Different volume on ´my two controllers

Hi! I'm trying to install two XP-10 om a Win XP computer and I get different volumes for the two devices. Same setup all over.. I also have a problem to get the controllers to controll anything in XP. Any ideas??

You will have to adjust the volumes in Window's properties for each device (right-click the speaker icon on taskbar, then select device and adjust volume.
The problem you have may be due to a bug in the latest MIDI driver. The midi agent instead of device ID shows (hid#vid) and sees only one controller when two are connected. I am having the same problem right now and I'm desperately lookin for a solution - the older drivers..
