USB HID Driver stops working after an hour of being idle

[alzomor]

Hi

I have developed a USB HID driver using the hid.dll of windows.
but I face the following problem
If i didn't send any commands to the USB device for About an hour and then try sending again the USB devise don't respont.
In order to get the application respond again I close the application and open it again.

Do you have any sugetions?
Dose Windows OS unload the drivers after timeout of being idle , and how to overcome this problem ? if this is the problem

Hi, sorry I can't help you to solve your problem because I'm a newbie. >"<
Anyway I have a question to ask you. How did you indicated to the PC what device is that? For example if I plugin a mouse to the PC's USB port how the PC knows it is a mouse? Because I'm doing my project & have this difficulty. Hope you can give me some guide. Thanks

Best regards,
Noobie

how to use usbhiddriver.dll

What is your USB device? Is it build by yourself? Are you sure that your hardware is ok?

I'm wondering why not to use windows available drivers. Why did you develope a driver yourself?

My Device is ST72F621J4T
I built the HW & FW myself
I think so becuse my device work good with Jungo windriver
Actually I am using the available windows driver HID.dll , I just built an application to use this dll
