USB hub - high CPU use?
Are USB hubs supposed to take up like 20-30% of the CPU? It seems the more stuff I connect to it, the higher it goes. And yes, I've tried to just connect all the devices directly to the PC and it was all normal, so I know it's the hub and not something else.

how USB root hubs do you have
take a peek in the device manager, it'll tell you how many you have. Try to spread the number of devices evenly across the root hubs.
But if you don't need a particular device, unplug it. If something happens on a root hub, the CPU has to ask each device on that hub if it did something.

Well my win2k is Dutch, so I'm not exactly sure what they translate "root hub" to...
However, I'm not sure if this is what you mean, but I've got one external USB hub that I connect all my devices to, which would be my modem, my keyboard and my tablet (which is also my mouse), and I've got a few other things that I don't use very often and which I only plug in when I do.
I can only connect them to this external hub because I've got my PC in a different room from where I'm working.
Does this really need to take that much CPU? I've got an athlon XP 2400+, if this was a pentium 2 or something I'd expect something like this, but...

Maybe it is. I got this one.
I guess I'll email them about it. Last time I ever let the store sell me something of a brand I've never heard of, without doing research....
Edit: now that I think of it, maybe this is somehow related: at startup, the bios does not start checking ram or drives until I unplug the hub. After it's done I can plug it back in. Weird.

I have a similar issue with one of my external harddrives.blackmyst wrote:Edit: now that I think of it, maybe this is somehow related: at startup, the bios does not start checking ram or drives until I unplug the hub. After it's done I can plug it back in. Weird.
My BIOS freezes through scaning my USB ports unless I have it powered off during boottime.
Does the stuff you use include a keyboard, mouse, and modem?kevman wrote:No, certainly not.
I have a 4 port hub and use all 4 ports nearly all the time.
My computer idles at 0%.
Maybe your hub is shit.
If this is supposed to be normal for a USB hub that has all those things attached then fuck it, I'll just buy a whole bunch of USB extention cables and use those. I can hardly use my computer, what bullshit is this.
If it's not supposed to be normal, could you tell me the brand of yours?

So I made a fresh windows installation the other day, and the problem seems to have vanished. The CPU sits pretty much unused no matter what I connect to the hub. Hmm. Well, thought I'd mention it in case it might be useful to someone.

Hah. I thought I'd install my PC's USB drivers since I hadn't yet after formatting my HD, even though the USB was working properly. And guess what? Thing's gobbling up the CPU again. I uninstall the driver, problem gone again. So fuck the drivers then, it seems to work fine without them.
Or would there be any negative side effects?

IIRC most times its better off to use Windows' USB drivers that what came with the motherboard/add-in card.blackmyst wrote:Hah.

Check to make sure that your USB systems are USB2.0. Chances are, with Win2k, they are actually operating at 1.0 speeds. Easiest way is to use HDspeed
with a USB flashdrive that's 2.0. If your speed is greater than 2 meg, you are good.
