Slightly different USB problem with KT7-Raid

[LuZar]

My problems is different from most of the USB posts. My USB device are detect and works..to an extent. Actually I'm only use an USB Explorer mouse. It detects fine and works but there's a stutter every now and then. It'll move and then stop and after a few secs I can use it again, the light on the Device is on the whole time, and system is not frozen can I can still work with my keyboard. I've DLed them 4in1 4.29 Final Drivers.. and the USB Filter.. and nothing seems to affect it. I've tried removing all peripherals and numerous BIOS settings.. nothign seem to do anything. All this is done with clean WinME installations after a reformat. It;s works fine when I'm using the PS/2 convertor... I know there's alot of post about the board not being able to detect USB device but mines detects fine.. just the stutter is very annoying.. cant play Runes.. =\ It's not a power supply problem because I've even removed all unnecessary harddrives,fan, sound card..NICs and stuff. Maybe someone can post a way around it.

Do you have any cards pugged into PCI#4 or PCI#6? These slots are shared with the USB and if something in these slots is making a call to the IRQ, well you get the picture.

It dont matter.. all my cards seem to have no problems with IRQ sharing. I've tried removing all the cards except for video and still get this problem. Oddly enuff.. this only happened after I reinstalled Win ME. My previous ME installation never had a problem..
