It's probably way off base, but are you sure that you have an ehci USB
bus? When troubleshooting USB on my machines I usually compile up UHCI
and OHCI as modules and try each one, one at a time.
how can I know ?
I have 4 usb plugs on my laptop.
here is my "lspci -v" output :

I removed everything from /etc/modules, but I still have ehci loaded
after a reboot :
$lsmod
soundcore 9952 0
ide_cd 39360 0
cdrom 35872 1 ide_cd
ndiswrapper 60792 0
ehci_hcd 25088 0
usbcore 101012 3 ehci_hcd
ntfs 86932 0
8250 17920 0
serial_core 22016 1 8250
I don't know what triggers it since I don't use any usb devices.
How can I try uhci ?
just modprobe ?
Can I have both uhci and ehci loaded, without confilicts ?
Thanks for your help
Marcos
