So what can be the problem my device not being found. lsusb is working and is detecting usb port connected to usrp.
Thanks

 Hello!

That looks right so far. Does running 

lsusb

before and after you connect the USRP show a difference?
You're looking for a device with the vendor/product ID 04B4:8613 or FFFE:0002.

Did you build that UHD yourself or did you install it as a binary?

Best regards,
Marcus

Hi all,I have tried connecting my USRP to my laptop via USB cable. But anything is not being detected even though i type in sudo "uhd_find_devices". It says 
linux; GNU C++ version 4.8.4; Boost_105500; UHD_003.009.git-144-g407e3086
No UHD Devices Found
 I have also used this command below. But I have not seenany difference. Is there a problem with anything. I am using USRP1. Should I rewrite any udev rules? or is the UHD installation is not latest or not properly done?  Please reply ASAP. 
Thank you very much.cd usr/lib/uhd/utils
sudo cp uhd-usrp.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger
