problem with usb mouse

Hi there,
I have a problem in my OS with the mouse.
The mouse is microsoft USB (on USB port) and i have put at bios "mouse usb support = enabled".
When i am running my OS in VMWare, it runs OK.
When i run in the real pc, the mouse works but goes whenever it wants

Goes to different directions with a lot of speed.
The same problem exists if i put the mouse to a PS2USB adapter.

Any idea?

I tested your OS in vmware, and it's actually the same problem as you describe on a real computer. The mouse goes in every direction at once.

in VMWare v.6.0 works ok. In older versions (like 5.5.1 i have tested) works like real pc.

This is all I got when I tested it in qemu. It doesn't go past this.

This happens when you press a key before keyboard driver inits. (it's a known bug).
Except if you don't press any key while loading OS.
I don't have qemu to test it.

EDIT: But this is not a reason to stop booting.
Just reports the irq (to remind me to fix some things

)

I put at my website the debug version.
If you want, download it and run it to see where is crash.

Thanx

No matter how long I wait it doesn't go any further even when I don't press a key, it just stops.

qemu is often so fast that the interrupt on key release occurs while the OS is already running. That has happened to me many times with my OS before...

the debug v starts up, writes a bunch more info to the screen, then stops

thanks

well,...
I repeat the problem in bochs.
The problem is that the interrupt flow for the FDC does not continue after seeking to next sector.
Strange because in normal pc works fine.
