This is what I get on a hardy Install on a ASRock 939sli32 eSATA2 mobo.
I have exactly the same hardy on an IBM T40 notebook, where the symptom never showed up.
Kernel: 
ASRock  2.6.24-24-generic #1 SMP Wed Apr 15 15:54:25 UTC 2009 i686 GNU/Linux
T40  2.6.24-24-generic #1 SMP Wed Apr 15 15:54:25 UTC 2009 i686 GNU/Linux

I had the problem to use a garmin etrex venture hc, firmware 2.70.
The notebook was connected to a hub which was connected to the GPSr. With or without hub, the device would always show up. With dapper perfectly, with hardy I hat to 'lsusb -t' first, when connected via hub.
The ASRock was connected directly to the garmin when the above dmesgs showed up.
I then connected the hub, using the same cable, and it worked. This time it worked with the ehci driver.

The hub is powered optionally. The notebook was not able to drive an external disk when connected via hub, so I bought the power supply.
Up to now, I did not test on the sli32 with this hub unpowered as that's no option for me.

If you ask me, this is a hardware rather than a driver problem. USB is
cheap. :-)
