Problem has been introduced in Lucid on my AMD64 workstation. Prior to upgrade, both Free Agent drives work properly (though they would sleep and disconnect).

The USB 2.0 module appears to behave well with some devices - my printer, DVD-R drive and select Flash drive work - but very poorly with others like other Flash drives and the aforementioned Seagate external hard drives. And at least with my workstation - the problem appears to have been introduced with Lucid.
