Just fill in the data according to the USB spec.

Can you be more specific?
How to fill it in?

There should be a development kit with functions to call.

BulkOnly Sample from DDK.
Pipe0 is a Control Pipe, which requires the cooperation of driver and AP.

If there is a development kit, it is another matter.

Now I use the windows driver and want to write commands into the EP0 of the U disk.
Daniels help.

Oh, I thought you wrote the firmware of the hardware. I think Windows U disks have drivers, so you don’t have to write drivers with ddk.
After inserting the U disk, the windows driver will execute the control pipe command.
If you want to write EP0 through the xp driver, do you need to rewrite the windows driver? Or you can look at CreateFile, WriteFile does not work.

I added the EP0 command to the firmware.I need the host to send the command to EP0, but I just don't know how to send it through the windows driver.
Use DeviceIoControl + SCSI_PASS_THROUGH to send commands to EP2, but somehow write to EP0.
WriteFile has also tried and always returns an error.
