Try upgrading to a 2.6.8.1 kernel, this sounds like a host controller
issue, and not a hotplug script specific issue.
If you still have problems with that kernel version, take this to the
linux-usb-devel mailing list (detailing what USB host controller driver
you are using.) The developers there will be able to help you out.
