hidapi Cannot list all devices (Ubuntu 15.04, ASUS)

Hello.

I have downloaded and installed all hidapi libraries, my computer is an Asus laptop with Ubuntu 15.04. When I run the hidtest-hidraw and hidtest-libusb examples (also with root user), only the mouse is listed. I connect an Arduino UNO board, a pendrive, and the program does not recognize them at all.

How can I solve this problem? I would like to be able to develop C or C++ programs that can communicate with my Arduino or with other USB devices.

Thanks.

Permissions?

Also, many devices are blacklisted from hidraw.

BTW, arduino and USB thumb drives are not HID devices and won't show up in hidapi.

Hi!

Thanks for your reply :-) .

As you mentioned, I have discovered that Arduino boards are not HID devices, neither external storage disks and pendrives. I have discovered it later (I am kind newbie using HID API).

Regards,

Luisda.

Arduino boards can act as HID device. See RawHID and (on the dev tree) the feature report keyboard example. https://github.com/NicoHood/HID

I am currently developing an ambilight via a keyboard feature request. Also see this: https://github.com/arduino/Arduino/pull/4105

Are POS printers HID devices also?
