libusbp's Issues

Does not build with MSYS2 mingw64 on Windows 11

I followed the instructions to the letter with a brand new install of MSYS2.

However, at the point of running the CMAKE command, all I get is this:

MINGW64 ~/libusbp/build
$ MSYS2_ARG_CONV_EXCL=- cmake .. -G"MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=$MINGW_PREFIX
CMake Error: CMake was unable to find a build program corresponding to "MSYS Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_AR was not found, please set to archive program.
-- Configuring incomplete, errors occurred!

I'm guessing that either some assumptions are made about things that have already been installed, or I'm mis-interpreting something.

I ran this as advised in a similar issue:

$ echo $MSYSTEM
which cmake
which gcc
MINGW64
/mingw64/bin/cmake
/mingw64/bin/gcc

Please advise.

(I had no problems with the macOS or Linux builds, btw)

Thoughts on compatibility with libusb?

I was wondering what your thoughts were on some day offering an interface that is compatible with libusb, so that for some applications libusbp could be offered as a drop-in-replacement.

I am personally working with libftdi.

What was your experience with contributing changes to libusb that you made your own library?

Wasm Port

Please port to wasm so we can get USB support in browsers.

Here is a tool to do it:

FTDI port number cannot be retrieved on Windows

I'm plugging an FTDI based device, under Windows 10. When I plug it and use windows API SetupDiGetClassDevs/SetupDiEnumDeviceInfo/SetupDiGetDeviceRegistryProperty, I find device named FTDIBUS\COMPORT&VID_0403&PID_6001 with port name "COM8".

Now, when I use libusbp/lsport, the device is found (0403:6001 AR0JFBPE) but its port name cannot be identified, all call to try_print_port_name returns false. I even changed the loop parameter to test the 256 possible interface_number with no success.

port_name : Error

port_name example throws error 'The PortName key was not found' for a USB printer Vendor Id: 0x0A5F, Product Id: 0x0081, interface_number = 0, composite = false.
But the other examples like 'lsport' and 'lsusb' where successfully detect the device.

undefined reference to `libusbp_error_free'

I installed the library as explained in the readme file and had no issues. Used it without problems. Recenntly I tried to build my ROS project (ROS kinetic/Ubuntu 16.04) which includes the libusbp library and I'm getting a compilation error.

CMakeFiles/gimbal_interface_node.dir/src/gimbal_interface_node.cpp.o: In function libusbp::pointer_free(libusbp_error*)': gimbal_interface_node.cpp:(.text._ZN7libusbp12pointer_freeEP13libusbp_error[_ZN7libusbp12pointer_freeEP13libusbp_error]+0x14): undefined reference to libusbp_error_free'

CMakeFiles/gimbal_interface_node.dir/src/gimbal_interface_node.cpp.o: In function libusbp::pointer_free(libusbp_device*)': gimbal_interface_node.cpp:(.text._ZN7libusbp12pointer_freeEP14libusbp_device[_ZN7libusbp12pointer_freeEP14libusbp_device]+0x14): undefined reference to libusbp_device_free'

Then there are a couple more undefined reference to other functions.

Need to access device's friendly name

Under Windows, I need to access device's friendly name (SetupDiGetDeviceRegistryProperty with property SPDRP_FRIENDLYNAME).

This information is not part of libusbp::device. May it be added to the API? It's probably only available under Windows, I did not check. Would that be an acceptable pull request?

Else, can one retrieve the internal device handle from libusbp::device and later call SetupDiGetDeviceRegistryProperty?

cmake not working on win10 under msys2

The command
MSYS2_ARG_CONV_EXCL=- cmake .. -G"MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=$MINGW_PREFIX
issues an error saying MSYS generator is not available.

I built it using
MSYS2_ARG_CONV_EXCL=- cmake .. -G"Unix Makefiles" -DCMAKE_INSTALL_PREFIX=$MINGW_PREFIX
but there was no definition of WINDOWS, APPLE nor LINUX for CMakeLists.txt. As a workaround I edited it to include only the windows relative files.

make install DESTDIR=/
failed to write the output libraries on windows, I think it needs the destdir to be absolute rather than relative.

macOS Port is not found for FTDI devices

Hi,

On macOS, because of the interface_number += 1, the port is not found for FTDI devices. Here is how it's reported with ioreg:

Project can't be included as a sub-project of another CMake project

Attempting to use CMakes fetchcontent() facility or simply including this project as a sub-project (or dependency) of another CMake project fails due to incorrect use of CMAKE_SOURCE_DIR in when setting up the include paths in src/CMakeLists.txt

The use of CMAKE_SOURCE_DIR should be replaced with CMAKE_PROJECT_SOURCE_DIR.
Additionally the use of CMAKE_CURRENT_*_DIR variables should probably be changed to use the CMAKE_PROJECT_*_DIR versions.

There maybe other similar changes required.
