I am using WINUSB for my oscilloscope devices. The driver works ok on my Win7 64bit computer.

But some users with Win7 64 bit are saying that they get an error "the parameter is incorrect" when trying to install the driver.

Is there anyone who could review the driver package? Particularly the winusb.inf file?

That incorrect parameter error could pop up in all sorts of situations. It can indicate a problem with a disk, or with authorizations or with many other problems. Are those users in user-mode, trying to install the driver ?

I'll ask about the user mode. One user sent me this report with two images attached:
