Whenever my mouse, a SteelSeries Xai, is plugged in, there is a 15 second delay until the mouse is properly recognized and starts working. This is specially troublesome at boot, where udev waits for 15 seconds doing nothing.
The following is the relevant information that I found on dmesg at boot:

As you can see, for 15 seconds, udev is doing nothing.
However, when I unplug it and then re-plug it, the process is a bit different:

Now it seems like it's recognizing parts of the mouse at 5 second intervals.
The problem might be with the mouse. I had problems with it in the past on Linux, so I won't discard it. However, I'm interested in at least a workaround so my boot process doesn't take so long (it's about 45s to the DE, so 15s of nothing is a lot). If whenever I plug it in I still have to wait 15 seconds, that's fine. The mouse works OK and doesn't reconnect by itself.
So: Is there a way to speed up the detection of a device, even if it's manually?
Or: Is there anything I can do to udev so it doesn't wait at boot for this particular device to respond?
