Carl: In my mind, running the driver provided with libusb-win32 as a filter driver and changing configurations and/or selecting alternate interfaces is really dangerous as the "real" driver may have pipes open to the configuration and/or on the interface which is being switched from possibly causing some real problems since the "real" driver does not know that the configuration and or interface has been yanked out from under it.

I am not so sure here. But the HID driver can be the issue. That is why I asked Stephan to add the native Windows HID backend to libusb-win32. When I first started with libusb-win32 with PICkit 2, the same BSOD happened. It turned out that I could not use the libusb-win32 filter driver since it is an HID device but has a second configuration.

Message-ID: <fab...@ma...> Content-Type: text/plain; charset=3DISO-8859-1 I'm using the latest version you can download. I reckon I'm going to try this: Open the device try reading the feature report if that fails then call usb_setconfiguration try reading the feature report again end if every frame try reading the input report using usb control messages close the device But on this vista computer, reading the feature report without setting the configuration always fails. Hopefully with the filter driver, reading the feature report will work the first time, so it will never call usb_setconfiguration and thus never lock up the computer forcing them to reboot. But I haven't tested that yet.

Because of some Gmail madness, please add a no-meaning extension to the zip file (libhidwin32.zip.gmailsucks or similar). ;-) Thanks a lot in advance.

So maybe it is a good idea to put it to an FTP site so other people can get it as well.
