Hello,
I am using a DIY KVM switch system. While the HDMI switch is no problem at all for now, the keyboard and mouse were switched using a cheap USB2 Hub... and this became a problem.
Some time *after* the last switch the keyboard and mouse silently failed. I switched them to a different USB2 port and they worked for some time before failing again. Now no USB2 port would take them, either through the hub or apart, but I put them into USB3 ports (apart, without the hub) and for now they work again. If I detahc the mouse and attach to a USB2 port it does not work. Back to USB3, it works.
I am looking at dmesg output but not understanding anything.
In this excerpt, "usb 1" is the USB3 port, after that connection the mouse works. "usb 3" is the USB2 port, after that connection the mouse does not work. I am failing to see the difference.
You could try something as basic as usbmon (https://www.kernel.org/doc/Documentation/usb/usbmon.txt). If this will show traffic between mouse and HCI, you could then try evtest utility to see if kernel input driver works. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
