Emlid-raspberrypi1-raspbian-rt-2015feb.img.xz on MEGA

Hello team,
I flashed this image to a SD card on a rpi revB but observed that the USB connected kbd and mouse are disabled.
I can ssh into the pi just fine, but would like to use the usb kbd and mouse.
What am I missing?

Here is a gist of my problem and solution.
The messages I was getting on bootup were something like
Aug 12 06:25:25 raspberrypi kernel: [53474.195932] usb 1-1.2: new low-speed USB device number 105 using dwc_otg
So I replaced dwc_otg.speed=0 in /boot/cmdline.txt. This will effectively set the speed for USB2.0 devices (which my no-name KBD and mouse are).
I also explicitly added the following parameters (although the values are the defaults)
dwc_otg.lpm_enable=0 dwc_otg.fiq_fix_enable=1 dwc_otg.nak_holdoff_enable=1

I referred to the following links for the solution:
