USB is not detected

Hello,

I'm working with SoCrates board, and I'm trying to use USB mouse. Now I have my LED mouse blinking. But lsusb doesn't detect any hardware, except for root hub. This is also happening with my USB drive and with my USB HUB. All of them get power, but non of them actually works (USB is not detected, neither mouse, and HUB even doesn't give any power to devices plugged in it (when i plug mouse LED just blink for a moment). Do I have to include som drivers for this? I have included CONFIG_USB_MASS_STORAGE=y, so it should be able to detect USB flash? Also I've included Synaptics_USB driver, but I have message in dmesgs:Error: Driver 'synaptics_usb' is already registered, aborting...

Does anyone have any idea what should I do? And do I need drivers even for a HUB?

Thank you in advance,

Bojan

P.S. I'm using kernel 3.12

    I was using wrong end of cable to plug in mouse :)

    Flash and mouse now works fine, but I'm having problems with HUB. Do I need some drivers for HUB?

    i think you need a driver to allocation multiple end point.
