I don't have any messages from You for several days,
Is You still working on my mouse wheel?
I just updated source tree and rebuilt it, but wheel don't work.
можно конечно еще попросить его пересобрать usb.ko с дебагом
и поднять дебаг до 10
в меик файл туже самую опцию USB_DEBUG
и теже самый дейтсвие с колесиком
да и еще
уточнить где и как он юзает это колесико
продемонтсрировать конфиг xorg
если я так понимаю
