Hi,
When using a PS/2 mouse everything worked fine. I swapped it for a USB mouse, but this mouse isn't always detected while booting my (386-based) OpenBSD 5.8-stable system. Replugging the mouse when the system is running usually solves the problem: the mouse is detected and works fine. Sometimes this replugging needs to be done several times on different USB ports for it to have effect. Before sending this message I checked whether the mouse itself is the problem because it's a cheap one, so I tried other OSes (Debian Linux 8.2, NetBSD 7.0 and FreeBSD 10.2) and the problem was gone, so my mouse looks OK. Possibly the problem is in the combination of my hardware with OpenBSD. However I would like to use OpenBSD. :) Is this a known problem? I saw some people on this mailing list having trouble with USB mouses periodically reconnecting, but that's not my problem: most of the time it isn't detected at all. I'm sorry I can't send a dmesg right now. :) If needed I'll post one later. Have a nice day, Paco
