Digitized touchscreen issue

[jjensen201]

I am trying to run virtual box on a Panasonic Toughbook H2 tablet pc and am running into an issue with the digitized pen part of the screen. The pen taps don't register consistently in the virtual machine. You have to tap multiple times in order for it to register the tap. It seems that virtual box looks at the digitized portion of the screen as a usb device instead of being part of the screen. When I tell it to attach the digitizer as a usb device to the virtual machine, it then registers the taps properly and works great. The only problem is that the digitizer will no longer work with the host machine and is locked to the virtual machine. You have to attach a keyboard or mouse to be able to bring up the menu to detach the digitizer. I have figured out how to attach and detach a usb device via command line using the uuid for the digitizer. The tablet has programmable buttons that I assign to batch files set to enter the attach and detach commands. The issue I am running into now is that the uuid for the digitizer keeps changing. It works when I first start up the toughbook and enter in the uuid to the batch files and will continue to work until it is restarted. The uuid is different after the restart and the batch files won't work until I get the new uuid and edit the files with the new uuid. Is there any way to attach and detach a usb device through the command line with a static uuid? Is there another command I can use to accomplish the same thing. The command I am currentyl using is "C:\Program Files\Oracle\VirtualBox\VboxManage controlvm "Windows 7" usbattach/detach uuid." I have to have this setup as we have a proprietary software that can only run one instance in Windows at a time. The software has two separate pieces that cannot run at the same time. You choose which piece you want when you first launch the software. You can't change on the fly and have to close and reopen the program to switch areas. Most of our users have desktops and only use one piece at a time depending on their job title. They don't need to switch back and forth. I have one particular user who is a field worker using this toughbook and needs to be able to run both pieces at the same time in order to effectively do his work. He would otherwise have to continually close and re-open the program several times a day which slows him down too much. Thanks for your help.
