Sounds like your USB died. Have you tried using a different USB-port on
your computer to find out if it is a problem with the BBB or with the
host-PC?

If you look at the diagrams in the System Reference Manual, the BBB uses
100K Ohm pull up and pull down resistors to tell the processor how to
boot. So any load low enough to cause a line with 100K Ohm pull up or
pull down to change logic state

I had trouble (viz. gave up) working with input pins with the device tree.
I ended up doing all the init at run time (once I'd made sure nothing else
was using the same pins in the device tree).
Check that you have removed any reference to the HDMI in your

1GB ram would be awesome on the BBB.
So whats this green initiative ? Because an X15 with 4GB ram would be

Hi Frederic:
You could make the 74HC541 work, since it has a CMOS input and should not
load the BBB during boot, provided that it has power supplied the entire
time the BBB is booting.
I was thinking more of something like the 74CBTLV3126 bus switch which
would disconnect your existing circuits

.
As far as I can tell this is identical in all respects to the TP-Link
TL-WN727N in the list of supported
Most adapters work. If you are just trying to connect to a network you
don't have to be picky. If you are using your BBB for hacking like I am,
then you might want something like the Alfa AWUS036H.
