Good resources of WinUsb if you develop using this low levelīuilt on top of the low level wrapper is a more usable api to performĬommon USB operations. exec_function_setupapi ( 'SetupDiGetClassDevs', byref ( guid ), None, None, flags ) #args: arguments of the C++ function called def exec_function_winusb ( self, function_name, * args ): def exec_function_kernel32 ( self, function_name, * args ): def exec_function_setupapi ( self, function_name, * args ):Ĭ++ HDEVINFO SetupDiGetClassDevs(_In_opt_ const GUID *ClassGuid,_In_opt_ PCTSTR Enumerator,_In_opt_ HWND hwndParent,_In_ DWORD Flags) from winusbpy import * from ctypes import * from ctypes.wintypes import * from winusbclasses import DIGCF_DEVICE_INTERFACE, DIGCF_PRESENT api = WinUSBApi () byte_array = c_byte * 8 guid = GUID ( 0xA5DCBF10 L, 0圆530, 0x11D2, byte_array ( 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0圎D )) flags = DWORD ( DIGCF_DEVICE_INTERFACE | DIGCF_PRESENT ) hdev_info = api.

Low level api offers three methods for invoking functions from threeĭifferent dlls. from winusbcdc import ComPort p = ComPort ( 'My USB Device' ) # friendly name as shown in device manager # or p = ComPort ( vid = 0xF055, pid = 0x9800 ) p. Install WinUsbCDC pip install winusbcdc python setup.py install USB CDC DeviceĮnsure your device has the WinUSB driver configured. Which simplifies a lot of C++/windll/ctypes messy interactions offering Winusbcdc.ComPort(name, vid, pid) class which roughly matches theĮxposes the same WinUSB api: - A 1:1 wrapper over WinUsb which allowsĬalling C++ functions directly from involved dlls. Rather unstable and has data loss issues on Win 10. On windows without using the built in usbserial.sys driver as it is

It’s intended for communicating with USB CDC (virtual com port) devices WinUsbCDC is a python package for communicating with USB / CDC devices
