USB Problem

I have an intermittent fault with my usb. Everything in device manager looks fine. The problem is that the only way I can get a connection to the internet (i have a usb ISDN modem)is by unplugging the usb connector and then plugging it in again!

I also get the same situation with my scanner. In the middle of a scan it stops responding but it only happens intermittantly. I carry out the same proceedure as above and it works fine, for a while.

I found a similar problem on a usb forum and the question of the power supply kept coming up. I fitted a new 550w supply yesterday but the problem persits.

If anyone can help I would be most gracious as it is doing my head in!

There's a 500mA current limit on the USB port which your devices are exceeding.
You can work around the problem by installing a separate USB PCI card - use a USB2 cardThey cost around £8 from ebuyer.
Connect the modem to the motherboard USB and the scanner ,other devices to the PCI USB card.

Thanx Newuser.

I did not mention in first post but did that last week! Got Q-Tec usb2 board from PC world. Made no difference. :-(

Ah ha. After scratching my head for a while I re-read your post as some times one can't see for looking. I will now try your suggestion and see what happens.

Thanx again and I'll let you know what happens, in a mo.

Well it took me a little longer, only because I was called away but at the moment it is looking good.

Thanx again Newuser, you 'hit the nail on the head.'
