Hi

I try to update an IOIO-OTG firmware but the ioiodude throw the error:

$ sudo ./ioiodude --port=/dev/IOIO0 versions
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't obtain updateLastError method for class com.sun.jna.Native
    at com.sun.jna.Native.initIDs(Native Method)

The error occured with java-7-openjdk-amd64 as with java-6-openjdk-amd64. Running on an "Ubuntu 14.04.3 LTS" (trusty).

This is likely because of the sudo. Fix your udev rules according to the wiki and you shouldn't need it. Otherwise, open a discussion on the ioio-users list.
