I don't think this problem has anything to do with your cardbus controller. The log shows the Handydrive failing to reply to all WRITE commands, so probably there's something wrong with the drive. It's also possible that you're seeing some sort of interrupt handling problem. But that is less likely, because the log shows the drive working properly following a reset after the failed WRITE. So far as I know there's nothing buggy about high-speed support or USB-2.0 support in Linux -- but there are a lot of buggy devices!
