Why do I not seem to have hidraw options on my system, and how can I fix my usb devices?

Question

Starting today, I noticed a few problems with my system. USB devices, including the internal ones such as microphones, don't seem to be working at all. I first noticed when my keyboard and mouse weren't responding - however, checking dmesg, both the logitech unifying receiver and my external mics usb connections were being recognized.

Thinking at first that the receiver may have simply stopped recognizing the input devices, I figured I'd resync them and I'd be good to go - except, that when I went to reference the needed hidraw device, I didn't have any. There is no /dev/hidraw, no /sys/class/hidraw, no anything it seems. (except a hidraw header under /usr/include and some hidraw files under /usr/src)

So that seems to be at least part of the problem - udev seems to be failing to do its job somewhere. But I've got no idea where to go next.

Here's relevant bits that might be useful:
From dmesg:

This same thing happened to me. I had to compile the kernel to get it to work. Before compiling the kernel you have to make sure you have raw HID enabled.

sudo make menuconfig

Device Drivers --->
  HID Support --->
    /dev/hidraw raw HID device support

If you don't know how to compile the kernel, you can do a quick google search. This is the one I used (Ubuntu): Howto compile Linux kernel 3.8 / 3.x in Ubuntu 13.04 12.10 12.04
