The Keterex USB-150 Full Speed USB Isolator provides up to 2000Vrms of galvanic isolation between a USB host and USB peripheral.  It is used in applications where a USB host and peripheral device operate at different ground potentials or where supply noise from the USB host needs to be eliminated.

The USB-150 Isolator is connected between the host and peripheral using standard USB A/B cables. An isolated 5V supply at up to 400mA is provided to the downstream device over the USB cable.  The Isolator is invisible to both the host and peripheral − no device driver or configuration is required.  Any full-speed USB device can be isolated using the USB-150 and standard USB cables.
