Hello, I upgraded to the latest official Mandriva kernel : 2.6.12-25mdk. After having enabled CONFIG_USB_DEBUG and generated a new kernel, I did not get much more informations; what puzzles me, is that uhci_hcd does not even discover the USB 1.1 added component ? could it be related to the tag "SERIAL_SSA" (see my first post) : the driver could guess that it is a SSA device and not a USB one ?
I don't know if I will switch to kernel 2.6.17 downloading the sources from kernel.org - I never did such a job before, I am afraid it will require too much work in order to get a clean kernel running ... as I would probably work in order to get the same configuration as Mandriva supplies in order to limit mistakes ... here are the relevant syslog lines with CONFIG_USB_DEBUG enabled : egrep -i '18:11.*(usb|hci)' syslog Sep 3 18:11:06 rubedo kernel: Inspecting /boot/System.map-2.6.12-25mdk_dbg_ehci Sep 3 18:11:06 rubedo kernel: Loaded 20969 symbols from /boot/System.map-2.6.12-25mdk_dbg_ehci.
