Hi ALL,
I am using CY7C68013A on Ubuntu 16.04 with a x64 computer. The USB device works fine in Windows and also can be recognized by Linux with cyusb_linux application.
The firmware is the same as that in windows and I just want to develop host application on Linux.
I installed the cyusb_linux step by step following the user guide and readme.
But, when I try to select the device in the device list on the GUI, the application crashed and pop the error in the console:
cyusb_linux: symbol lookup error: cyusb_linux: undefined symbol: libusb_get_ss_endpoint_companion_descriptor
I tried to figure out the reason, but without luck.
What may cause this error?
Any clue or help will be appreciated.
Thanks,
Zheng

Hello Zheng,
We checked the same on Ubuntu 16.04 (x64 bit) system and found the application to be working fine. Please ensure the path /usr/local/lib includes all the shared libraries before running the application. The symbol may not be defined in the given library path, you can use the 'nm' command and check if any undefined symbol is present.
Best Regards,
Sananya
