As an example i used the Automator project but i am a little bit confused about the maximum bytes per packet. VUSB implements a low speed usb device. As far as i know the max packet length of low speed devices is 8 byte but in the Automator projekt a report with a length of 129 bytes is described! Would be fine if it works but unfortunately i get only the first 8 bytes. All other bytes have random values. Can anybody help me?

Best regards
