I have not found that to be a viable position given the amount of stiction on Huge even after all the mods. I get the feeling that Huge was design to be operated with the index fingertip, with the palm lying flat and thumb positioned at the center of that cluster.

You can see from my picture the thumb button + wheel cluster on Huge is pretty far back in relation to the hump, compared to Ploopy. This also causes my wrist to be elevated unnecessarily on a setup with proper ergonomics for every other peripheral. Height of wedge + thickness of original wrist rest makes the entire unit quite tall. Huge is very flat and was painful for me to use without a wedge.

Patch originally implemented against ubuntu 16.10 kernel 3.19.0-82 sources. If the module is already compiled for the current kernel it skips the unnecessary steps so it doesn't really slow things down unnecessarily. You might even want to run it in some startup script on bootup.

Please note that the mouse might not work very well until you run it (axis swapped, buttons not working etc) because the default usbmouse driver is a rather naive implementation of the protocol. After kernel is updated, just run install.sh again.

You'll have to run update-grub once after first installation. My script updates /etc/default/grub to blacklist the specific usb-to-ps2 adapter from being associated with usbhid so usbmouse always gets control of it.

Both usbhid and usbmouse drivers thus compete over access to the mouse when both are loaded. Typically mouse devices use the usbhid driver, but I patched the simpler usbmouse driver for my purpose.

To compile & install the module for your current kernel, run the install.sh script attached to this gist. The module logs warning messages to syslog when the scroll state changes.Д¬omment out the line dev_warn(.) if you don't want it. I find this good enough to be usable/useful. (while not moving the mouse or having any buttons clicked), then scroll the wheel and finally click the fourthД«utton again to go back to normal mode. So instead of keeping the fourth button pressed while scrolling, you click it once Therefore, by clicking the fourth button we get two 'no buttons pressed' events, and the code then toggles However since 'no buttons pressed' is only ever reported when releasing a single button being pressed,Дetecting multiple 'no buttons pressed' events can be used to identify usage of the fourth button. It seems the fourth button generates events, but the state of the button is not represented in any bits (at least by said usb-to-ps2 adapter).

No idea how things work with other adapters. PS/2 keyboard + mouse controller' usb-to-ps2 adapter. When connected through a 'ID 04d9:1400 Holtek Semiconductor, Inc. This patch alters the usbmouse kernel driver to support a 'scroll wheel mode' using the fourth button (the red button) NOTE I now have a standalone driver available here which is easier to install: Logitech TrackMan Marble FX scroll wheel patch for the Linux kernel
