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?

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
