Hi All!
I  would like to use the asio library to communicate through usb with some devices.
I looked the documentation, and searched the internet. It was said that it can be done, but I could not find any specific information.
I found a code for (old) serial ports, it mentioned the usb, but nothing more. I think the important parts were:

boost::asio::serial_port port;
port.open(devname);
port.set_option(***);

where one can set these options

boost::asio::serial_port_base::baud_rate, parity, character_size, flow_control, stop_bits

Are these option also available for usb ports? For example the data flows (found by be) are not the same.

Thanks beforehand for your reply and help.
