Question:
How do you make a device with a custom vendor identification (VID) number / product identification (PID) number visible on the cyusb_linux GUI?

Answer:
By default, the cyusb_linux GUI (Control Center equivalent for Linux) only shows devices with a Cypress® VID (0x04B4) and PIDs contained in the /etc/cyusb.conf file.

If you are using a Cypress VID (0x04B4) and any PID that is not present in the /etc/cyusb.conf file, you will have to add the VID (0x04B4) and the PID to the end of the /etc/cyusb.conf file. You will need root permissions to do this. If the cyusb_linux GUI is already open, close it and start it again. The device will now appear in the cyusb_linux GUI.

If you are using a non-Cypress VID, follow the steps below. For this example, the VID is 0x04FF and the PID is 0xFF.

1.Add the VID and PID in /etc/cyusb.conf as shown in Figure 1. You will need root permissions.

2.For a non-Cypress VID, you will need to make changes in the /etc/udev/rules.d/88-cyusb.rules file as well. You will need root permissions. Copy lines four and five of the 88-cyusb.rules file and paste it back into the file with ATTR{idVendor}==”04b4” changed to ATTR{idVendor}==””, as shown in Figure 2.

3.Close and restart the cyusb_linux GUI. The device with a custom VID/PID will now appear in the GUI as shown in Figure 3.
