USB-202 is a USB 2.0 Full Speed(12Mbps) and Low Speed(1.5Mbps) compliant USB hub which isolates between a USB host and four downstream ports with 600VDC. Each of the four downstream ports are also isolated independently. With USB-202, it can be expected to eliminate ground loops that can cause measurement errors and equipment from surges, common-mode voltage, static discharge, magnetic fields, and radio frequency interference.There is no need to install any drivers. It works with every operating system such as Windows, Linux, Mac OS X.
