Thanks for the response.
I followed the procedure :
sudo apt-get install openjdk-11-j* openjfx
And got :
openjdk version “11.0.11” 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.18.04)
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.18.04, mixed mode)
18:41:25.838 FINE (unified.bootloader32bit.UBootFXML32bitController$1 changed) - USB Protocol Selected
18:41:31.821 SEVERE (unified.bootloader32bit.UBootFXML32bitController configureUsbSettings) - Failed to Configure USB Settings. org.hid4java.HidException: Hidapi did not initialise: Unable to load library ‘hidapi’: Native library (linux-aarch64/libhidapi.so) not found in resource path (UnifiedHost-1.17.0.jar)
Can you suggest the right package for : libhidapi.so
since i already have :
$ ls libhidapi*
libhidapi-hidraw.a libhidapi-hidraw.so.0 libhidapi-libusb.a libhidapi-libusb.so.0
libhidapi-hidraw.so libhidapi-hidraw.so.0.0.0 libhidapi-libusb.so libhidapi-libusb.so.0.0.0
