Well I will give it a try when I have the device at hand. I still cannot classify the different modules: There are chipset dependent drivers like Cyriac Benoit said: ohci, uhci and usb-uhci. Ok. Then there is the ehci driver (ehci-hcd module). Is this driver number 4 in the sequence of chipset drivers or does it serve a different purpose and relies on any of the ohci, uhci or usb-uhci drivers? If it servers a different purpose than the other three modules I do not understand the posting for which I gave the URL in my last mail since there was talk about a working uhci driver but an ehci failure for the device. Because of this posting I thought that ehci-hcd is another implementation for the same purpose like the uhci module. But this does not fit to what Cyriac Benoit said?
