Hi Alex, thank you for the quick response.
I'm using libusb-1.0.9_rc3. I get a similar problem using qthid. qthid crashes before showing up the gui. I think, libusb has a problem multiple open and closing the device. So I just changed the code of qthid to open the device only at the beginning and keep it open. Then qthid works.Hi Volker, Although using a slider to tune hardware pll is a bad idea, I don't think the crash you see is because of that. It sounds more like an issue some people have seen on debian with libusb 1.0.9-pre-something Which version of libusb do you have? Can you run the included examples and qthid without crash?
PS: The slider in your example isn't doing much as it has only one step ;-)
I know, but it was the easiest way to show the problem. Perhaps I should downgrade libusb. Volker
