Communication failure of USB2.0 under CBuilder

[luka]

Hello, engineer，
I try to use nrComm control and U disk communication, in these days of research found a concentration problem
1. In Windows 10 64 bit operating system, using demo provided by you to install nrusb and WinUsb drivers fails.
2. When USB and active windows 7 are opened, USB device can be installed in windows.
3. In Windows 7 32-bit operating system, nrusb and WinUsb can be installed, but the "nrusbpipepair1afterreceive" event cannot be triggered when sending a string.

Hello, engineer
Thank you for your reply!
However, I tried according to your method. In the "usbosrkitdemo WinUsb" example, the service option is not displayed in the "usbosrkitdemo WinUsb" example. I guess your program does not recognize the type of the driver. If this problem is not easy to solve, can you help me with the third question I asked. "In Windows 7 32-bit operating system, nrusb and WinUsb can be installed, but the "nrusbpipepair1afterreceive" event cannot be triggered when sending a string."

Hello, engineer
If it is not easy to recover, can you give me a program according to the USB parameter information (vendor ID: 058fh; product ID: 6387h); the vendor ID, product ID, pipein and pipeout of this program can be modified dynamically

Hello

You can try following demo:

Demos\USBIODemo\usbiodemo.dpr
Demos\USBPipeDemo\usbpipedemo.dpr

They have IO operations with usb pipes
