The only way to go without rebuilding a kernel is probably to disable
uhid at the boot prompt on every reboot...

But you don't have to be a specialist to build a kernel. The needed
steps are documented on the Kernel FAQ page; you can follow them almost
blindly once you managed to get the sources and appropriately replace
<ARCH> and <MYCONF>:

The patch I'm running my system without disabling uhid is found
here (there are other patches floating around but this is probably
the simplest that does the job):
