XP,
you use usbccgp.sys.

You should not have to refer to the driver by name at all. If you have a
composite device, just don't put a line for it in your INF file. The
operating system will fall back to the proper driver based on the USB class
ID.

Yes, you're right, actually I remember I tried to do that, without defining
a driver for the
parent device and defined 9 (hub class) for the usb device class and 0 for
the subclass
in the device descriptor, but Windows still ask for the .inf file.
