libusb-devel Mailing List for libusb

We are happy to announce the final release of libusb 1.0.28.

This is a rather small maintenance release with a few bug and build
fixes in addition to one new API function.

ChangeLog with most important changes since previous release 1.0.27:
* New libusb_get_ssplus_usb_device_capability_descriptor API
  for query of SuperSpeed+ Capability Descriptors
* API support for reporting USB 3.2 Gen2x2 speeds
* macOS: Fix Zero-Length Packet for multiple packets per frame
* Windows: Base HID device descriptor on OS-cached values
* Build fixes for Haiku and SunOS
* Many code correctness fixes

The source code tarball can be downloaded here:
https://github.com/libusb/libusb/releases/download/v1.0.28/libusb-1.0.28.tar.bz2

An archive of Windows binaries can be downloaded here:
https://github.com/libusb/libusb/releases/download/v1.0.28/libusb-1.0.28.7z

Note that the release tarball includes a configure script so unlike a
git checkout it is not necessary to bootstrap with autoconf.

The 1.0.28 release was made possible by the contributions from all
patch submitters (see below git shortlog with 64 commits from 12
contributors, of which 6 new) plus everyone who contributed with issue
reporting, discussions and testing.

On behalf of the libusb development community,
Tormod

https://github.com/libusb/libusb/issues/1615 to track what has been
tested.

Download:
https://github.com/libusb/libusb/releases/download/v1.0.28-rc1/libusb-1.0.28-rc1.tar.bz2

Note that the RC tarball includes a configure script so unlike a git
checkout it is not necessary to bootstrap it with autoconf. The
"check" target will run a number of tests:
  tar jxvf libusb-1.0.28-rc1.tar.bz2
  cd libusb-1.0.28-rc1
  ./configure --enable-tests-build --enable-examples-build
  make check

The current ChangeLog:
* New libusb_get_ssplus_usb_device_capability_descriptor API
  for query of SuperSpeed+ Capability Descriptors
* API support for reporting USB 3.2 Gen2x2 speeds
* macOS: Fix Zero-Length Packet for multiple packets per frame
* Windows: Base HID device descriptor on OS-cached values
* Build fixes for Haiku and SunOS
* Many code correctness fixes

Since 1.0.27, 61 commits by 12 contributors (6 new!)

This is a rather small maintenance release with a few bug and build
fixes in addition to the new API function.

Hi everyone,

Are there currently any plans on getting pull request #1521 merged?

As a reminder, this fixes a Windows corner case where the same bus number can
get assigned to multiple different root hubs. This is quite an annoying bug to 
work around, and I think it's quite important to fix it.

Of course, I'd be happy to address any concerns or requests regarding the pull
request itself.

Link to the pull request: https://github.com/libusb/libusb/pull/1521

Best Regards,

Thank you @David Grayson<mailto:dav...@gm...>!!

You are correct, My ubuntu system itself is somewhat broken as update command is also not working.

sudo apt-get  update

Hi David,

I tried this as well but getting similar error

sudo apt-get install libusb-1.0-0-dev
apt-get: error while loading shared libraries: libcgmanager.so.0: cannot open shared object file: No such file or directory

The question still boil out to , if ubuntu version is 22.04, what are the ways to install libcgmanager.

Instead of downloading libusb's source just install it with apt-get:

Did you search for this at all before asking?  You need to install the libcgmanager0 package:

I don't think you read my message at all.  The APT package is called "libcgmanager0" with a trailing 0.

Hi David,

I tried this as well but getting similar error

Hi,

I want to compile libuvc application----  https://libuvc.github.io/libuvc/

For that libusb<https://libusb.info/> 1.0+ is needed. I downloaded libusb-1.0.27.tar.bz2<https://github.com/libusb/libusb/releases/download/v1.0.27/libusb-1.0.27.tar.bz2> from the releases.

Following below steps for installing it.

tar jxvf libusb-1.0.27-rc2.tar.bz2
cd libusb-1.0.27-rc2
./configure --enable-tests-build --enable-examples-build
make check

getting below error while installing it---

error while loading shared libraries: libcgmanager.so.0: cannot open shared object file: No such file or directory

sudo apt-get install libcgmanager
apt-get: error while loading shared libraries: libcgmanager.so.0: cannot open shared object file: No such file or directory

Basically, I not able to install this library.

I am working on ubuntu version --- Ubuntu 22.04.4 LTS

Swati

Our device is the only one demanding on the USB bus, so nothing else should be using more than 100 MB/s.
The issue occurred on various computers with different USB ports and controllers. However, I can check if there’s another USB controller on the computer that’s currently failing. If it works on that one, I could assume the issue is with the controller. Do you know if there’s a way, either through libusb or Windows, to access the available resources of the USB bus? This would allow me to see if there’s indeed an inability to lock our 300 MB/s.

________________________________


Well, mostly.  You're asking for 300 MB/s.  The total bus capacity after encoding is about 500 MB/s, but only 80% of that bandwidth is allowed to be allocated to reservations for interrupt and isochronous pipes.  Mice and keyboards also have reservations, although USB 2 traffic travels on different wires from USB 3 traffic.


It could just be a host controller failure.  Do these errors happen on the same types of computers?

Hello,
We are indeed using an isochronous endpoint in our alternate setting. We are working on a USB 5 Gb/s connection, and the endpoint is configured as follows:

  *   Maximum packet size: 1024
  *   Burst size: 12
  *   Number of iso-packets: 3
  *   Service interval: 1 uFrame

Theoretical throughput is then around 2.4 Gb/s, so we should be within the allowed bandwidth. Additionally, no other USB devices (besides a mouse and a keyboard) are connected.
The issue is that if it were asking for more than the possible bandwidth, this should happen systematically and be reproducible. Here, it is basically that one day we will just plug in a new device, and the issue will be present. Even previous devices that were correctly accessed are now presenting the issue.

What are the endpoints are in your alternate settings?  Usually, this error means that your alternate setting contains an isochronous or interrupt endpoint, and the reservation you asked for exceeded the reservation limit for the bus.  For example, if you try to start two video cameras on a USB 2 bus that's already running USB audio, that will exceed the limit.

Dear libusb community,
I am reaching out for help regarding an unexpected error we have encountered using libusb on Windows.
First of all, I believe this issue is probably more related to Windows and WinUSB itself, and I also intend to seek help from their side. However, I am trying my luck here to see if this is a known issue and if there might be some workaround.
Regarding the issue: “Randomly”, with our custom USB device, libusb reports a systematic failure when attempting to set the device to a specific alternate setting. When setting the log levels to debug, the following issue is reported: “libusb: error [winusbx_set_interface_altsetting] SetCurrentAlternateSetting failed: Insufficient system resources exist to complete the requested service.” I have looked into existing topics regarding this issue but found none answered, at least related to USB. Usually, the issue appears to be more observable on computers that are not often turned off, but we have had the issue at least once on every computer using Windows.
What has been tested/verified:

  *   It is apparently not linked to our USB firmware since the same device plugged into two different computers (one with the issue, the other without) has different behavior.
  *   Despite the libusb error, our USB device correctly detects the setting of the alternate setting and behaves correctly.
  *   We have tried with libusb version 1.0.24 and the latest version 1.0.27 without any change in the issue.
  *   The only solution found to fix the issue is to manually uninstall all the devices in Windows Device Manager and restart the computer afterward. After this, the problem is no longer present.
  *   The issue is not reproducible (making it more fun).
  *   USB enumeration and USB properties on Windows report no issue when the problem occurs.

If this rings any bells or if you think we could try anything to fix this issue, please do not hesitate!
Thank you for your time and consideration.
Best regards.

I'm using the synchronous interface, and can do everything I want to do in 2.0 mode (with a 2.0 cable plugged into the device)

When the device is plugged directly into a 3.0 port, I can get the list, find the device, release the default driver, claim the driver, open the port, but then when I call the libusb_bulk_transfer(), it times out.

Times out where, exactly?  On which call?  Are you able to open the device and claim the interface?  Have you disabled the default operating system driver?

What kind of card?
Something like a SD card or microSD card?

Hello,

I have developed a LIBUSB program to send locate/claim/open a USB reader/card and send a few commands to the drive and retrieve the data.

This works fine when the drive is plugged in with a 2.0 cable adapter, but if straight in to 3.1, then it times out.

Same code works under Linux for both 2.0 and 3.0 ports.

Is there any  updates to the MACOS version that might help fix my problem?

Thanks,

I still don't know what you mean by that.  It's darned near impossible 
to write a driver that handles multiple device classes, because the 
protocols are all entirely different.   (A libusb app is essentially a 
user-mode driver.)

That's... a stretch, to put it mildly. QSerialPort is a class which is a part of Qt, which in turn is an utterly gargantuan framework.
Personally I find it (Qt) great and almost exclusively use it all the time instead of STL, but even I wouldn't blanket-endorse it for all situations.
