Hi, everyone.
I find uhci,ehci,ohci and usbtest modules in grub2. It seems grub2 has some basic usb support.
I want to utilize these modules to emulate usb devices plugged on my computer.
So i enter grub command line mode and insmod uhci/ohci. After i insmod one of these modules,
i get message like "disk hd0,msdosx not found".
What's wrong? Hope someone can help me.
