Use the distribution, sample count and dropouts together; a single peak is not the result.
IP-MSE-01 / MOVE / 5 BUTTONS / WHEEL
Five-Button Mouse Test
Check left, middle, right, back and forward button down/up states and counts.
One mouse button is missing, stuck or mapped unexpectedly.
This focused entry uses the shared Mouse protocol. The measurement logic and Evidence version remain identical to the complete lab.
Remove the easiest false alarms first.
01
Use a desktop browser, keep the tab visible and close high-load tabs.
02
Move continuously on a stable surface; do not compare a slow trace with a fast trace.
03
Keep the same browser, Pointer API and connection path for repeat comparisons.
Run one repeatable protocol.
- 01
Press and release each supported button once.
- 02
Keep the pointer inside the test surface.
- 03
Compare hold state and counts for missing releases.
Evidence the result should expose.
DIRECT / INFERREDFive button states
DIRECT / INFERREDPress counts
DIRECT / INFERREDHold state
Separate observed, review and inconclusive.
Repeat under the same motion and load, then compare wired, direct USB and wireless paths one variable at a time.
Browser event rate, click response and pointer capture cannot isolate USB report rate or device-only latency.
Start with the likely path, then retest.
