Hi Master,
I've removed the duplication link for this bug. Its definitely a completely different bug.
After looking at the hidp kernel code, I found a recent mainline fix that is not yet available on our Precise kernels. This is upstream commit 4529eefad087f97 b33c0f31984d924 b1f15d7bae "HID: hidp: fallback to input session properly if hid is blacklisted".
I've cherry-picked this commit into the precise kernel, built a test kernel and uploaded it here:

Could you please give it a try and see if it fixes your oops? Thank you.
