Hi,

I witing a program in c++ on linux ubuntu using cyusb library.

I add my device to the file cyusb.conf in etc file but my program or programs form example source from this site didn't find it.

http://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit

When I using FX3 the program see it but when I attach device with FX2 it didn't works despite the addition VID and PID in cyusb.conf.

Which may be the reason for the error?

Hello Przemyslaw Wujek,

Please check if the device is identified using the cyusb_linux utility that comes with the FX3 SDK for Linux.

Best regards,

The function cyusb_open(VID, PID) with VID and PID placed in cyusb.conf return value -19
The function cyusb_open() return value -13

Hi,

You want to write a Cpp application which can talk to FX3 device. You can refer to the Cpp implementation of Streamer application "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\cpp\streamer". If possible, please attach your Cpp application code in the Forum thread so that I can reproduce the issue.

Thanks & regards
