can't connect to computer

hey there,

I just finished build up my PB+. I read the"getting startet guide" and install some software (USB Driver, Slic3r and pronterface). Then I connect the bot to my PC and... nothing O_O
Windows do not recognize any USB device. The green LED on the board is working - everything seems to be OK...

I have a Printrbor Plus and win7...

Sometimes the USB cable is bad, or the connection on the printer end is a little flaky.
When you plug the cable in and / or turn the Printrbot power on, your Windows computer should make a little ba-ding sound indicating a new USB device has been found. After a few seconds, you should be able to see it in Device Manager. See this post: www.printrbottalk.com/forum/viewtopic.p ... 55&p=24813

If multiple machines and USB cables have all declined to connect, you're narrowing it down to the Printrboard. Just as a last review, do you feel really good about all the power connectors (and other connectors for than matter,) on the Printrboard? Is the ATX jumper correctly in place (you mention getting the board green LED, but it doesn't hurt to check.)

You could also make sure you have good USB Serial drivers, you can download them at
