Reply to Trigger Finger not recognized by windows vista

hey folks... ive dug out a trigger finger and am trying set it up on a 64 bit SP2 asus VISTA computer.. ive installed the 5.0.3 driver for usb from m-audio.. but when i plug it in it gives me the "usb device not recognized" msg. Ive uninstalled the drivers and reinstalled ..etc to no avail...

the trigger finger DOES work on my XP tower ( not an option for gigs)

and oddly enuff.. my axiom25 IS recognized and I've been mapping it with pretty good results.

would like to use the trigger fingers for its faders


any ideas would be welcome!!!
