USBMSC Identifier (non-unique)

[Cippecciopp]

Hi, I am trying to install ML on a computer with an ASUS P8Z77 V but I receive the following error when I launch the installation from the USB device created with Unibeast:

USBMSC Identifier (non-unique): 0x5e3 0x723 0x9451

There are no USB devices connected other than the Pendrive created with Unibeast, an Apple keyboard and a mouse.

I don't know what's wrong.

A note, I cannot have only 4 gb of ram installed in the machine as my smallest dimm is 8 GB

Thanks in advance

I found out that it was due to the usb ports in my computer, I changed them and now I have installed ML. I have another problem...
Once it restarts after the installation I follow the instruction and I still boot from the USB devide, this time I choose Mountain Lion, but when it loads I receive errors, one is related to the power management that may be incomplete or unsupported (despite I have patched the BIOS) and then when it reaches the IOBluetoothHCIController][start] -- completed nothing else happens... what should I do at this point?

Great !
I have the same issue.
Can you be more specific, and tell us what did you do, precisely ?
