PortableApps Menu -- Autorun.INF Getting Blocked

When I plug my stick into a 1.1 port, the XP generated error msg: "This device can perform faster ..." jumps in before or instead of the PA Menu Autorun.INF. So The PA Menu tray load gets blocked and nothing appears in the tray.

Is there a Q&D workaround for this, or is it s.t. for which a slight programme tweak possible?

[I have a few older ThinkPads I can't bear to part with which usually have USB 2.0 PCCards stuck into them at home. Not always so on the go. This might also be an issue for anyone stuck using PA on an older machine.]
