Bug Description
Hello,
I have an issue with a lenovo yoga mouse.
This mouse has 2 working mode either bluetooth or with a provided usb dongle.
USB dongle works fine, but bluetooth don't.
Cursor is slow and laggy.
"evhz" (https:/
Polling speed is too slow.
I tried different howto suggesting to change usbhid mousepoll value => does not help.
The mouse seems handled by btusb module, not usbhid (modprobe -r usbhid killed my other mouse, but not the lenovo, while modprobe -r btusb killed the lenovo).
I tried 2 laptops (XPS9370 with 18.04, kernel 4.18 and kernek 5.07 and an older dell Precision M6400 16.04 kernel 4.15).
Bluetooth pairing works well, either with gnome bluetooth interface or with "bluetoothctl"
Both laptops reports ~20-22Hz polling speed with evhz (and same laggy behavior)
I also tried 2 bluetooth interface on the XPS13 9370 : the integrated bluetooth and a Sabrent USB Bluetooth 4.0 (to connect with the Sabrent, I have switched off integrated bluetooth with rfkill).
