Thanks for the detailed information, that allowed me to add an experimental backend for the M721 in 6f0a4ad. If you make sure to build from the master branch, it should hopefully be no longer required to use the --bus and --device options, additionally when using -R the correct model should be displayed at the beginning.

If everything works, i expect that there a still two main problems:

• The way the buttons are read and interpreted might be swapped. To fix this simply post the output of mouse_m90 -R - and the correct mapping.
• There will be no actual DPI values used, only the raw bytes. To fix this use the official software to change the DPI to some value, then run mouse_m90 -R - to get the corresponding bytes. Use this method to create a list for all possible values as there sadly is no linear mapping between DPI and bytes.

If there are any problems, please tell me.

Greetings. Thank you again for your work.

Today I had to use the program again to change the dpi value in my main profile number 1. Unfortunately, the official program on Windows does not allow you to conveniently adjust the desired dpi values, because the selector is very sensitive and they are very easy to miss.

First of all, I want to note that you correctly said that dpi values are encoded under certain values.

Below I will describe my sequence of actions (RS will then mean Redragon software):

1. In the beginning I reset all mouse settings to default via RS and recorded these mouse settings in m721-win_redragon-default.ini.

2. Then I changed the polling frequency values in each profile from 500 to 1000 hz and wrote the settings to m721-win_redragon-pollrate_1000.ini. The screenshot at the beginning of the issue refers to this stage.

3. After that, I changed the DPI parameter 1 in the first profile from 1000 to 800 in RS to get this encoded value and wrote the settings to m721-win_redragon-pollrate_1000-profile1_dpi1_800.ini.

4. Next, I made the desired DPI settings of the first profile in m721-pollrate_1000-customdpi.ini config and wrote these settings to the mouse via mouse_m908. At this time, the following warning was displayed 4 times in the terminal: Warning: Unknown DPI value 0xbc00
   (In RS, this value in the DPI5 of each profile is 16000.)

The recorded settings work correctly on Linux and Windows, but if you start RS again, all mouse settings will be shifted and you will need to manually edit or reset the settings to default. I decided not to edit anything and just overwrite the settings that RS read from the mouse again, and then saved these settings to m721-win_redragon-reapply_mycustomdpi.ini.

Additionally, I will attach an archive with configs and a screenshot from RS with default DPI values:
