I have a Samsung SCX-4100 multi-function laser printer working under OSX (well only the printing function that is). Only the scanning software is available for XP so I use Parallels to run XP on my MacBook. Using the latest Parallels beta 3170, I am unable to connect the SCX-4100 for XP to see. I keep on getting the message that the " USB device you are trying to connect to the virtual machine is being used by another application. Close that application or unplug the device and plug it again. Then try to connect the device again." This is weird because I don't have any programs accessing the printer at all. I really want to get scanning functionality working, any suggestions?
