Ok, now that I got that usb box to work I can connect to Workbench HD. Next problem: The usb-box does not seem to power the JTV, mags are working, variax part isn't. Seems like I have to use the battery that is currently not loaded. Hmm, maybe it's just me but having to use the usb box instead of my POD HD 500 brings nothing but problems to my "dream rig". Have to wait some hours until the battery is loaded to test the new stuff.
