First, try disabling Gatekeeper it's the option that stops you from running non-signed apps. If that doesn't work, this may be worth a try, but I don't know if it'll do anything. Some versions of OS X apparently have a switch that allows loading modified drivers normally you can't.
The command is:. Listen now.
If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Version: 1. On Windows, any generic interface that you want to access with this library must use WinUSB as its driver, so you will need to provide a driver package or use some other mechanism to make sure WinUSB is installed.
There is no support for switching device configurations or switching between alternate settings of an interface. There is no support for accessing a generic interface that is included in an interface association and is not the first interface in the association.

Because these APIs have different capabilities and behavior, you should not assume your program will work on a platform on which it has not been tested. This library has a lot in common with libusb 1. These instructions assume you are building a bit binary. Then run this command to install the required packages:. Download the source code of this library and navigate to the top-level directory using cd.
Using USB devices with your Mac
Then run these commands to build the library and install it:. We currently do not provide any build files for Visual Studio. You can use CMake to generate Visual Studio build files, and the library and its examples will probably compile, but we have not tested the resulting library. First, you will need to make sure that you have a suitable compiler installed, such as gcc.
You can run gcc -v in a shell to make sure it is available. You will also need to install CMake and libudev. On Ubuntu, Raspbian, and other Debian-based distributions, the command to do this is:. First, install Homebrew , a package manager for macOS. Then use Homebrew to install CMake by running the following command in a Terminal:. Then run these commands in a Terminal to build the library and install it:.
The first step to incorporating libusbp into another project is to add the libusbp header folder to your project's include search path. The header folder is the folder that contains libusbp. On systems with pkg-config , assuming libusbp has been installed properly, you can run the following command to get the include directory:.
The output of that command is formatted so that it can be directly added to the command-line arguments for most compilers. Next, you should include the appropriate libusbp header in your source code by adding an include directive at the top of one of your source files. After making the changes above, you should be able compile your project successfully. If the compiler says that the libusbp header file cannot be found, make sure you have specified the include path correctly as described above.

If you add a call to any of the libusbp functions and rebuild, you will probably get an undefined reference error from the linker. To fix this, you need to add libusbp's linker settings to your project. Distinguish identical devices Sometimes you have to plug two identical devices and you cannot distinguish them. Either you have to activate more criteria in the filter, like the "Serial No.
If they're really identical even the serial number , there's not that much you can do.
There is a technique that might work, but it's so rare and convoluted that it's not part of the FAQ. Start a new topic describing your problem. There are some "hacks" around but nothing tested certain. Something like a USB mouse or keyboard or joystick typically works. The instructions are in the article " USB 3. Win7 : you need to install the " Intel USB 3. Apr , 7: Troubleshooting Shutdown your guest from within your guest, normal shutdown.
Shutdown your host. Reboot your host. Relaunch your guest. This has helped at times, to have a clean start of both host and guest. If the device shows up in your host and is not captured by the filter, either the filter is incorrect, or there might be a problem with your filter installation.
For example you may have a blank filter, or a narrowly defined filter too many conditionals. If the device shows up, but as "Unavailable", eject it from your host if you can , but leave it plugged in. It should show up as available. On Linux hosts, check the output of " lsusb ".
On Mac hosts, check the "System Information". And of course you have to be using the 5.

If on a Linux host, are you a member of the 'vboxusers' group? Jun , 8: Asking for help If you've tried everything so far, and you had no luck, maybe it's time to open a new thread. Please read the Minimum information needed for assistance. Use the complete version numbers including the build numbers to identify software. Now, with the USB device plugged in and the VM not running , post the output of the following commands.
Note that the 1st command applies to Windows hosts only , and the 2nd to Linux hosts only. After you've logged in, plug the USB device. Wait idling for a minute or two.
Unplug the USB device. Shutdown the VM not paused or saved.
