Now I'm developing an application for our USB device. I use WinUsb.sys for
the USB driver. The device is defined for using bulk read and bulk write
endpoints. I was succeded in installing WinUsb.sys on my system. I can see
the device infomation on registory and USBView.exe application as I designed.

The problem is that I was succeeded in using WinUsb_WritePipe(), but I was
failed in using WinUsb_ReadPipe(). When I call WinUsb_ReadPipe(), the
function never return or never complete I/O processing.

Any advice will be welcom. Thanks in advance.

Are you sure the device has data for you to read?

Hi,

If you are using .Net you can use this component for Bulk devices:
