Any way to connect Edison blocks to a microphone?

Hi -

When I run the Edison on the Sparkfun battery block and plug a USB microphone into the OTG port I don't see it on device:
lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Is this a power issue (it needs more than the 3.7v that the battery provides) or is it a different type of configuration issue (the mini-breakout board from Intel has a switch for power vs. USB port)?

Thanks for any help.

The fix appears to be in the cable - if I use an OTG USB cable to attach a headset I can get audio. On the Intel Arduino breakout there is a switch - but on the base block the OTG cable does the trick:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

The instructions at http://alextgalileo.altervista.org/blog ... io-edison/ were invaluable.
