Any hints where to start and what to look for? I bought this mouse because it was really silent and cheap (APOINT M302) and it was working with Debian Jessie. https://www.aliexpress.com/item/New-Bluetooth-Ultra-thin-Rechargeable-Wireless-Mouse-Silent-Button-2015-computer-mouse-for-laptop-gift-mice/32368987723.html?spm=a2g0s.9042311.0.0.27424c4dCuQb1a Officially Linux support was not mentioned, so it might be difficult to find a drivers for it. I wonder what was changed between Debian releases that this mouse is no longer working correctly? For me looks like a regression which should be fixed. Should I reported this as a bug? If "yes" then which module/driver should I specify as a victim? > Can you get any other bluetooth device to pair and > actually work with the dongle such as a headset or keyboard? Yes, I was able to successfully connect some remote controller/gamepad which also has mouse option: https://www.amazon.de/ddLUCK-Universal-Wireless-Controller-Bluetooth-Remote/dp/B01ICYZ7ZI/ref=sr_1_12/262-6869085-0156757?ie=UTF8&qid=1527838130&sr=8-12&keywords=mocute Maybe I should also try with another BT mouse to see if it has the same issue or not. > There are a lot of moving parts here such as the usb > driver for the dongle and then there is the communication between > the bluetooth device and the dongle. > > dmesg and syslog are very good tools in cases like this > but the messages you will read aren't always the answers to the > question of why this or that is happening.
