Recently I need to develop USB driver under QNX4.25.
I didn’t have license for QNX4.25 yet, and I heard that QNX4.25 RTOS does not include IDE inside it.
There’s no IDE for QNX 4 like the one in QNX 6. You do need the USB DDK. You should contact your representative about a development license and to obtain the USB DDK.
