USB host is not detected

I know is a problem that I have on BeagleCore, not BeagleBone, but since the boards are kind of similar, I would be very thankful to anyone who can help me.

I’m using a Debian Wheezy 7.11 image (https://beagleboard.org/latest-images) with Kernel 3.13.11-bone12.
The problem is the board is not detecting an Wifi module connected on the USB host.

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

It’s ok to be 2 of this with only one usb connection to PC ?

I checked the file that gives me the mode:

cat /sys/devices/ocp.3/47400000.usb/47401c00.usb/musb-hdrc.1.auto/mode

a_idle

My assumption is that here I should see a_host.
Is any way I could change the USB mode or is anything else that causes my problem?
