USB_ERR_IOERR: a proposal solution

[ingegneriaforense at alice.it]

During the freebsd installation I
receive some messages:

>> usbd_req_re_enumerate:
addre=3, set address failed (USB_ERR_IOERROR, ignored)

>> usbd_setup_device_desc:
getting device descriptor at addr 3 failed,

>> USB_ERR_IOERROR ugen0.3:
<Unknown> at usbus0 (disconnected)

>> uhub_reattach_port: could not
allocate new device


These messages appear during the whole
installation process overwriting the monitor and this also happen
when the sysinstall windows are shown.



THE SOLUTION: To solve this tedious
problem i've disabled in the BIOS the "USB 1.1 OHCI Controllers"
that prevent the "USB Legacy" option. No devices I have plugged in the USB ports (I've used old PS/2 keyboard and mouse).

THE QUESTION: please, can you tell me what this
means ? 
It means
 the HUB is unable to enumerate some device, because it is not 
responding correctly to the USB tokens the host controller is sending. 
But for an hardware problem or maybe the Freebsd kernel does'n support the USB Legacy ?
Thanks in advance.
