Hi, we connected the EEG-SMT board to the laptop with Win10 system and have updated it to FTDI VCP 2.04.06 driver following the manual(in Properties it says the driver version is 2.4.6). Initially the USB Serial Port was in COM 9 and we manually changed it to COM 2 which was not used by other devices. Then we opened up ElecGuru and selected the COM 2 Port. But the error message pop up was
"Can't open the serial port. Another program may be using the port, or the wrong port may be selected on this program's Preferences: Hardware menu".
We also tried BrainBay, but it also told us that that COM Port is not available, even when we changed it back to COM Port 9. We are not sure what might cause this error. Any advice would be appreciated! Thanks!

You can use newer driver, just get the latest from here (there are two first links in the table down in the page, depending whether your run 32 bit or 64 bit Windows 10):

Also try to change the port to COM3 or COM4.

Let me know how it goes.

Hi LubOlimex,

Thank you so much for your quick reply. I actually ordered two EEG-SMT boards and the one I used has the Com port error from the beginning. It turns out that the other one board works very well with the same method and laptop. I wonder if I could return the first board to you and get a new one for exchange. Thanks in advance!
