Are there any write or read commands for the USB port in labview,
without using the NI VISA driver developpement tool, because my unit
already has it's own drivers

My USB unit uploads firmware and then uses a driver so we can
communicate with our software.  I would like to know if there is a way
to send read and write commands to the device using labview.  In one
of your tutorials you say that to communicate to the unit no driver
must be installed, but we need to upload some firmware and then we can
communicate with the device to make our system work.  Do I need to
create a different driver so that NI-VISA can communicate with the
device or there can only be one driver that has al the
functionnalities.
