hardware question

Should there be two things using the same IRQ?

I have NEC PCI to USB Open Host Controller and Radeon 9700 Pro both on
(PCI)19.

I also have NVIDIA(R) nForce(TM) Audio Codec Interface and Standard OpenHCD
USB Host Controller both on (PCI)21. Will this cause problems?

The reason i ask is this.. I had a razer diamondback mouse that would
disconnect from usb, and connect again by itself, constantly. so, i'd be
playing a game, and my mouse all the sudden dies completely, for a few
seconds until it connects itself again. it only seems to happen when i'm
playing games so far. i thought it was the hardware(razer mouse), but now i
have an old logitech usb mouse hooked up and it's doing it too. I have
reformatted and reinstalled windows fresh. It didn't fix the problem. Could
the IRQ thing be the problem? Or, is my USB hardware failing on me? I
haven't had problems with any other USB item other than my mouse. the damn
mouse... it's crippling as far as playing games.

Which version of Windows are you using? Generally, 2000 and XP share
resources without any problems. Earlier versions also could do this, but
frequently had to contend with non-plug and play hardware which could not be
automatically configured properly. That's why earlier versions of Windows
would let the user change or assign resources based on the user knowing that
some component *had* to have a certain IRQ or I/O setting to work. This
usually isn't the case with hardware/peripherals purchased in the last 3-4
years. Do you have some other hardware that isn't plug and play that could
be causing a conflict? Does Device Manager show any problems? Maybe your
motherboard drivers need updated, or you actually have a physical problem
with your USB connection.

As KCB said, there *shouldn't* be any problems, and most devices work just
fine sharing an IRQ. Your hardware may be one of a few exceptions. Do you
have the latest nForce chipset drivers for your motherboard?

I suppose you tried using another USB port on a different channel? If the
USB port is on a PCI card, move the card to another slot.

In BIOS, disable any ports you are not using, in particular "legacy" devices
like parallel and serial ports, the floppy drive connector, etc., to free up
IRQs.

I have heard of similar problems with the razer d.
some have to disconnect the mouse manually and reconnect it to make it work.
stops working in the middle of the game.
I was about to get one, but after what my friends told me about theirs, no
more...
I think it is a mouse problem, not windows or computer.

I think the problem is gone!! The most unsolvable problem i have had yet
with a computer since 1997. It feels good to have it taken care of... Thanks
for all the help!! It was an IRQ problem i assume, because i had a USB card
in there, and just switched PCI slots. I also disabled serial ports and one
other thing i believe. I was having problems with both the logitech and the
razer mouse. So far, after a whole night of gaming, i have had problems with
neither, and so i have my Razer on here again.

Most unsolvable problem since 1997? Imagine the dark ages before
plug-and-play... Anyway, glad it worked out for you.
