Why does my USB 3.0 device not work correctly on my E6640A, EXM Wireless Test Set? All my USB 2.0 devices work correctly.
Some USB 3.0 devices require a new instrument driver to be installed into your E6640A in order for the device to operate correctly. Install the USB 3.0 driver software for Windows® 7, 64-bit operating systems. The INTEL drivers are located here and it is advised that you search for "usb 3.0 driver" in the search field once on the webpage.
