USB Devices keep disconnecting

Specs: Windows Vista RC1, 1 GB

I keep having this annoyance issue with both Windows Vista and Windows XP. I have all my devices currently attached in seperate usb slots however everyone now and then, all my devices disconnect and reconnect(in a few seconds). I wouldn't care about this issue so much but whenever it does this, a message shows up saying that my devices can go faster . So all my usb devices have just been reduced to USB1.1 and transfers slow down. The only way to fix this is to restart the computer. Does anyone know what may be the problem or how to fix this issue. Right now, i have just my usb hub (with just a mouse one it) and my printer connected directly to my laptop. I have tried only connecting one at a time but it seems to occur with every device.

Try RC2, it may be a bug that has since been resolved.

Since you say it is also in windows it may be a defect in the motherboard. It also may be that the current sense is showing too much current draw. If you say you keep the hub on then it might still be the cause.

I read it wrong and answer it wrong too. So get off my case you goober.

So your saying that the hub is the cause so if i connect everything directly it might fix the problem? If that fixes the problem i kinda of need a hub because my usb ports are limited. What would you recommend for a good usb hub.

Dunno, can't say for sure from here. I only offer some suggestions.

Test and use diagnostics to determine.

There is no "high quality" hub that I am aware of. Before you buy anything you might consider the solution you posted about. It may be a driver issue with that hub and not exactly that it is defective. Might be a bios setting but unlikely but could even be a bios update that exactly tells of this issue. Do not update bios unless that is the case.

If you have an empty PCI slot in your PC, then you can buy and install a PCI-to-USB card. This card offers both USB2.0 and firewire or only USB2.0 connectivity. It comes with 5 or 6 USB 2.0 connectors. And you do not even need drivers because Win XP sp1 or sp2 has the drivers.

You are not limited to using a USB hub.

For notebook users, there are PCMCIA cards offering USB connectivity.

My old PC had only USB 1.1 connections. I bought a PCI-to-USB 2.0 card and made my PC USB 2 compliant. I even disabled USB on the motherboard and used only USB on the PCI card.

I could do that but my laptop already contains USB 2.0 ports so it would be unnecessary. I'm going to try so trial and error techniques and connect everything directly to see if it fixes the problem. If so, i guess i'll have to live without a usb hub.

Thanks for your input
