I am not alone then...

I used a Creative MuVo 64.

Is ehci compatible with ohci? Or does it get rejected later?

The mix of drivers are confusing... Is usb-uhci rejected? Check with lsmod.

This is exactly what I get (2.4.20). But I use quite different hardware. STPC Atlas (100MHz, for an embedded project)

Our suspects: * Power consumption of device related to how much we can drive. (but this should not be a problem in your case) * BIOS/Linux memory IO mapping - cachable... e.t.c. * Something in the driver, - a timing mismatch with the HW that was used to develop the driver? - a corrected hardware bug? (we got the driver to work with the USB memory unit on another PC with ohci - so we had almost accepted that the driver was correct... but now...)
