I'm not using a english windows version but I think the translation would be "This device can perform faster". It could look like this
I've tried all USB ports on three different computers. All symstems were WinXP SP 3.
So, I thought it was a problem of this device (S/N 157391). So I bought a new one (S/N 157400) , but the same problem there.

How to solve this?
