Plugging in a USB mouse disconnects the PS/2 one

I always used PS/2 KB and Mouse and a USB KeyPad (Genius ErgoMedia 500 Gaming Explorer) to play some games, MMORPG, FPS, etc.

I have a USB mouse that has 4 extra buttons, and I need more. If I plug in the USB mouse and disconnect the PS/2, everything is okay until I touch the mouse. If I do so, the ErgoMedia goes off, then on, then I move the mouse or press a button and it happens all over again.

Yesterday, I bought a new mouse that I liked, also a USB mouse (NPlay with macros and all that stuff, 3600 DPI) I was hoping that the problem was only with the other mouse, but no.. It does the exact same thing, ErgoMedia keeps disconecting and conecting every time I touch the mouse.

What I already did:

Updated drivers of both mouses
Updated drivers of ErgoMedia (no specific drivers(Windows based))
Updated drivers of MB Chipset (Actualy no, cause it was up to date allready)
Tried other USB Ports (4 Ports back, 4 Ports Front and even 1 Port in 16 card slot device)
Disabled the "Allows Windows to shut down the energy, etc." thing in Device Setings.
Looked up in the Device Setings only apear a problem on the ergomedia (Human interface Device) when I move the damned mouse
Used Everest to read the behavior, everything normal, excepts the disconecting thing, but no errors.
Ruled out the power suply, only the ErgoMedia and the mouse are in the USBs, and I already disable the 16 card reader with one USB slot to see.
Cleaned the IRQ registry.

Try this, connect a usb hub to the PC and then connect the new mouse to the usb hub, see if the strange behavior stops.

i went crazy trying that cause it was something that i didn´t tryit, but, same problem, my uncle even borou me a charged HUB but same thing again.. What i hate most is one friend from work and my uncle have the exact same ErgoMedia and now the exact same mouse. One is using Window 7 other Vista 64b like me.. The difrences i thing is the stupid microsoft upgrades, or maybe something that i instaled, i don´t know. Im starting to give up.. I try in my laptop, an HP whit Vista 32B and in 2 sec it´s fine. But tankyou very mutch for ur concern, apreciated a lot! – Lasanha – 2011-02-26T15:41:10.613

Heres an idea; Get a USB to PS/2 adapter, such as This One. This will let the PS\2 mouse funcion as a USB mouse. As long as your computer will let you have more than one USB mice connected at a time, then this will work.
