Hello,
I have the same problem with a Logitech Rumblepad 2 wireless, like on usb3, I tested with a gamepad noname (included with my DSL box) always the same, someone found the solution?
For me it totally blocks the boot to the first page (listing materials) 2 keyboard and 3 mouse (which is a gamepad) against each other by the 2 nd mouse and keyboard,
I don't know.
I have a Logitech G15 refresh, razer mamba, multifunction printer plugged in but not turned on, and an external hard drive plugged in but not turned on, all on usb2.
thank you in advance
