Hey all,
I'm looking at rs232 controllable PTX systems, and they seem to be more and more usb and less and less rs232.
So is there anything like [comport] that allows one to send bytes to usb devices? I think a general mechanism, like [comport] that would work for all usb devices would be better than a slew of objects for each specific usb device...
Thoughts?

Nope, not possible. USB is not like a com port (even thought you can emulate a com port with USB). USB requires a specific driver tailored to the target device (USB communication is not similar to rs-232 serial communication, the main difference being that an end device can not send data to the computer without a direct request from the computer).

You could make something based on libusb, but USB is pretty complicated, so you'll want something higher level. Perhaps these devices are actually USB-serial or USB-CDC (like serial). Then they would not be hard to use, provided you have a driver to make them show up like a serial port.
