Hello, I have problem with USB device. I'm loading prodram to my AT91SAM7SE-EK (for example HID MOUSE PROJECT) and it wasn't work. Computer recognize the device but it can't instal. I use Windows Vista, but try on XP and Windows 7 and always was the same. Please help me.
Did you erase the MCU code FLASH by putting J5-1 jumper, described on this chapter of the user's guide ?
