Have USB 2.0 but only says 1.1

[ss2]

I'm running windows XP pro on an Intel Dual core. 500 watt PS. I've added in a front panel USB connecteed to a PCI slot.

The USB's work most of the time, but when I plug a memory stick into them, I get the message that "this device will work faster if you use a 2.0 slot." The USB's are 2.0.

The other thing I noticed which was strange - was that if I plugged my 250GB external drive into the USB port (and also into an outlet for power) - it caused my Motorola wireless network device to NOT connect. It's as if the power required to run both just isn't there. If I unplug the HD - disconnect the Motorola device and then plug it back in - it starts working again. I use it to print to the printer in another room of my home.

Am I dreaming or just doing something wrong. I periodically get I/O errors on my larger external drives when plugged in at the same time as other things. All USB stuff. Do I need a larger power supply or do I need to somehow allocate more power to the USB ports?

Sometimes I can't read or write to these larger drives. I don't want to ruin anything.

Help?

Is this the built-in USB controller (the MB one), or an external one?

I get the same message when I plug in my Thumbdrive..I think it really means if you have Firewire it would be faster.

Actually I get the same message on both the peripheral one (the front panel which is connected via PCI to the bus and also the one ON the MB. It never occured to me that it could be looking for a firewire connection. I assumed it was referring to a 2.0 port. The message instructs me to "click here" for a list of available ports. When I do that - only USB ports show up in device manager.

mostly it's the USB that I added to the motherboard via a PCI slot. It's easier to access. I'll have to check to rear built in ports to see if they do the same thing.

This won't change. Rear and front are the same built-in ones. anyways, can you check the transfer rates (read and write) to usb drives? And again what WindowsXP system is it? Clean, SP1, SP2, fully updated? And is it any different (the transfer rate) under any Linux LiveCD?
