For as many platforms as possible we want to test building and a run of the RC. At least xusb or lsusb -v should be tested. Please use the libusb-1.0.26-rc1.tar.bz2 tarball, and not a git checkout. Use the included configure script, no autogen or bootstrap needed.

Also more application testing is welcome, in particular those who had issues in 1.0.25.

Major platforms

Linux x86_64

  • build: gcc 9.3 (Ubuntu 20.04), gcc 11.2 (Arch Linux)
  • run: xusb, lsusb, dfu-util, libfreenect

Linux arm64 (Raspbian buster)

  • build: gcc 8.3 OK (with and without udev)
  • run: xusb, lsusb, dfu-util

Windows 10 64-bit

  • build: (appveyor does this)
  • run: xusb, libfreenect (crossbuild MinGW)

macOS 12 Intel, macOS 12 ARM64

(mcuee, see following posts)

Other platforms

Windows 32-bit

  • build: (appveyor cross-build on 64-bit)
  • run: dfu-util, lsusb - at least test 32-bit builds on 64-bit OS

macOS 11.6.1 Intel

  • build: Apple clang version 13.0.0 (built both for 11.6 and 10.7)
  • run: lsusb, dfu-util, pyusb

NetBSD, OpenBSD, Haiku

(mcuee, see following posts)

Applications

  • isochronous streaming with libfreenect on XBox - with WinUSB (!)
  • isochronous IN & OUT streaming with custom device (WinUSB, Linux)
  • HackRF HS bulk streaming (WinUSB, Linux)
  • gutenberg printer drivers

Let me try the following. I will see what I can do with more difficult testing involved more transfer type including isochronous transfer.

macOS 12.3 ARM64 (mac Mini M1)

  • build: Apple clang 13.1.6
  • run: xusb, listdev, testlibusb, stress (from libusb project), lsusb, libftdi 1.5 release (find_all, eeprom)

macOS 12.3 x86_64 using Rosetta Translation, not native (mac Mini M1)

  • build:Apple clang 13.1.6
  • run: xusb, listdev, testlibusb, stress (from libusb project), lsusb, libftdi 1.5 release (find_all, eeprom)

Linux x86_64 (Ubuntu 20.04)

  • build: gcc 9.4, known warnings in umockdev
  • run: xusb, listdev, testlibusb, stress and umockdev (from libusb project); lsusb, libftdi 1.5 release (find_all, eeprom)

Linux ARM32 (Raspberry Pi 400 running Raspberry Pi OS Bullseye 32 bit)

  • build: gcc 10.2.1
  • run: xusb, listdev, testlibusb, stress (from libusb project), lsusb, libftdi 1.5 release (find_all, eeprom)

Linux ARM64 (Raspberry Pi 400 running Raspberry Pi OS Bullseye 64 bit)

  • build: gcc 10.2.1
  • run: xusb, listdev, testlibusb, stress (from libusb project), lsusb, libftdi 1.5 release (find_all, eeprom)

Windows VS2019 64 bit (Windows 11 x64 laptop)

  • build:
  • run: xusb, listdev, testlibusb, stress (from libusb project); libftdi 1.5 release (find_all, eeprom)

Windows VS2019 32 bit (Windows 11 x64 laptop)

  • build:
  • run: xusb, listdev, testlibusb, stress (from libusb project); libftdi 1.5 release (find_all, eeprom)

Windows MinGW 64 bit (Windows 11 x64 laptop)

  • build: MSYS2 MinGW-w64 64bit GCC 11.2.0, OK with warnings.
  • run: xusb, listdev, testlibusb, stress (from libusb project)

Windows MinGW 32 bit (Windows 11 x64 laptop)

  • build: MinGW-w64 32 bit GCC 11.2.0, OK with warnings.
  • run: xusb, listdev, testlibusb, stress (from libusb project)

I will carry out the tests on the following platforms as well using Virtualbox VMs under the Windows 11 x64 laptop.

OpenBSD 64 bit (x86_64) -- OpenBSD 7.0 release, VirtualBox VM

  • build: OpenBSD clang 11.1.0
  • run: xusb, listdev, testlibusb, stress (from libusb project)

NetBSD 64 bit (x86_64) -- NetBSD 9.2 release, VirtualBox VM

  • build: NetNSD GCC 7.5.0 OK
  • run: xusb, listdev, testlibusb, stress (from libusb project) --OK

Haiku 64 bit (x86_64) -- r1beta3 release, VirtualBox VM

  • build: build: gcc 8.3.0 Failed -- needs some fixes from Haiku OS side. This does not need to be fixed in libusb-1.0.26 release.
  • run:

Not so sure who will be able to test the following. But we should just proceed with the release if nobody chimed in to test the following platforms.

Solaris 64 bit (x86_64)

  • build:
  • run:

Haiku 64 bit (x86_64) -- probably more recent build (snapshot build)

  • build:
  • run:

Windows on ARM 32 bit

  • build: VS2019: OK
  • run: no machine to test

Windows on ARM 64 bit

  • build: VS2019: OK
  • run: no machine to test

usbutils 007 is from 2013... Didn't we get latest usbutils properly into homebrew recently? Or are you somehow stuck with mikhailai's version?

MSYS2 MinGW gcc 11.2 still have the same warning as in 1.0.25 release. But I think the understanding is that it seems to be a gcc issue. So we do not need to fix this.

Yes, I think the "array subscript" warnings doesn't point to a real problem, but we should ideally fix the code so that the compiler also is convinced it is fine. However the "implicit cast" is new and a real issue (filed in #1100) that can result in wrong error messages at least.

We broke fuzzing somehow. Plan to take a look today to see how we can best fix it.

Do you refer to CIFuzz? The issue in this log is missing pkg-config (pkg.m4 macro) when running bootstrap. I found the log at https://bugs.chromium.org/p/oss-fuzz/issues/list searching for proj:libusb but is there a "button" or dashboard for this?

usbutils 007 is from 2013... Didn't we get latest usbutils properly into homebrew recently? Or are you somehow stuck with mikhailai's version?

Oops I was using the older version from mikhailai. Once I remore the old brew tap and install the latest usbutils, it is now okay. Sorry for the false alarming.

Further tested fxload example under my Mac Mini M1 and it works fine as well.

After that I use Cyusb SDK macOS version example (which use libcyusb on top of libusb) to test isoc transfer and it seems to work fine.

Same thing reported here. It shows "winusbx_submit_bulk_transfer" in the debug log.

Interesting. Let's open a separate ticket for this (or carry on in 759) to not spam the RC testing. We don't expect WinUSB isoch to work correctly. It is indeed using winusbx_submit_bulk_transfer() because we see writing 65536 bytes. Do you have some isoch test in C, without pyusb?

I managed to cross-build latest libfreenect (with latest freeglut) for Windows, using MinGW on Ubuntu - this was a feat in itself. It actually works, isochronous (IN) streaming over WinUSB from an Xbox 360 Kinect camera.

Edit: Confirmed that also isochronous OUT works with a custom device on WinUSB, although reported packet transferred lengths are zero. The data is transferred in both directions, but the log shows:
error [windows_handle_transfer_completion] detected I/O error 87: [87] The parameter is incorrect.
both for OUT and IN transfers. Then in both cases the transfer is submitted again, now with success and the packet actual_length correct for IN but zero for OUT. I wonder if it is just missing actual_length assignment for WinUSB/OUT in winusbx_copy_transfer_data() that is the reason for the zero lengths reported, see #1105. I cannot rule out that the custom firmware is causing the error 87, but on Linux everything seems fine.

That is the problem. All my known-good FW are tested with libusbk Kbench or Cypress FX3 USB SDK host tools, they are not using libusb under Windows. That is why I was using pyusb -- but pyusb may not be correct. I will see if I can try other methods. But I thiink we are good to go for libusb-1.0.26 with regard to isocu transfer support.

One more test with HID device under Windows.
FW for PIC1887J50 and host code here.
https://github.com/mcuee/picusb/tree/master/lvr_genhid_mod

It seems to work fine. The host code sends one extra byte to see if the device will respond or not.

Your test results seem to be in line with some of my test results, like the transfer size report as 0 and Error 87.

As requested by @tormodvolden I've run some tests with HackRF.

We're pretty sensitive to any transfer throughput issues since we stream at 40MB/s with little latency margin, and we do it with bulk transfers.

I tested on Linux, and on Windows with the WinUSB backend. I ran hackrf_transfer in transmit and receive mode, hackrf_sweep, and a test program we've been using called hackrf_loop which repeatedly starts & stops streaming.

Everything seems to work fine on both Linux and Windows with 1.0.26-rc1 and I don't see any changes to our streaming performance there - Windows has latency problems at full sample rate, but that's unchanged across libusb releases.

I had previously been running 1.0.24, so I also tested 1.0.25 to see if we had been affected by bugs in that release.

On 1.0.25, hackrf_transfer on Windows segfaults just before normal exit, after printing:

libusb: debug [libusb_free_transfer] transfer 000001e6f888a5b8

That problem is fixed by 1.0.26-rc1.
