This may be more of a Windows than a Rust question. I'll ask nonetheless: I have written a program to control a USB missile launcher toy. github.com GitHub - conqp/usb-missile-launcher: Library and controller programs for the center USB... Library and controller programs for the center USB missile launcher It works as intended on Linux. On Windows however, the underlying USB device is not detected. When I list the USB devices, it does not show up in the list of connected devices. When I plug it in, however, I hear that Windows sound that plays when a USB device connects, yet the list of connected devices as seen by rusb remains unchanged. I have not much experience in OS development under Windows, so I don't know how Windows handles USB devices and what I need to do to make the device being detected, so that I can communicate with it, as I can under Linux, where it does show up in lsusb . Any hints on how to get Windows to make the device accessible by rusb is appreciated.
