Cisco has a usb driver for the 7921 phones but do they have one for vista 64? Trying to configure a wireless phone and need to do the work on a vista 64 bit machine.
I don't think there is, with a support contract you can browse the download area yourself.
I don't believe there is a driver for vista yet (32 or 64 bit). I looked in the downloads section and the newest version of the usb driver installation says it only supports 2000 and XP. You can find the readme here: http://www.cisco.com/web/software/282074239/24333/USB-Install-7921-7925.1-0-2a-Readme.pdf
