USB superspeed peripherals

Hello,

I designed a camera that the video stream runs on a UVC driver and the command interface on the control channel uses the Cypress fx3 example device 1 driver (I used the guide to install it).

It works well in win7 and win 10 but I can't find the Cypress fx3 example device 1 driver for linux.

I use the latest release of Ubuntu.

This is the results for: cyusb.conf and lsusb -t:

Where can I find the driver?

All the best,

Ofer.

Hello Ofer,

Please confirm that the FX3 SDK 1.3.4 for Linux is being installed from this link https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit

The Cypress driver can be found in the SDK itself.

Please try programming FX3 with UsbBulkSrcSink example firmware (or any vendor class firmware ) of the SDK and then share the result of the lsusb -t command. This will help us to know whether the driver binds for the vendor class device.

Regards,

Rashi

HI Rashi,

I finished developing. My camera has Its own hardware and firmware (based on AN75779). the UsbBulkSrcSink will not work.

On windows, I don't need to install the SDK to see video or send vendor commands, I only install the Cypress FX3 Example device 1 driver and it works.

I want to do the same for linux.

Hi Ofer,

Please let me know from where did you install the Cypress FX3 Example device 1 driver  on the Windows system

Hi Rashi,

I found it in the driver folder in the windows SDK. But in Linux, I don't see it

Hello,

Please try adding the VID, PID and custom string entry as  Cypress FX3 Example device 1 and 2 in the cyusb.conf file and try using the library.

You can also replace the attached cyusb.conf file in the linux SDK, in which the two entries are added.

Thanks,

Yatheesh

Hello,

I actually got this working without the driver.

Thank you.
