Yes I know that there are other threads on this, but after reading through a gazillion I can't find an answer so I though I'd start another. I the a "device in use" error message. I've seen this: "Move the BlackberryUSB*.kext folders out of the /System/Library/Extensions folder, restart, then you can connect to your BlackBerry in Parallels with no problem." at http://www.alexking.org/blog/2006/08/07/tether-blackberry-modem-parallels/ ...but I don't have any BlackberryUSB*.kext files. Need help
