3m usb touchscreen controller question?
a little info first..
at first had the 3m touchscreen (serial version) but it seen that the gps works better on serial then usb(more software option other than just delorme). now i only have 2 usb input and 1 serial so in order to use my gps in a serial i have to change the 3m touchscreen from serial to usb... so i just got my controller from touchwindows.com yesterday and today is sunday(meaning they are not working today) so my question is do the controller (usb version) need any other power connection other than just connecting the usb in... because my seriual version did need powering(9volts 500ma)... now can anyone help mw"do i need external power for the usb controller?
i'm 3 seconds away from connectin some power into it.... :confused:
