Non-Mac Keyboard + Mouse

[SeaDaddytheRed]

Hello, First thank you for this idea. It is exactly what I have been looking for to solve my multiple computers/one keyboard mouse setup.

I am having some problems though.

1. I am using a non-Mac keyboard, 87 key US, and I don't know the shortcut to switch connected devices.
2. No matter what mouse I connect to the pi it shows up as a mouse in the drop down menu of your program but it doesn't work at all on the computer. I have tried wireless logitech, and my Anker gaming mouse, neither work.
   Thanks again for this great idea. I hope I can get it working!

Same issue here, the filter removes all 8 byte commands:
https://github.com/ruundii/bthidhub/blob/master/mouse_message_filter.py#L10

These include all the movement events of a mouse...

I commented out those lines and the mouse works, however the vertical axis is 10x more sensitive than the horizontal axis. The result is that moving the mouse up/down is only just usable at the lowest sensitivity, while move left/right results in the cursor jumping up/down as it moves along because it picks up every little movement on that axis.

@ruundii Do you have any advise on how to debug these issues? I can see a couple of things that stand out, but not sure how to actually change them.

For example:

• bthidhub has the X/Y logical minimum/maximum reported as -2047/2047, while my mouse connected to it reports -32768/32768.
• The events from the mouse on the rpi begin with 8 00, but the events from bthidhub begin with 9 03.

But, I have no idea how to change the values sent initially.
I've also tried changing the prefix in MouseMessageFilter, but this just results in the events not getting sent at all.

OK, I managed to update the sdp_record.xml, at which point the mouse works properly. I don't think there is a "standard" mouse config you can provide in the sdp record, so it would be better to look at dynamically creating one.

Let's track this in #23, which should resolve the issue.
I've described a workaround here: #11 (comment)
