Re: EEG-SMT USB Interface

On the FTDI website, it offers drivers to read it as a standard USB device
via a DLL or .so instead of a virtual com port.  I installed libusb-win32
and with my Java application, I am able to see the device EEG-SMT on a bus
scan.  Though when I read from the device, the data is definitely not
correct.  This does give me some hope to use libusb in Linux, but not being
able to read the device is discouraging.  Though I will try to install the
Linux FTDI drivers and see if I can read it that way, but apparently I have
to change the EEPROM to do so.

 

Anyway, I'm not 100% convinced that I can't read it as a standard USB
device, but I haven't gotten it to work yet.  

 

Also, I haven't tinkered around with Arduino.  Where would I find this code
to which you refer?

No, you can't make the EEG show up as anything but a serial port. The COM
port behavior is a hardware thing. Specifically, it's an FTDI chip. You'd
have to ask the user which COM port it is, similar to how the arduino
environment does on the older boards. In fact, it's the same chip, so you
could probably use a lot of the arduino's code.

Is it possible to set the USB interface on the EEG-SMT to be a generic
device that is not a COM port?  

 

I've written a Java based EEG reader in Linux for Stefan Jung's EXG2, and
I'd like to also use the EEG-SMT.  The EEG-SMT does not show up in a USB
device scan, so I'm not able to discern the vendor and product ID.  

 

I don't have a lot of experience in writing device drivers, so apologies in
advance if this has already been covered.
