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.

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).

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?
