How to fix 'LIBUSB_ERROR_NOT_FOUND' error when calling libusb_bulk_transfer

问题 I'm creating a program that reads in input from a midi controller using libusb. How do I properly call libusb_bulk_transfer? Currently I'm receiving the error "LIBUSB_ERROR_NOT_FOUND" every time, and the data that I receive is "P". I've swapped out the function 'libusb_bulk_transfer' with 'libusb_interrupt_transfer' but I still receive the same error: LIBUSB_ERROR_NOT_FOUND Below are the libraries that I currently have included #include <stdlib.h> #include <stdio.h> #include <libusb-1.0

How to install libusb?

问题 I am having hard time installing libusb. I went across some YouTube videos, and they were talking about "INSTALLING" libusb. I went across another tutorial and they are saying we need to build it "manually". However, I downloaded libusb from http://sourceforge.net/projects/libusb-win32/files/. In my download, there is no software to install (according to video, it is libusb_win32.exe). My OS is Windows 7 Ultimate 32 bit. The PC is a Dell Inspiron 4030 (I need to install this in my desktop PC

问题 I'm a newbie in libusb c programming. Should I know the difference between libusb.h and usb.h? I have installed both of them in Ubuntu(xenial) with package libusb-1.0-0-dev and libusb-dev. Which one is better? Are they from the same origin libusb.info? Thanks, 回答1: The libusb library has onetime switched from version 0.1 to version 1.0, breaking compatibility. usb.h - is a header for libusb 0.1, the older one. libusb.h - is a header for libusb 1.0, the newer one. Correspondingly, libusb-dev

Device Not Available on PyUSB

问题 Playing around with PyUSB a bit to see if it offers some insight as to why a WebUSB library I'm using isn't finding my device. I installed libusb1 on the Mac via Homebrew with brew install libusb . Ran lsusb -vv to get device details. Also set a couple of environment variables for PyUSB: export PYUSB_LOG_FILENAME=pysubdebug.log and export PYUSB_DEBUG=debug import usb VENDOR_ID = 0x0483 PRODUCT_ID = 0x5740 DATA_SIZE = 1 device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID) >>>

问题 I have made a program using libusb. I doubt if the output is correct as all the entries show the same vendor and product id. Following is the code: #include <stdio.h> #include <stdlib.h> #include <libusb-1.0/libusb.h> void print_devices(libusb_device *dev) { struct libusb_device_descriptor desc; struct libusb_config_descriptor *config; const struct libusb_interface *inter; const struct libusb_interface_descriptor *interdesc; const struct libusb_endpoint_descriptor *endpointdesc; int ret; int

问题 I've successfully installed pyocd and libusb using powershell core and python 3.8 on windows 10, but when I use python -m pyocd list command, it throws this error: PS C:\Users\mahya> python -m pyocd list 0003915:WARNING:common:STLink and CMSIS-DAPv2 probes are not supported because no libusb library was found. No available debug probes are connected this is the list of installed python libraries: 回答1: You should copy the libusb.dll (libusb dynamic link library) to the path of python
