Hi tiziano,
I thought the kernel should work in the same way in Live mode than in full installation but it seems it can be different. I'll have a look to this later. Anyway, it's always better to test a new ISO (particularly mines ;-) ) first in Live mode and then install it. For the moment we are going to work in Live mode and if we succeed we'll see how to modify your existing installation.
Boot again with my ISO and run, in a terminal, as root
modprobe uhci_xcd dmesg | grep -i uhci
Look for error messages; post them if there are.
At this step you can also insert a stick in one of the USB 1 port, run
fdisk -l
and see if it is detected (should be sda1
)
Test your USB ports the one after the others.
Repeat these steps for your USB 2 controller:
modprobe ehci_xcd dmesg | grep -i ehci fdisk -l
