Everywhere a frequency is expected you can use a float followed immediately by an SI suffix.

Try another cable and ensure that the cable is properly seated on both ends. If you're using an external USB hub, perhaps in a monitor, please try without the hub in the path. > The bitstream it was trying to load was: > > /usr/local/share/usrp/rev4/std_2rxhb_2tx.rbf That's correct > I know that there is at least some communication going on with the > board, because when I power it up I get the green LED blinking at a > little over 3Hz.

When power is first applied, it should blink at about 3 Hz. After any application is run (which loads the "real firmware"), the LED should blink at approximately 1 Hz.
