Just noticed this old thread as I was struggling to get my virtualized (VMware Fusion) Windows XP Pro to recognize Crown Xti amps via System Architect (2.0) or the recently released Band Manager apps.
After many hours of investigation I discovered that the Crown Xti looks to the OS like an HID (Human Interface Device)i.e. a keyboard or mouse. Typically HID are controlled by the host of the virtual OS and so are filtered from view or control by the virtual os. The fix is to edit the config file of VMware (.vmx) to show all USB connections in the settings tool bar and allow the the choice to connect to them via the virtual environment.
Here are the steps to do it:
Editing configuration file for VMware Fusion to allow HID (USB) devices to be connected by virtual machine.
This was specifically to allow System Architect and Band Manager (Crown HiQNet) connect to Crown amps via USB in the virtual operating system. In my case it is Windows XP Pro.
Be sure to exit the virtual host and close the VMware application before editing this file.
One must edit the VMX config file. Which is found by navigating the following path:
~/Library/Application Support/VMware Fusion/Virtual Machines/Boot Camp/%2Fdev%2Fdisk0/Boot Camp partition
Note that the path starts in your user directory and may or may not include the path elements that are Boot Camp specific depending whether or not you are using a Boot Camp partition.
Steps to edit VMX config file
Right click (control click) file: "Boot Camp partition"
Select "Show Package Contents"
Highlight "Boot Camp partition.vmx"
For safety I made a copy of this file which I saved to my desktop.
Right click (control click) and select "Open with"
Choose "Other" then browse to text edit application of choice
Use any text editor application. I used the Apple supplied TextEdit app.
I added this line:
usb.generic.allowHID = "TRUE"
I put this after the line:
usb.autoConnect.device0 = "path:4/0/1 autoclean:1"
Save file. Quit text editor.
When virtual machine is relaunched one will see all the USB connections in the Tool Bar and one is able to choose to connect to those USB devices in the virtual machine (specifically).
I hope this addresses your issue!
