I try this parameter as well. Here is what i get:
--------------------------------------------------------
USB Legacy Support | ACPI enable | ACPI disable
--------------------------------------------------------
"disable" | USB ko :( | USB ko :(
"all device" | USB ko :( | USB ok
--------------------------------------------------------

Sorry, i don't really know. I said it must be ACPI since it worked in a
past release with ACPI enable, however it may be a problem in the USB
code.
I will try to submit debugging information on ACPI as pointed out by
Anish. Are they any other tests i can do in order to know what this
problem might be?
