Comment 338 for bug 88746

At the moment I'm running OpenSUSE 11.0 with kernel 2.6.25.16-0.1-default (x86_64) and observe the same behaviour (USB Controller is an ATI S600, by the way).

Whenever I plug in any USB-2.0 device (hard disk, flash memory or external DVD burner - doesn't matter what)
it takes quite a while until the device is mounted, and all these guys are mounted only in full speed mode.

With usbview I can check, that the high speed devices are connected first to the EHCI hub and become accessible as soon as they are passed to one of the OHCIs.

The ehci_hcd seems to try hard to catch the devices, so I get the well-known messages.

Is it meaningful that the error message changes betwenn address 4 and address 5 while the error code remains the same.

Yesterday I tried a kernel compiled on my on (2.6.26.5-default) -- no improvement at all.
Using kernel boot params "acpi=off noapic nohpet" etc. -- no effect.

I use the hard disk just for syncing with unison so I could live with that. But I am really embarassed for the low speed behaviour of my DVD burner :-(
