USB Bluetooth Dongle no es reconocido por BeagleBone Black

I'm attempting to figure out how to get a USB Bluetooth dongle to work with my BeagleBone Black. I've tried a few different ones to no avail, but have seen posts from others who seem to have had some success.

I have tried the procedure documented here: http://www.michaelhleonard.com/enable-bluetooth-on-beaglebone-black/

However, when I plug the dongle in, it doesn't even light up. Nor does it show up when I "lsusb". The BBB is being powered by a 2.5A 5V adapter, so power should not be an issue. Has anyone been able to get a USB Bluetooth Dongle working on a BeagleBone Black, and if so, which one was it, and what can I do to get it to at least power up?

What is the output in /var/log/syslog (or output from journalctl) as you plug in the USB dongle? This may give some clues as to whether the appropriate kernel module is available. -

Your link didnt open (possibly banned in my country). Try this link: hipstercircuits.com/serial-over-usb-on-beaglebone -

Same here - even though the Bluetooth service is running, the USB dongle neither lights up, nor outputs anything to /var/log/syslog -

Seems to be an issue with BeagleBone Black, I'm not sure. I was able to get it working on a Raspberry Pi. -

I've had a similar problem, and I think it's the usb hotplugging issue mentioned above. I stumbled into an easy workaround that works for me (running Linux 3.8). Try typing:

lsusb -v

The -v is important. If I leave it off, my device remains invisible and isn't powered on. When the -v option is present, it powers up and stays up.

In case you are running a 3.8 kernel: usb hotplugging seems to have issues. no. 1 recommendation is booting the BBB with the usb device plugged in already until hotplugging is fixed.

the power adapter should be sufficient with 2.5 amps.

Have you gotten it to work? I notice that even rebooting under both ArchLinux and Ubuntu doesn't work (Kernel 3.8.13-bone26). - Brent Fausto

I started a crowdfunding project to fix USB Hostplugging on Angstrom.

Have tested with USB Mouse, Keyboard, Serial adapter and hub. First I boot the system, with the USB host empty, then I plug in the above units, without problems.

They are all detected.

While I found that there are multiple issues with my BeagleBone Black (A5C) USB host, what helped me to get past the non-detection on USB is a 1000uF 16V capacitor across the +5V and GND lines of the USB connection. I removed a bit of the insulation of a short USB extension cable and soldered the capacitor to the red and black wires.

This might be a solution only for a single A5C board, but maybe it helps on other boards as well.
