David: The context here is that the DiMAGE A2 camera only sometimes responds to SET_ADDRESS -- and only when UHCI's Full Speed Bandwidth Reclamation is turned off. Do you have any idea what might be going on? Can you think of any way to make it work with an EHCI or OHCI controller?
Sven-Olof: On this computer, you could try out the OHCI controller simply by plugging the camera into the USB 2.0 port after unloading the ehci_hcd driver.
