Configuring Multiple Devices with USB

You can connect multiple devices in the following ways:

  • Multiple USB 2.0 or 3.0 interfaces—One device for each interface
  • Single USB 2.0 or 3.0 interface—Multiple devices connected to a USB 2.0 or 3.0 hub
Tip Sharing a single USB 2.0 or 3.0 controller interface on your host computer among multiple devices may reduce overall signal throughput. For maximum signal throughput, NI recommends that you connect no more than one device per USB interface.

To configure multiple devices connected to either separate USB 2.0 or 3.0 interfaces or to a USB hub, assign a different device ID to each USRP device. Because each USRP-2900/2901 device has the same default device ID, you must change the device ID for each USRP device before you connect an additional device to the host computer.
