What happens if you plug in a generic USB flash drive into one of the USB 3.0 ports? check that Do you know if the same applies for the B200?

Regarding Multiple USRPs to one machine For maximum throughput, one ethernet interface per USRP2 is recommended, although multiple devices may be connected via a gigabit ethernet switch. Check This Out Ron's suggestion will likely help you greatly and you'll find more threads in the fairly recent past on the same topic. -Ian On Jul 16, 2015, at 4:02 PM, Ron Economos Make sure the DC supply is plugged in.

Now, the authorities in my laboratory are using UHD compatible SD cards to run codes in USRP2. This is being done to prevent the application from crashing due to gnuradio bug #528.

Owner csete commented Apr 17, 2014 There has been an update to gr-osmosdr to properly select one channel (subdev=A:A) with gqrx. The thing is, I was able to run the benchmark_rx.py and benchmark_tx.py codes in another UHD upgraded daughterboard. USRP2 has been imaged > with UHD_003_002_001 image.
Thanks a lot for the help.
Looking through dmesg doesn't show anything >>>> > either. Contributor m0mik commented Apr 11, 2014 I assume that "subdev=A:A" is the one and only subdev that the B200 has so it shouldn't have the same issue as the B210. Is computation power w/ the number of interrupts an issue? That doesn't mean it shouldn't work, but I do not have experience with this controller.
Maybe your laptop's controller cannot provide sufficient power. Your help will be very very appreciated.Thanks, Nazmul-- Muhammad Nazmul IslamGraduate StudentElectrical & Computer EngineeringWireless Information & Networking Laboratory Rutgers, USA.
