I tried downloading the code for USBM from here as a zip file.
When I unzip it, using 7-zip is complains about duplicate file. Is this because there are symlinks in source tree?
Also is Eclipse required for building the USBDM code?
The directory name problem is caused by changing the name of the folder on Windows which is not case sensitive and then uploading to GIT which is. The correct folder is UsbdmJniWrapper_DLL.
Eclipse is needed to build the Eclipse plugins. There are make files for the C code.
