USB Hub disconnects

Sep 24, 2004 12:41AM PDT

I am running XP Home, on a system which has only 2 USB ports, so I have added a 4 port hub, with its own power supply. When I put a wireless mouse on the hub, it kept disconnecting and reconnecting every few seconds - not good behaviour for a mouse! So I took it off and put it on a PS2 port, and fixed that problem; however, the hub still disconnects at the same rhythm. There is only a printer connected at the moment. Device Manager says it is working OK, but obviously it is not.
Any ideas?

There are notes about such at http://www.usbman.com

I'd look at that power setting noted there first...

Unfortunately I get a 403 forbidden error message when trying to access usbman. Would it be possible to get to the usbman notes another way?

Try usbman later, but my hint remains...

1. Only the latest machine BIOS or don't complain.
2. Only the latest motherboard drivers or don't complain.
3. Look at any power saving settings and disable.
Hidden deep in propeties and tabs in the Device Manager and not always in the same place so YOU get to fish for it.

4. http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=+site:www.usbman.com+usbman

Tried all that, thanks; and downloaded an update from Microsoft in case it was an XPSP1 problem; didn't help. I've also connected the USB hub to my IBM Thinkpad and found that the problem does not occur with it. I saw somewhere that VIA mainboards ( which I have in the PC) have this problem with USB hubs. So that may be what it is. I can't find a fix on the VIA forum site. Any thoughts on this?

The USBMAN site had sections about VIA issues. If you have this issue, the fix is usually to add the PCI USB CARD or in the case of a laptop a PC-Card USB.

There is usually no other cure.
