--- Comment #2 from Lovekesh Solanki (lovekeshsolanki00@gmail.com) ---
It is possible the commit e716edafedad causes mt_get_feature() to reject the
Win8 response due to firmware returning mismatched report Id. So
hid_report_raw_event() is never reached and device doesn't switch into
Precision mode.
Rather than reverting the commit, which would drop the ID check for every
device, it may be possible to add a quirk for 0b05:1a30 so only this model
tolerates the mismatch.

I have prepared a patch which does that, but I don't have the hardware so I
cannot confirm.
Would it be possible for someone to test it? I'm not sure how to send it here
I'm not familiar with the process.
