Hi list, I have been working with two N210s for a while now, and they have been working fine. However yesterday I started off again after a break, but one of the USRP N210 showed an error.

When I run the command 'uhd_find_devices' I get this output
-- UHD Device 0
Device Address:
    type: usrp2

Device serial no is not shown.

When I run the command 'uhd_usrp_probe' I get this output

linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.001.002-5239879

-- Opening a USRP2/N-Series device...
Error: RuntimeError: no control response

I am not able to figure out whats wrong. It appears to be a basic fault, that the device's IP address is shown, but still there is a control error. Will appreciate any help.
