Why do you think this is a libusb bug and not the application "analysis-dbg.exe"?

Are you the author of the application? If yes please post the relevant codes.

#include <libusb-1.0/libusb.h>

int main(int argc, char* argv[]){
  libusb_context* libusbContext = nullptr;
  if(libusb_init(&libusbContext) != LIBUSB_SUCCESS)
    return -1;

    libusb_close(handle);
  }
  libusb_free_device_list(devList, 1);
  libusb_exit(libusbContext);
  return 0;
}

This is minimal compilable sample to reproduce the error. Compilation was done with 'gcc.exe -g main.cpp -lusb-1.0 -omain' command. I am using gcc-9.3.0 and libusb-1.0.24. There was no error with libusb-1.0.23. If comment out line 'libusb_claim_interface(handle, 0);' the error disappears. As you can see from debugger output the error occurs in a separate thread created by libusb_init(...). It does not looks like a bug in my program. libusb-error

mcuee commented 3 years ago

Did you install the supported driver? You have to do that in order to claim an interface. https://github.com/libusb/libusb/wiki/Windows#Driver_Installation

And please post the debug log by setting env variable LIBUSB_DEBUG=4 and then run your application.

kulkin-fish commented 3 years ago

Driver libusbK is installed. As I mentioned above there is no problem with libusb-1.0.23. libusb-error-2.txt libusb-error-2

mcuee commented 3 years ago

Thanks for the updates. Please help to post the USB Descriptors. That may play a part.

You can use USBView utility or other utilities. Microsoft USBView: https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/usbview https://ftdichip.com/utilities/ (small download, FTDI version)

mcuee commented 3 years ago

The other possibility, please switch to WinUSB driver and delete libusbk.dll from the system to see if this issue is applicable only to libusbk or it also applies to WinUSB. Thanks.

mcuee commented 3 years ago

BTW, which MinGW compiler you are using?

Do you use the prebuilt binaries, in that case, please take note that we do not support MinGW.org 32bit compilers. You have to use MinGW-w64 compilers (32bit and 64bit, you are recommended to use MSY2 distribution), and you may have to build the binary from source due to compatibilities between different compiler versions.

Please rebuild the libusb library files again using your compiler version and then try again. Thanks.

photron commented 3 years ago

This looks like a duplicate of issue #844 to me, which has been fixed in commit b51c743e4210756a98f4f60c69a34745e4b27a55. But this is not released yet.

Please test with current git master instead of release 1.0.24.

mcuee commented 3 years ago

@kulkin-fish Please help to test git master to see if the issue goes away. Thanks.

kulkin-fish commented 3 years ago

Indeed master from git has no such bug. But has another one :) Looks like some deadlock. image

mcuee commented 3 years ago

Thanks for the updates. Did this issue happen with WinUSB driver?

kulkin-fish commented 3 years ago

photron commented 3 years ago

I tested your minimal example (but changed the VID to match my device) and cannot reproduce the deadlock. But I'm using WinUSB instead of libusbK.

According to your backtrace thread 1 is waiting for the IOCP thread (thread 5 in the backtrace) in the Windows backend to exit. But thread 5 is trying to lock a dev_handle and is blocked there. The question is now who is holding the dev_handle lock, or who has not unlocked the dev_handle lock.

Can you make your example more minimal, or does it have to open the device and claim the interface for the deadlock to occur?

Does the deadlock occur every time?

Could you provide a debug log again?

kulkin-fish commented 3 years ago

Situation is stable. I can reproduce it every time running application. If comment 'libusb_claim_interface' the problem is not occured. Log is: image

One more thing. With LIBUSB_DEBUG=4 my DrMinGW popuped with text: image

I made some modifications to my source:

#include <libusb-1.0/libusb.h>

int main(int argc, char* argv[]){
  libusb_context* libusbContext = nullptr;
  if(libusb_init(&libusbContext) != LIBUSB_SUCCESS)
    return -1;

  libusb_device** devList = nullptr;
  const int devCount = libusb_get_device_list(libusbContext, &devList);
  if(devCount <= 0){
    libusb_exit(libusbContext);
    return 0;
  }

  for(int i = 0; i < devCount; ++i){
    libusb_device_descriptor desc;
    libusb_get_device_descriptor(devList[i], &desc);

    if(desc.idVendor != 0x0525)
      continue;

    libusb_device_handle* handle = nullptr;
    if(libusb_open(devList[i], &handle) != LIBUSB_SUCCESS)
      continue;

    if(argc > 1)
      libusb_claim_interface(handle, 0);
    libusb_close(handle);
  }
  libusb_free_device_list(devList, 1);
  libusb_exit(libusbContext);
  return 0;
}

Running with any parameter in command line causes libusb_claim_interface to be called. Without any command line parameter libusb_claim_interface not called. Running without parameters is OK every time (e.g. without caliming interface). Running with any parameter is deadlocked everytime.

kulkin-fish commented 3 years ago

Even without LIBUSB_DEBUG i've got the message: image

mcuee commented 3 years ago

@kulkin-fish Please switch from libusbk driver to WinUSB driver using Zadig, and see if the issue is still there or not.

Unless you hit into WinUSB driver limitations, you should use WinUSB driver and not libusbk.

Confirmed. Switch to WinUSB driver eliminates the problem. Does that mean libusb has no bugs with libusbK?

mcuee commented 3 years ago

Thanks for the updates. So looks like there is an issue with libusbk backend.

Please help to post the debug log with WinUSB as well for comparison. Thanks.

mcuee commented 3 years ago

I can reproduce your issue under Windows 10 and MSYS2 MinGW-w64. So I can confirm there is an issue with libusbk.sys backend.

I have a USB device with firmware compatible with WinUSB device. https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/automatic-installation-of-winusb

When I switch the driver from WinUSB to libusbk using Zadig. And I run your program (just change the VID to 0x04d8 as it is from Microchip), it crashes just as what you reported.

When I switch the driver back to WinUSB using Windows Device Manager, it will be okay.

mcuee commented 3 years ago

@dickens Please take a look when you got the time. Thanks.

mcuee commented 3 years ago

I am not so sure if it is the code or not, but this happens under libusb-1.0.24 but not happen under 1.0.23.

mcuee commented 3 years ago

@kulkin-fish Please help to try out 1.0.23 as well and this may help to narrow down the potential issue. Thanks. If 1.0.23 works but 1.0.24 does not, then we know it is related to the changes in between.

mcuee commented 3 years ago

Initially I was worried it is related to https://github.com/libusb/libusb/commit/b51c743e4210756a98f4f60c69a34745e4b27a55 because of #863 (fixed in https://github.com/libusb/libusb/commit/a108bb8e185cc5c41b296d35dfa83e5e5b13b2c0) but apparently not since 1.0.24 release already got the issue with libusbk.

mcuee commented 3 years ago

This may be related to #844 as well which is fixed by commit https://github.com/libusb/libusb/commit/b51c743e4210756a98f4f60c69a34745e4b27a55

Windows: Filter out non-libusb I/O completions The I/O completion port thread gets notified of every I/O operation that completes for a given HANDLE, but not all I/O operations originate from within libusb. For example, libusbK performs a number of I/O control calls during initialization and specific device operations, such as setting an interface alternate setting. These non-libusb operations need to be ignored as the OVERLAPPED associated with such operations is not tied to a libusb_transfer structure.

Resolve this situation by using the libusb device handle as the I/O completion port's unique key and keeping a list of active transfers for each device handle. When the I/O competion port thread is notified of an I/O completion, it will first match the OVERLAPPED to an outstanding transfer before acting on it.

Access violation in libusb v1.0.24 when using libusbK driver

mcuee commented 3 years ago

I did some tests and it seems to me libusb git head already fixed the issue. Initially I was not testing correctly because I was still using the dll from MSYS2's libusb-1.0.dll which was 1.0.24. Now I just use libusb-1.0.dll built from the latest git and it seems me the issue is no longer there.

Edit: sorry my tests are not conclusive. I got mixed results. Looks like the issue is still there in the latest git. With 1.0.24, 100% it will fail. With latest git, sometime it passed in a row and that was why I considered it passed. But then I found that sometimes it failed in a row.

@kulkin-fish Please test the latest git to see if you get the same segfault or not. I know you are already testing git version 1.0.24.11615 but please try again for the latest git.

mcuee commented 3 years ago

On the other hand, xusb example runs fine with 1.0.24 and latest git with libusbk driver. So maybe the test code has some issues as well.

@kulkin-fish Maybe you want to take some references from the xusb example and other official libusb examples as well.

tormodvolden commented 3 years ago

Does it crash if you release all claimed interfaces before libusb_exit() ?

mcuee commented 3 years ago

BTW, I tested with an HID device and the test code does not crash. Device using WinUSB driver also does not crash. So it is very specific to libusbk driver (through libusbK.dll).

mcuee commented 3 years ago

It seems to me libusbk backend may have an issue. I changed to the following code and it still crashes with the latest git head. I suspect that commit https://github.com/libusb/libusb/commit/b51c743e4210756a98f4f60c69a34745e4b27a55 does not catch all the issues related to libusbk.

  libusb_context* libusbContext = nullptr;
  if(libusb_init(&libusbContext) != LIBUSB_SUCCESS)
    return -1;

  libusb_device** devList = nullptr;
  const int devCount = libusb_get_device_list(libusbContext, &devList);
  if(devCount <= 0){
    libusb_exit(libusbContext);
    return 0;
  }

  for(int i = 0; i < devCount; ++i){
    libusb_device_descriptor desc;
    libusb_get_device_descriptor(devList[i], &desc);

    if(desc.idVendor != 0x0403)
      continue;

    libusb_device_handle* handle = nullptr;
    if(libusb_open(devList[i], &handle) != LIBUSB_SUCCESS)
      continue;

Windows: Use I/O completion ports for transfers …

Windows: Use I/O completion ports for transfers
As a first step in removing the Windows poll() emulation, switch the
transfers to use an I/O completion port. A dedicated per-context thread
will wait on the I/O completion port and report transfer completions
using usbi_signal_transfer_completion(). This enables the complete
removal of the handle_events() function for the Windows backend and
removes the notion of one "file descriptor" per transfer.

However, if I go back to OP's test program, I will still be able to recreate the crash under MSYS2 MinGW with latest git. It is not consistent, sometime it will hang, sometimes it will pass, sometimes it will segfault. If not using MSYS2 MinGW prompt but rather under Windows terminal, the program will hang for a short time and then exit.

#include <libusb-1.0/libusb.h>

int main(int argc, char* argv[]){
  libusb_context* libusbContext = nullptr;
  if(libusb_init(&libusbContext) != LIBUSB_SUCCESS)
    return -1;

  libusb_device** devList = nullptr;
  const int devCount = libusb_get_device_list(libusbContext, &devList);
  if(devCount <= 0){
    libusb_exit(libusbContext);
    return 0;
  }

  for(int i = 0; i < devCount; ++i){
    libusb_device_descriptor desc;
    libusb_get_device_descriptor(devList[i], &desc);

    if(desc.idVendor != 0x04d8)
      continue;

    libusb_device_handle* handle = nullptr;
    if(libusb_open(devList[i], &handle) != LIBUSB_SUCCESS)
      continue;

    if(argc > 1)
      libusb_claim_interface(handle, 0);
    libusb_close(handle);
  }
  libusb_free_device_list(devList, 1);
  libusb_exit(libusbContext);
  return 0;
}
