When it is up again, Windows searches for new devices on this USB port. If your board has a separate power supply, you could also unplug the USB cable, wait a second and replug it to have the same effect.<br /> When no USB cable is plugged in (well, also when it is plugged in), the DP+ line must be high, pulled up by a 1.5k resistor. If it is low, no USB host will scan the bus for new devices. You can easily check that with a DMM. </p> http://forums.leaflabs.com/topic.php?id=2643&page=2#post-22160 Tue, 29 Jan 2013 17:07:15 +0000 xchg.ca 22160@http://forums.leaflabs.com/ <p>I'm using Windows7, looks like I don't have ability to use SerialUSB it goes nowhere when I'm truing to print... hm<br /> May be my little schematic doesn't work properly?

What Operating System are you using? It may be that the Maples USB CDC serial is good enough to use the default driver; or you installed the driver ages ago? </p>
