this driver is supposed to be in the SP1, I have this
installed on my computer and I get an error message when I
try to install and connect my new digital camera- the
computer finds the new hardware and goes to install it and
comes up with a message suggesting that the usbccgp.sys is
missing although I found it in the service pack files-
this is quite frustrating. If you run across any
information, during your quest for answers, that may help
me out could you forward them to me please. EREK
