WebThis is a USB 1.1 chip. The USB does transfers using packets and not a continuous stream as for example serial. So your device will get a time sliced window and it is up to the driver to utilize this window effectively. When you set the packet size to 1 you can only transmit one byte per USB packet. WebThis is done by sending a sequence of bytes directly to the data pins (the base port address) without using a handshake. To communicate with the peripheral you will need to select one of the available parallel port protocols. You will likely want to support more than one; typically one of the newer fast protocols and basic SPP transfer.

WebTo work around this problem, asynchronous serial connections add extra start and stop bits to each byte help the receiver sync up to data as it arrives.
