Re: USB ?

Hi,

this is not possible. for USB communication you have to have a kernel mode
device driver for the USB device.
Is it a device that you made yourself? if not then you either need the
device driver, or the USB protocol specification for the device so that you
or someone else can make a device driver.

There are some chips available (from TI or FTDI for example) that can be
used for making USB devices appear as virtual COM ports, but that is only
useful if you make the devices yourself. they will not help you communicate
with an existing device.

If your device has a device driver but no api, you can invoke win32
functions createfile, writefile, readfile and deviceiocontrol to communicate
with the driver. you still need the driver interface documentation in that
case.

kind regards,
Bruno.

Hey
I have some device connected to USB is there any simple way to communicate
with that port ? Any free libraries / open source library or something
like this ? I saw System.IO.Ports can now communicate with COM ports. Is
there something like this for USB ?
