    cyusb_linux: undefined symbol: libusb_get_ss_endpoint_companion_descriptor

      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
