Tired of crawling under your desk to unplug and replug your USB devices when they crash? Got USB connected test equipment that is in a hard to reach location?
Then the USB Power Resetter is ideal for you. With the USB Power Resetter connected to a spare USB socket on your PC or USB Hub, you can turn the power off and on to your USB device.
You can use the windows API to reset the port, but while that will restart the plug and play routine, if your USB device has properly "hung" then sometimes the only way to fix it is to completely disconnect the 5V line - that's what our resetter does.
We use it here with a USB printer that goes to sleep, and requires the USB cable to be pulled and replaced to start up. We also use it with a datalogging device at a remote customer site. When the datalogger hangs, we can just restart it without any need for plug pulling!
The USB Power Resetter is controlled by our Command Line Tool for DOS/Windows or with a small addition of code to your own programs (Sending a string to a COM port). The USB Power Resetter has been tested in Windows and LINUX, and there are code examples provided to add code to Visual Basic .NET or C# programs on windows, and PYTHON on LINUX.
The USB Power Resetter has a high power MOSFET capable of switching 2 Amps. The supplied firmware has 3 built in operations : USB OFF, USB ON & USB RESET, The reset turns off the USB power, waits for 2 Seconds and turns the power back on.
