Hello all,following my humble beginings with USB programming on Linux, I have a question. When I started I thought I would have to do kernel programming (modules and the like) to access the hardware. Then I discovered direct IOCTL calls and later the even more simple libusb.
Now my question is, when do you need to write kernel modules for USB access ? Never as it's all handled by user libraries ? Only if you want very high performance ? In case of special needs ?
