[USRP-users] Problem burning image to SD card for E312

Running Ubuntu 16 on my host computer...
I downloaded the image from:
Then I decompressed the xz file using xzdec:
xzdec sdimage-gnuradio-dev.direct.xz >> sdimage-gnuradio-dev.direct
And burned the sd image using the dd command:
sudo dd if=sdimage-gnuradio-dev.direct of=/dev/sdb1 bs=1M
The dd command apparently finishes without error after about 10 minutes, and I can see flashing lights on the SD card USB adapter, so I'm pretty sure it is getting written to the correct place.
But the card does not work in the E312. When I turn it on, the 4 LEDs next to the Tx/Rx ports light up, but there is no activity on the console window. I have another SD card that boots up fine, so I know the E312 is fine. There is clearly something wrong with the SD card. When I plug the old working card into my Ubuntu host machine, I can actually see the files on the card. When I plug the newly burned card back into the Ubuntu machine, I see nothing.
Any idea what I am doing wrong?
