ahearnb 0 Posted May 26, 2001 Hi, I've got a Microsoft Explorer mouse and have installed the drivers for it. When I plug it into a USB slot, it works until I restart. The computer will not boot up completely and hangs before it gets to the desktop. I must have something plugged into my PS/2 slot. I am running WinME at the moment (because of a game), but the same problem exists with Win2k. Does anyone know why? Or what I could do to fix the problem? Thanks! Brad Share this post Link to post
badboy 0 Posted May 26, 2001 Have you tried to disable PS2 support in the bios if your motherboard supports this function plus see if you have in the bios a funtion to enable usb legacy support for keyboard and mouse if it has enable it !!! Share this post Link to post
DrPaulFlammond 0 Posted May 26, 2001 Optical Mice have an occasional problem with onboard USB. Their current requirements are 100mA. Most onboard USB ports can barely supply that at their maximum. My 840 will not boot with an optical mouse in USB because it can't talk to it properly due to the power problem and decides theres no mouse and freaks. It's unusable on my BX due to excessive lag from the same issue. Still lags in PS2 on the bx, but seems ok in PS2 on the 840. I haven't verified, but I'd wager if you had a USB hub (they normally can supply 400mA) it would function just fine. -DPF Share this post Link to post
ahearnb 0 Posted May 28, 2001 thanks for the suggestions guys! unfortunately, i don't think i'll be able to get this thing working. i checked by bios and the USB Host controller is enabled as well as the USB Keyboard support. IRQ 12 (PS/2 Mouse) was also disabled...i even tried enabling it to see if that would work. any other ideas? Brad Share this post Link to post
Brian Frank 0 Posted May 28, 2001 I have an optical USB mouse, but I use the PS/2 port for that and save the USB ports for other things. Just my take. Share this post Link to post
fist7 0 Posted May 28, 2001 i use my intelli mouse explorer on the ps2 port too and there aren't any problems - only the lower refresh rate usb has 100hz, and ps2 40 or 80, don't know exactly, for win9x there are tools to set this to up to 200hz - does anyone know of such a tool for win2k ?
