Libusb-win32 Driver Download !NEW!

I've faced a problem getting my libusb-w32 based program to detect devices.The program has to detect digital cameras, and I need to automatically install driver filter for any new camera to be detected without any manual work. I've used install-filter i --class=6BDD1FC6-810F-11D0-BEC7-08002BE2092F , i. e. installing filter for MTP devices, and it seemed to work. But today I tried it on a clean machine and found out it actually only seemed that way. Tried install-filter with different parameters - no luck.The only way I was able to detect devices at all was to use the inf-wizard.exe. It installed the driver, enabling my program to detect devices, but also disrupting the original Windows functionality for digital cameras. Then, I've uninstalled the libusb driver, installed the original windows driver back, executed install-filter i --class=6BDD1FC6-810F-11D0-BEC7-08002BE2092F - and the program is still able to detect devices.The question is: how to automate the process so that any new camera is detected without any work required from a user?
I have a PCM RPT-800A UPS, connected to a Windows 2012 machine. I would like to use NUT for communicating with the UPS. But shortly after installing libusb-win32 for this UPS, the device in Device Manager starts to "blink" (disappear and appear again), looking like it's disconnected and connected again randomly, but frequently (once in 30 seconds, approximately). When I uninstall libusb-win32, it's automatically substituted with default "HID UPS Battery", which works perfectly (no "blinking"), but doesn't give any data to NUT.
if "libusb-win32" driver is used for UPS, at first it works OK, but in a few hours it spontaneously starts to disappear and then appear again in Device Manager as if someone unplugs the UPS USB cable and plugs it in again.
I do really need to use NUT with this UPS (PCM RPT-800A). So the question again is: how do I make this "libusb-win32" driver to be installed correctly so it won't disappear and appear in Device Manager by itself?
I spent a considerable amount of time on 3 different Windows OS versions, desktop, laptop and MS surface only to realize I should've read the full instructions. The only reason I didnt is because Im familiar with MS taking control of drivers and using that tool to force a different version - the instructions were straight forward. Silly me. Ive not noticed any difference in performance between libusbk or winusb and both worked on Win10 Home, Pro and the edition that comes with Surface 6 Pro which is basically Home minus a few features. Libusb-win32 however fails to recognize the camera in ShootOff.
I recommend you to use libusb-win32 generic driver utility to generate a driver for your device. However, if windows says your device is malfunctioned and does not recognize it, this means your device is not capable of doing enumeration correctly. You need to check control transfers and descriptors. After a correct enumeration windows will start to search for a driver for the device.
I have installed libusb-win32. And I could successfully create the driver for it and the device is shown under libusb-win32 devices. But when I try to debug the code, it shows error initializing emulator. Can you please suggest what the problem might be?
-The USB port that you use for emulation and debugging is different than the one that you use for USB data transfer. You should not change drivers of emulation device. Are you sure that you use a different usb port for communication?
-c5505 usb host tool contains a driver for c5505 but it only works with 32 bit PCs , not works for x64 systems. libusb driver will work for you and host software that provided in libusb examples work for you if you want to perform bulk or interrupt transfers. So you don't have to use "c5505 usb host tool" and follow the steps.
-You need to have a firmware that is able to do enumeration before installing drivers. There is a sample project called 'usb' in ti program files directory. This is an HID device example but it gives an idea.
After I install LIBUSB I should create the driver for my USB from the list of available devices right? But I can not find C5515USB under the USB ports. Sometimes it shows unknown device and sometimes the device is not shown. I tried replacing the cable with another and checked but still the usb port is not visible. What should I do?
This is about a problem in your firmware code. Firmware must be able to do control transfers (enumeration) in order to be seen by windows. When you plug your device you should see that windows searchs for a driver (even if cannot find it) . After that, device appears in infwizard window ,same as the name written in string descriptor. You can match your code with a working code to solve problem.
Download the LibUSB-Win32 driver and extract it somewhere temporary. It can be found at www.libusb.org, however, for some reason my machine did not like this version, so I found another version that appeared to be tailored specifically for the AVRISP MKii here: AVRISP mkII libusb drivers for Windows 7 / Vista x64 MightyOhm
Now if you haven't installed the Jungo USB drivers, then you can simply plug in your AVRISP MKii, but when it asks whether you wish to install the drivers for it automatically or manually, choose MANUAL. If your did like mine and went ahead automatically and installed the stinkin Jungo USB drivers anyway, then you'll need to do the follow:
How to replace the Jungo USB drivers:
A. Go into your Device Manager and expand the tree under "Jungo". If you see "AVRISP mkII" there, then you'll need to replace that driver with the LibUSB-Win32 driver. Right-Click and select "Update Driver Software" and then choose "Browse my computer for driver software". Then simply navigate to where you extracted your LibUSB-Win32 drivers and let it do it's thing. If it refuses to replace it or says that Windows deems the current driver the latest, then you'll need to find a better/newer copy of the LibUSB driver. You can also try uninstalling the Jungo driver first, but my smartass PC kept reinstalling it automatically everytime I plugged the AVRISP MKii back in---regardless of me manually clicking cancel!
If the LibUSB-Win32 driver installed correctly, the AVRISP MKii should now appear under "LibUSB-Win32 Devices" instead of the Jungo tree. This is important to make sure of because the Arduino IDE will NOT work with it as long as it appears under Jungo.
I really really hate to grave dig, but none of this worked for me... If you need to replace the Jungo driver and windows still won't let you although you've uninstalled all of Atmel Studio (like me). It's easy to get it working... Don't fight Jungo, trick it.
I also wanted to add. Some AVR ISP programmers implement the mkII protocol, but these are shown as a Serial device rather than USB. If this is the case no driver changes are needed and it works with both AVR studio and Arduino.

The Mac and Linux instructions usually say something like "plug it in and party on" but folks like myself with Windows have to set up a WinUSB Driver (libusb-win32 or libusbK) as dfu-util uses those libraries to speak to USB devices.
If you plug in a device, the vast majority of Windows users want the device to 'just work.' My non-technical parent doesn't want Generic USB drivers so they can flash the firmware on their mouse. I, however, as an aristocrat, sometimes want to do low-level stuff and flash an OS on a Microcontroller.
Zadig is a Windows application that installs generic USB drivers,
such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices. It can be especially useful for cases where:
- you want to access a device using a libusb-based application
- you want to upgrade a generic USB driver
- you want to access a device using WinUSB
Here you can see me finding the ST device within Zadig and replacing the driver with WinUSB. In my case the device was listened under STM32 Bootloader. Be aware that you can mess up your system if you select something like your WebCam instead of the hardware device you mean to select.
Now I can run dfu-util --list again. Note the before and after in the screenshot below. I run dfu-util --list and it finds nothing. I replace the bootloader with the generic WinUSB driver and run dfu-util again and it finds the devices.
libusb-win32 is a port of the USB library libusb 0.1 ( ) to the Microsoft Windows operating systems (Windows 2000, Windows XP, Windows Vista and Windows 7; Windows 98 SE and Windows ME for versions up to 0.1.12.2 ). The library allows user space applications to access many USB device on Windows in a generic way without writing any line of kernel driver code.
Vista/7/2008/2008R2 64 bit are supported from version 1.2.0.0 since a Microsoft KMCS accepted digital signature is embedded in the kernel driver libusb0.sys.
