* To compile on linux ensure you have libusb-1.0 installed
|
||||
* e.g. apt install libusb-1.0-0-dev
|
||||
* Also works on MinGW with both static build and DLLs from MSVC builds
|
||||
* gcc -o testlibusb testlibusb.c -lusb-1.0
|
||||
*
|
||||
* Test suite program based of libusb-0.1-compat testlibusb
