Questions tagged [winusb]

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, and 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, which 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.

USB (WinUsb) isochronous bandwidth management

I've been experimenting with isochronous USB transfers using WinUsb, and it turns out that WinUsb always sends data as fast as possible: WinUsb_WriteIsochPipe packetizes the transfer buffer so that in each interval, the host can send the maximum…

How to create a WinUSB-based driver that reads data from a bulk endpoint as fast as possible

I'm trying to write code to make it so that a microcontroller can communicate over USB with a PC. I think that the majority of the code is in place, and communication generally works fine so long as it's slow (> ~5ms per message). However, I'd like…
