Serial Number For Composite Device
Posted by abc.bhaskar@gmail.com on November 1st, 2007


Dear Team,

I am having USB Composite device ( HID + Mass Storage).

I am aware that if I implement the Serial Number in the device side,
Windows will not prompt for new driver when the device is connected in
the different USB port.

I verified the same with single interfaced device also. But even after
implementing Serial Number in the case of Composite Device, Windows is
launching New Hardware Found pop up.

Do I need to modify any other field in case of Composite Device so
that Windows recognizes the device in any USB port.

Regards.
