Intellimouse features not implemented #3

Closed rasteri closed 6 months ago

jarpatus commented 6 months ago

@rasteri, I am trying to add Intellimouse support and am almost there, but have treoubles on last steps... I wonder if you are willing to help?

I have implemented PS/2 command buffer (https://github.com/rasteri/HIDman/commit/8878ecb2cc678cfe9939ebf54b1c5836244f85f6) so I can detect when driver enables intellimouse (https://github.com/rasteri/HIDman/commit/519cf02b84fe9c253e9f11d41fb087aa8307542f). Also implemented support for PS/2 resolution and scaling on commands, but those are not that important, can be tested e.g. with https://github.com/jarpatus/ps2set-dos/.

I have expanded PS/2 related code to support Z-axis and 4-byte reports. At the moment middle click works under DOS and Win98 and wheel scrolling does work if I fake it (e.g. map mouse Y-axis to wheel like I've done for debugging purposes).

However, I am unable to wrap my head around USB code, reports and stuff. I cannot figure out how I can make USB code to support scrolling. If you are willing to help, could you take a look of this commit on my fork:

https://github.com/rasteri/HIDman/commit/f6b9754f5e3a20176eb96b2270da4323d281251c

In ps2protocol.c I think I was able to do what it takes (case MAP_MOUSE_WHEEL), but in parsedescriptor.c my modifications do nothing (case REPORT_USAGE_WHEEL, do not mind swapped Y and wheel, for debugging only). Any hints?

Hacked together wheel support, it works with ctmouse and under Windows98! But it's a hack as I am parsing wheel input from bare data...

Hey I'll look at getting it integrated with the HID report stuff. It's a pretty complicated scheme.

jarpatus commented 6 months ago

@rasteri, I was able to make it work by adding wheel to standard mouse descriptor... not sure if you can do it like this, I still do not understand HID report descriptors and reports well enough...

Yeah the issue is that USB HID Boot Mode doesn't specify a mouse wheel. This will do as a workaround for now though. I'll do some testing with your fork

Thanks! FYI; I felt andventurous and added support for 5 button intellimouse, this is in it's separate branch intelli5b in my fork. Feel free to try it out if you wish. I had to modify standard mouse descriptor even more.

At least under Win9x IntelliPoint 3.0 software will now detect mouse as Intellimouse Explorer with 5 buttons and buttons really do work. I have no modern machines with PS/2 so I could try it out e.g. with Win11 or so...

That's great! I've tested and merged your 5 button code, and added an option to the menu to disable intellimouse if needed.

Also I've added options to enable HID report parsing for mice and keyboards in the menu. This is the "proper" way of enabling mice scroll wheels, but I leave it off by default because it's a "safe" option. Some USB devices have very strange reporting formats so best to leave them in boot mode as a default.

5-button code works flawlessly in Windows 10. I think we can call this one fixed.

Thanks again for your contribution!
