[Bug 46999] New: Controller with invalid HID range value causes division by zero error
https://bugs.winehq.org/show_bug.cgi?id=46999 Bug ID: 46999 Summary: Controller with invalid HID range value causes division by zero error Product: Wine Version: 4.5 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: xinput Assignee: wine-bugs(a)winehq.org Reporter: gerbilsoft(a)gerbilsoft.com Distribution: --- I have an 8bitdo M30 controller, which is similar in design to a Sega Mega Drive 6-button gamepad. Attempting to play the game Sonic 3 AIR with the controller connected resulted in a division by zero error. I finally narrowed it down to a crash in xinput1_3/hid.c, scale_short(). It seems that, since the controller doesn't have analog sticks, it reports a range of 0. scale_short() doesn't expect this, so it ends up dividing by zero. Workaround: If range is 0, return 0. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
https://bugs.winehq.org/show_bug.cgi?id=46999 --- Comment #1 from David Korth <gerbilsoft(a)gerbilsoft.com> --- Note that the M30 has options to remap the D-Pad to Left Stick or Right Stick (default is D-Pad, aka "hat"). I'm not sure how that affects the HID ranges. If anyone can point me to a tool that can show the HID usage descriptors, I'll post them here. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
