ft_open_by_location

I'm using VB2005.
can somebody help me to use the FT_OpenEX function with USB physical location IDS?
Or someother tricks to manage more than one FTDI devices connected to my USB ports.


many thanks..

Use diffrent descriptions or serial numbers, which can be programmed into the eeprom.

ft_openex

thanks for your reply, but I'm using a 2232 FTDI device, in USB-dual RS232 converter configuration.
I don't think I can change the device decription as I want.
Or am I wrong?

I would like to use FT_OpenEX( dwloc, FT_OPEN_BY_LOCATION, FT_HANDLE)

where
dwloc= physical location ID of my USB device
( I try to obtain such loc ID using USB VIEW.... but may be there is something wrong in my application, because FT_OpenEX doesnt' work, as it gives me FT_STATUS=2 , that is "device not found")

does anybody know how to use USB VIEW together with FT_OpenEX and FT_OPEN_BY_LOCATION flag ?

YEP!
I solved everything!
I used FTDI MProg to set my own description and SN, so that I can select my devices using FT_OpenEX with FT_OPEN_BY_DESCRIPTION flag.

thnx!!
