Tip: How to correctly select the file you need
1. If you know MD5 value of the required files, it is the best approach to make choice
2. If your original file is just corrupted but not lost, then please check the version number of your files. (Method: Click your original file, and then click on the right key to select "Properties" from the pop-up menu, you can see the version number of the files)
3. If your operating system is 32-bit, you must download 32-bit files, because 64-bit programs are unable to run in the 32-bit operating system.
4. There is a special case that, the operating system is a 64-bit system, but you are not sure whether the program is 32-bit or 64-bit. If you encounter this situation, check the file path to see whether there are any other files located in. If yes, please check the properties of these files, and you will know if the file you need is 32-bit or 64-bit.
If you still can't find the file you need, you can leave a "message" on the webpage.

I encounter 9F BSOD crash in my machine and the module that is blocking the Power IRP is CYUSB3.sys.Timestamp: Tue Jan 16 16:24:57 2018 (5A5DDA01)
CheckSum: 0001AD84
ImageSize: 00015000
Translations: 0000.04b0 0000.04e4 0409.04b0 0409.04e4
Information from resource tables:
Can you please let me know if this is the latest driver and will a driver update solve the 9F BSOD in Windows 10 ?
Have you seen 9F BSODs in CYUSB3.sys before ?
Reply: The problem is likely in the IRP.
You’d better DEBUG to see which IRP has a blue screen after execution. It is possible that IRP resources have been released after the execution of that IRP. Some IRPs may call the underlying driver to release the IRP resources, which may cause the problem.
Irp is sent to the lower-level driver, and you should not operate it anymore. If you need to operate it again, register the completion routine. When the lower-level driver finishes processing this IRP and goes up, it will call the completion routine when the completion routine is detected, so that your driver can continue to operate the IRP.
