Description:
I have bought ROCCAT Kova mouse several weeks ago. When I plug-in it into usb port, it begins to respond after 11 seconds. Then it's working properly. This is what happens (dmesg log):

usb 6-1: new full speed USB device using uhci_hcd and address 3
# here it hangs for about 11 seconds and mouse doesn't work and after that:
drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed

Maybe this is not big deal, but the whole boot process is longer by about 10 seconds. I figured out that /sbin/udevadm settle (rc.sysinit) is waiting every time for this mouse to be initialized. Plug in/out during boot isn't really convenient so I found workaround: added parameter --timeout=1 to /sbin/udevadm settle. But I'm not sure if it is safe?
