I have a similar question, and that's how to get anything recognised on the usb port on the Break out Board (BoB)
No USB devices are recognised on the BoB, but the same Edison SOC in an Arduino board with the USB switched to host port will successfully show the devices, and I can use them.
dmesg on the Arduino board shows "pmic_ccsm pmic_ccsm: USB ID Detected. Notifying OTG driver", plus a load of other messages about found devices, but there's nothing on the BoB about any devices, nothing at all.
'lsusb' shows devices on the arduino, but I get error -99 on the BoB.
Maybe the host/client line is pulled low or high in hardware, preventing the USB from functioning as a host? Or is there a pin I need to pull high/low to force it into host mode?
Also, I've tried using both LiPo power and external 12v Power (on J21). System boots fine with both methods, but no host USB on the BoB.
just to clarify I have Arduino board only....
David, please confirm, as it seems odd that you and I have different results for Arduino...
I have usb working via a cheap usbOTG adapter purchased here (http://www.dx.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774)
dmesg output when usb audio device & OTG (micro usb -> fullsize) was attached:
Prerequisites as per manual: USB host mode always requires use of an external power adapter.
so first find a power supply then move switch from usb mini to usb A
then lsusb and dmesg provide output...
But now how to use camera?? as per original query...
Firstly Dan, thanks, that's solved my problem. I was using what looked 'like' an OTG adapter, but actually wasn't. I changed it for a proper one, and it worked. Yay!
Secondly, Peepo.com, My USB works when I switch the microswitch towards the larger USB port. That microswitch enables the micro-usb port or the full-size port (not sure of the proper names, sorry), but they can't operate both at the same time, hence the switch.
Above picture is very helpful! I just complained elsewhere that there's no picture in the breakout board docs about where or how to actually hook up an external power supply.
mini breakout board tip: J21 is the header for external power connection. The pin closest to the edge of the board is ground (it is the one with the square solder pad on the bottom/back side of the board).
Hardware for Familiar's audio/video I/O (sound card and web cam) connected, powered, and recognized. Black box to right is a hub, to the left is a 9V battery. I'll have to see if I can power all this and WiFi too from that 9V battery, but so far, so good. Amp for speakers to be powered off a separate battery...
but what did you do with your camera?
and which camera board is it?
Thanks for the mini-breakout board tip. I tried connecting a freshly charged LiIon battery (specifically this one from Sparkfun: Polymer Lithium Ion Battery - 2000mAh) to J21 but I can't get it to start (it boots up fine if going through USB).
The breakout board doc mentions a boot voltage selection mechanism but I'm not seeing any obvious way to make it switch over. What am I missing?
Might not have enough voltage? I had it working fine today with a 6.6v Life Battery
"Intel® Edison is a low-power device. In general, it does not draw more than 200 mA with 600 mA short duration
spikes during Wi-Fi transmit. Therefore, an Intel® Edison device may run on USB power (when configured as a
device), or an external power adapter from 7 to 15 V."
raminf you can attach your single cell lipo battery(don't try to use anything but a single cell lipo) to the J2 header on the mini-breakout board (the pin with the square shaped solder pad on the bottom/underside of the board is ground). If your curious, you can see the schematic here MINI_EDISON_BREAKOUT_HVM_8_26.pdf, the J2 connector is on page 3.
Edit: Square pin on J2 is not GND it connects to the positive + terminal/lead of the battery.
also, schematics are available here: Intel® Edison Breakout Board Schematic (pdf)
