Hello Ravi,
this is good:

so your PC's operating system detects it.

When you built UHD, did it say that USRP1 was enabled?
If you can't remember, go to where you've built uhd, e.g.
/home/vsrravi/uhd/host/build, and open the CMakeCache.txt.
Search for ENABLE_USRP1 ; you should find a line like
ENABLE_USRP1:BOOL=OFF

Best regards,
Marcus
