I am using a PS2 keyboard and a usb mouse. The keyboard has a usb connector which I connect ton one usb port of a1 and then I have the mouse connected to a usb input provided on the keyboard. Do you think that this matters?
I got USB PCI card.
i had terrible stability issues with my SAM and my peg after update 3 and onwards once USB2 support was added to the system. under heavy CPU loading -- such as browsing using MUIOWB or decoding a high-resolution video -- i would get random freezes.
turns out the issue was the USB stack not getting enough CPU time (or something) and not 'seeing' my USB keyboard/mouse for certain periods. it then deleted the devices from its tree, thinking they had been disconnected when they weren't. others have reported similar problems with USB2 support in conjunction with USB2 PCI cards using the VIA VT6212L chipset.
the bottom line is that i disabled EHCI support in my kicklayout file. this means reverting to USB1.1 speeds, but i got stability back. try editing your SYS:Kickstart/Kicklayout file and commenting out the line 'MODULE Kickstart/ehci.usbhcd' and see if that helps. it sure helped me.
