Funny mouse issue

I bought a new mouse. It’s got several modes, but the one I’m talking about is the wireless dongle mode where you plug in a USB thing and it wirelessly communicates with the mouse.

The new mouse runs perfectly in that mode on a Raspberry Pi 2 running Raspberry Pi OS. But, even in the same specific USB port, it does not work on RISC OS running on the same Raspberry Pi 2.

I find that strange. Other USB mice, both corded and wireless type USB, work fine under both Raspberry Pi OS and RISC OS running on the same machine.

I don’t know why this mouse is special. When I run this mouse on RISC OS, the pointer instantly goes to the edge of the screen. Mouse buttons kind-of work, as in menus pop up, but it doesn’t quite seem that the buttons always work or that it’s responding to the right button.

Has anyone else seen this?

It may be that the mouse doesn’t work in a standard way and the Pi OS drivers know about this and work around it. It sounds like the devices description of what it is sending is different to what it is actually is sending.

If you get !usbdescriptors from the page linked and send me the usb descriptors for the device at the email address on the ftpc page. I’ll see if there is anything unusual.

To get the usb descriptors double click an the app then type ‘usbdescriptors usbn’ where n is the number of your device shown in the taskwindow.
