fix-ms-mouse-scroll

Patch to fix scroll wheel problems with certain Microsoft mice in Linux.

Problem exploration

Some wireless Microsoft mice have strange behaviour in Linux after working in Microsoft Windows - scroll is too fast. Possible workaround - reinsert mouse receiver to usb (i.e. power off receiver). More information can be found here:

• http://sourceforge.net/projects/resetmsmice/
• https://bbs.archlinux.org/viewtopic.php?id=177916

fix-ms-mouse-scroll patch for Linux kernel can fixes this behaviour.

Supported mice

Only Microsoft mice are supported, so device usb vendor id should be 0x045e. Usb devices with following device id supported:

• 0x07a5:
• Microsoft sculpt ergonomic mouse
• 0x0745 - Not sure, possible following mice:
• Microsoft Wireless Mouse 1000
• Microsoft Wireless Optical Desktop 3000
• Microsoft Wireless Mobile Mouse 3500
• Microsoft Wireless Mobile Mouse 4000
• Microsoft Comfort Mouse 4500
• Microsoft Wireless Mouse 5000

Supported Linux kernels

Patches tested on the following vanilla kernel and/or Gentoo default kernel:

1. 3.3.0 (tested only compilation)
2. 4.0.5 (tested compilation & really working)
3. 4.2.0 (tested only compilation)
4. 4.3.0-rc2 (tested only compilation)

Choose appropriate patch version

Following name convention is used: fix-ms-mouse-scroll-<v>.patch where <v> - primary kernel version for witch patch is developed.

• For kernel <3.3.0 try to use fix-ms-mouse-scroll-3.3.0.patch
• For kernel 3.3.0 use fix-ms-mouse-scroll-3.3.0.patch
• For kernel >3.3.0 but <4.0.5 try to use fix-ms-mouse-scroll-3.3.0.patch or fix-ms-mouse-scroll-4.0.5.patch (choose version with wich there is no error at kernel "build")
• For kernel >=4.0.5 but <=4.3.0 use fix-ms-mouse-scroll-4.0.5.patch
• For kernel >4.3.0 try to use fix-ms-mouse-scroll-4.0.5.patch and look at special notes about such case (or ask me to update patch if kernel build failed)

How to apply patch

1. Download appropriate patch (e.g. /home/unsacrificed/Downloads/fix-ms-mouse-scroll-4.0.5.patch),
2. In terminal cd to directory with your kernel sources (e.g. cd /usr/src/linux-4.0.5-gentoo),
3. Apply patch with patch -p1 command (e.g. patch -p1 < /home/unsacrificed/Downloads/fix-ms-mouse-scroll-4.0.5.patch),
4. Rebuild and install your kernel as usual (no special kernel configuration needed).

How to view usb device vendor id and device id (aka product id)

1. Find it in kernel log

   Use something like sudo journalctl -k or sudo less /var/log/dmesg. Example output:

   usb 1-4: New USB device found, idVendor=045e, idProduct=07a5
   usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
   usb 1-4: Product: Microsoft® 2.4GHz Transceiver v9.0
   usb 1-4: Manufacturer: Microsoft
   

   where 045e - vendor id, 07a5 - device id.

2. Using lsusb

   Run lsusb to show installed devices. Example output:

   Bus 001 Device 002: ID 045e:07a5 Microsoft Corp.
   

   where 045e - vendor id, 07a5 - device id.

Add new mouse support

If you have Microsoft mouse with scroll bug and mouse isn't supported by this patch do following:

1. Change 0x07a5 (in line +#define USB_DEVICE_ID_MS_SCULPT_ERGONOMIC_MOUSE 0x07a5) in patch to your mouse device id,
2. Apply modified patch,
3. If modified patch help you to resolve scroll bug - let me know and I extend supported mice.

Apply patch to kernel newer then 4.3.0

Be sure that after apllying patch to such kernels in file drivers/hid/hid-microsoft.c MS_VSCROLL define have unique value over the block of MS_ defines. Multiply MS_VSCROLL defined value by 2 while it isn't unique if needed. E.g., kernel 4.0.5 has following block:

 #define MS_HIDINPUT		0x01
 #define MS_ERGONOMY		0x02
 #define MS_PRESENTER		0x04
 #define MS_RDESC		0x08
 #define MS_NOGET		0x10
 #define MS_DUPLICATE_USAGES	0x20
 #define MS_RDESC_3K		0x40

so MS_VSCROLL defined value should be 0x80 (0x40 * 2).
