Kemper USB Devices Driver

Posted on  by admin

Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device. In Windows 10, the driver has been rewritten by using the Kernel-Mode Driver Framework that improves the overall stability of the driver. Improved PnP and power management by the driver (such as, handling surprise removal). What is odd is that the USB driver is recognized within windows10 Device Manager as Line 6 - Helix Floor and also within Windows Control Panel items as Heilx Control Panel yet both HX Editor (2.9) and Editor (1.19) but yet Line 6 software just wont' acknowledge connection within the software. You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps: 1. Right click on Start and select Device Manager. Double click to expand 'Universal Serial Bus controllers', right click on the Host Controller,click 'Uninstall' and click 'OK'.


This section describes the generic WinUSB driver (Winusb.sys) and its user-mode component (Winusb.dll) provided by Microsoft for all USB devices.

In versions of Windows earlier than Windows XP with Service Pack 2 (SP2), all USB device drivers were required to operate in kernel mode. If you created a USB device for which the operating system did not have a native class driver, you had to write a kernel-mode device driver for your device.

Windows USB (WinUSB) is a generic driver for USB devices that was developed concurrently with the Windows Driver Frameworks (WDF) for Windows XP with SP2. The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll) that exposes WinUSB functions. By using these functions, you can manage USB devices with user-mode software.

Winusb.sys is also a key part of the link between a UMDF function driver and the associated device. Winusb.sys is installed in the device's kernel-mode stack as an upper filter driver. An application communicates with the device's UMDF function driver to issue read, write, or device I/O control requests. The driver interacts with the framework, which passes the request to Winusb.sys. Winusb.sys then processes the request and passes it to the protocol drivers and ultimately to the device. Any response returns by the reverse path. Winusb.sys also serves as the device stack's Plug and Play and power owner.

Note WinUSB functions require Windows XP or later. You can use these functions in your C/C++ application to communicate with your USB device. Microsoft does not provide a managed API for WinUSB.

This section describes how to use WinUSB to communicate with your USB devices. The topics in this section provide guidelines about choosing the correct driver for your device, information about installing Winusb.sys as a USB device's function driver, and a detailed walkthrough with code examples that show how applications and USB devices communicate with each other.
