USRP installation problem

Hi,

I tried to install the newly purchased USRP. However, plug in USB cable
to
my computer does not generate message of “Found New Hardware” as
described
by http://gnuradio.utah.edu/trac/wiki/USRPWindowsDriverInstall. I am
sure
the power is on since the board is hot. Has someone meet with the same
problem? How you solve it?

Regards,
Nan

This might be a stupid question, but are you plugging in the power
source? You need to plug in the AC adapter AND the USB cable to your
machine. You will see a green light on the board light up.

Do other USB devices work in the same port you’re plugging the USRP in?

Does the green LED on the USRP illuminate?

With Matt’s help, I found out the reason. I use USRP with TVRX daughter
board. When plugging in TVRX board to USRP in RXA slot, I plug in with a
wrong direction (without enclosure, you can plug in TVRX with antenna
connector faces either left or right, but only one direction can work).
After I changed the direction, it begins to work properly.

I resolved this with Nan.

Just to be clear for everyone – when you plug in daughterboards,
follow these rules:

  • If the standoffs don’t line up, you have the boards installed
    incorrectly
  • TX daughterboards cannot go in RX slots and vice versa
  • Daughterboards on TX-A and RX-A should be installed right-side up
  • Daughterboards on TX-B and RX-B should be installed upside-down (i.e.
    rotated 180 degrees)
  • The side edge of the daughterboard should align with the side edge of
    the USRP PCB
  • The TVRX must be installed with the big F connector sticking off the
    edge of the USRP. If the USRP is in the enclosure this means that the
    TVRX will only fit in slot RX-B
  • Never power the board up if any of the above is violated. If you
    power it up and the led doesn’t blink, immediately power down and remove
    all daughterboards before trying again
