My computer is Windows 7 and I use the usb driver in the disk in win7 directory,it can not work. But when I choose usb driver in Vista directory it works. But there is another problem,I start my AVR studio 4.18 and press Com button, I choose AVRISP as document said,and I can not choose the com13 my computer intalled usb driver,it can only choose to com9.
Yes, the driver is a little shitty, but works.
and the AVR studio just can select the COM1~9, please change the COM Port in the device manager.
