Unfortunately, it's an out of production model and I very much doubt the vendor will fix the devic= e, even if they could. It would likely need it's USB chip replaced and no vend= or would do that for an unsupported device. As for how it passed USB-IF, I don't know. This is why I believe a USB quirk patch would be most appropriate, to detect this device by it's VID:PID and slightly change how it decodes the unique device ID. --=20 You may reply to this email to add a comment.
