As I said, test_fusb isn't anywhere on my hard disk (or find was lying
to me).  Anyways, I ran test_usrp_standard_tx and got the following:
TX d'board A: <none>
TX d'board B: <none>
xfered 5.37e+08 bytes in 16.8 seconds.  3.2e+07 bytes/sec.  cpu time =
5 underruns

I'm assuming this means the firmware was uploaded properly..  LED0's
blinking rate slowed to about 1 Hz, as expected.  However, LED1 doesn't
seem to work.  "usrper led1 on" doesn't do anything.  "usrper led0 on",
however, makes LED0 turn back on sooner than it should, and it then
resumes blinking at 1 Hz.  led0 off does the opposite.
"./usrper 9862a_read 1" also works as expected.

Is there something additional I need to do to get LED1 working?

Actually, my goal is to have a sandwich named after me.
