Description

Description

The Dual Shock 3 does either not vibrate at all or vibrate for 10 seconds. It happens for almost all cores. N64, PSX and Dreamcast, so I don't think it is a core-related issue.

Expected behavior

Vibrations of the duration of one second max.

Actual behavior

See description

Steps to reproduce the bug

Use a Dual Shock 3 in PSX

Research direction

No source file or test is named. Start by reproducing the issue with a Dual Shock 3 on Lakka in the PSX core, then compare the rumble behavior across the affected cores. Done means vibration is reliably triggered and never lasts longer than one second.
