Usrp1 not responding


#1

Hi all-

I have a problem with my USRP. The device is not detected by the pc OS,
and the led’s do not flash or come on. I checked the power supply; I
can
find 6.33 V on the board when powered up, but not 3.3V. I checked the
voltage on the LT1085, and there is 0 V on the output pin.

Is it likely the LT1085 regulator has gone bad? Or could there be some
other explanation?

thanks!
eric
