Hi everyone,

I've had the 680i SLI eVGA T1 (I believe it's the T1 and not the A1, whichever is 
the improved model) for about 2 years, give or take. It's been fantastic, overclocking 
with no problems, changed hardware here an there, wonderful.

For the first time in my life I received a USB bandwidth exceeded error message when 
I plugged in my ABS AZ1 7.1 USB headset and made a video call on Skype using a USB 
webcam, more specifically the Namtai version of the PS2 Eyetoy. I'm running a clean, 
freshly installed Windows XP Pro SP3.

I have the following plugged into my USB ports:

front 2 USB ports:
nothing

back bottom 4:
HP Deskjet 840C printer
Razer Copperhead Laser mouse
basic Logitech USB keyboard, no multimedia buttons, just numpad, letters, numbers, 
F keys, the basics
Lite-On Lightscribe Dual Layer DVD +/- RW 16x

back top 2:
nothing

Of course, my Eyetoy is plugged in as well, but I've tried unplugging all devices, 
so that ALL 8 ports are free, plugging in just my Eyetoy and headset, and it still 
tells me USB bandwidth exceeded.

Here's the kicker - for the last year or so, I've had the Eyetoy, DVD drive, Logitech 
USB keyboard, Razer Laser mouse, and printer ALL running at the same time, in the 
back ports..and have never received that message. Do those devices really take up 
such a small amount?

I've searched for countless things on Google, but I just can't seem to find anything 
concrete, other than things pointing to install a new USB host. However, I'm not 
really willing to spend $15 on a PCI card, when I bought the headset during a $10 
off sale.

When I get the message for the USB bandwidth exceeded, I look at the percentages 
allocated, and with ONLY my Eyetoy plugged in, there is 10% "system reserved" on 
one host, and 25% system reserved on the other, which is the same host as the Eyetoy, 
which takes a whopping 60%. It says there is 12% free, which is confusing, then says 
the new device (after plugging in my headset) is requesting 16%. Now, to be only 
4% short, makes me feel like the Eyetoy should kick it down from 60% to 56%, because 
I don't need the Eyetoy's audio, and since the headset is 7.1 surround sound, as 
well as a microphone, it makes sense that the much lower quality stereo audio on 
the Eyetoy shouldn't need THAT much just for video. It's not a high definition camera, 
and because there are specifically for Windows XP 32-bit (which I have) written drivers, 
the Eyetoy should NOT need all of the functions the PS2 does, like certain recognitions 
of a person for affecting gameplay and fancy things of the like.

In a nutshell, I'm just looking for a way to be able to plug in my headset and Eyetoy 
and be able to use the both on Skype during a video call.

If I have absolutely NO options with the current hardware I have, and no matter what 
I'm going to have to spend more money and wait, would it be more practical to get 
a USB to audio plus microphone jack converter for my headset, or will that remove 
the ability for 7.1 surround sound? Otherwise, will buying a very highly reviewed 
PCI card with a few USB ports resolve my problem if I plug my headset and Eyetoy 
into the separate host ports? Is there a way to lower the system reserved USB bandwidth, 
even by just 4%?

Thank you very much in advance! I'm greatly looking forward to any contributions!

EDIT: Just a quick update - I have to Host Controllers:

Standard Enhanced PCI to USB Host Controller
System Reserved - 11%

Standard OpenHCD USB Host Controller
System Reserved - 25%
USB Composite Device - 60%

I can't figure out how to access the the Enhanced PCI to USB Host Controller..especially 
because I do NOT have a PCI card installed....how would I access it? There are 2 
leads on the motherboard but I attempted to plug in a multi-card reader/floppy 7-in-1 
drive and the drive fails to work or light up. I can't tell if it's the drive since 
I have no other devices that connect to internal USB leads.

I have an extra USB 2.0 port cable that came with the motherboard that I can connect 
to that lead, but I'm afraid to do it in case of power overload, or whatever. Should 
be fine though, considering I have a 700W power supply with extra power to spare.

Also, is the OpenHCD controller actually USB 2.0?

Seems like a hardware question. Also your Power Supply is not a factor on whether or not your mobo might be overloaded.

Wednesday, November 4, 2009 at 5:52 pm Posted by Watashi (4 messages posted) I feel like it could equally be the responsibility of the motherboard or the operating system. I mean, if there is so much that is system reserved, wouldn't the operating system have a say in that? I unfortunately have not had the opportunity to experiment with Vista or 7, but I definitely will in the future. However, I can't have a $30 device laying around for months just to see if it will work. I need to fix this issue in XP before the 30 day exchange period runs out. Thank you very much for your fast reply!! [Reply or follow-up to this message] re: USB Bandwidth Exceeded - 680i SLI BIOS fix? Thursday, November 5, 2009 at 12:09 am Posted by Kevinh (634 messages posted) I agree with Ricer46 this has nothing to do with XP, BIOS and USB controllers are part of the motherboard chipsets, drivers can be detected and installed as part of an initial XP install, if youre lucky, but device drivers are not considered as being part of the OS.
