Why does it do that? What if I want to receive the events regardless of
duplication(which I do)?

dmesg shows this:
OUTPUT[OUTPUT]
Field(0)
Usage(1)
Digitizers.0000
Logical Minimum(0)
Logical Maximum(255)
Report Size(8)
Report Count(5)
Report Offset(0)
Flags( Variable Absolute BufferedByte )
So Count = 5 and each values size = 8. {0x13,0x13,0x00,0x00,0x00}
> Also, if your device uses report IDs for the output/feature reports,
We're not using report IDs.
Thanks,
Jackson
