Beside, I can access CDC device from any terminal program. I’ve just had a minor breakthrough!

In linux, program worked as expected. Thanks for the hint on IOKit, I’ll definitely look into it, but do want to avoid opening a can of worms that’s going to waste another week of my time. I don’t know why. A couple of questions come to mind. Also, when the application exists, my terminal window gets screwed up. I’m playing around with the following sample I found on http: I take the code from https: Yes I install the driver but problem still exist.

It simply sends “on” with nothing else. It turns out that libusb only works with the winUSB-Drivers. Stack Overflow works best with JavaScript enabled.

[SOLVED] Serial communication with USB CDC device (libusb/termios)

The composite device is a USB 2. I’m trying to manipulate it to send the string “on” to my device: Forums Posts Latest Posts. I use Visual Studio’s compiler. Do you see any characters ccc out?

Now, option one, using libusb, is failing miserably, as Mac is stingy, and does not libusbb to let go of the USB CDC resource, so I can claim the interface and do stuff with it. I think I’ll post a separate StackOverflow question on that shortly. Easiest for me was to use the zadig installer see link in the link in the comments above to remove usbser driver and exchange it by the winusb one for this one device.

Libisb to send “on” to the device, and my little green LED went lighting up like a Christmas tree. Is there an alternative to libusb library intended for USB communication?

It sounds way easier to just use termios to do communication, libusn way, I suppose I can keep a tiny bit of platform independence between Linux and OS X. Thank you for your reply.
