My 4 year old AcerPower FH has been doing some very strange things. I wrote a while back about my disappearing and reappearing slave drive. I have pulled it from the system for now.

Another problem has been that it very often won't power on. I have to push the power button repeatedly and then it will suddenly power up.

Today I discovered that if I unplug all usb devices it will power up. I'm sure tomorrow it will be different.

I looked on the Acer website for system drivers and it appears they have stopped supporting it.

Another thing - when I plug in a usb device I always get a message that this device would be faster if plugged into a usb 2.0 port but they ARE all 2.0

Hello and welcome to Bleepingcomputer.


The warning you are getting about USB 2.0 is really being displayed because you are using the USB port that is most likely on the computers front panel, these ports connect to the motherboard through a set of thin wires that are insufficient to carry data streams in two directions sufficiently without bottle-necking.

This problem is common with desktop computers, but not with laptop computers.

You will find that this warning goes away if you use the USB port that is incorporated into the motherboard.

Since USB ports on the computer case, usually use small cheap wiring harnesses, they can not carry as much data as a larger gauge wire, the length of the wires makes a difference as well.

To correct this problem, connect the USB device to the port that is DIRECTLY soldered to the motherboard, this port would be the one on the back of the computer case.

If you post your computer make and model number, I will try to find your driver support pages for you.

It's an AcerPower FH desktop running XP pro 32 bit. Thanks, Bruce!

I get the warning also with them plugged into the rear ports. Maybe the drivers for the motherboard will fix this?

Okay, if this link works correctly, this should link you to your drivers.
