power to the emulator.

Go on following the wizard, and a dialog box for specifying the setup information file (inf file) is
displayed. Specify the musbdrv.inf file stored in a location below the directory where this debugger is
installed.
ATTENTION
• Before the USB device drivers can be installed, the debugger you use must already be installed.
Install this debugger first.
• A user who install the USB device driver need administrator rights.
• During installation, a message may be output indicating that the device driver proper
musbdrv.sys cannot be found. In this case, specify the musbdrv.sys which is stored in the same
