I was using the wrong fd. The following works:
struct usb_device *dev; [...] struct usb_device_handle udev = usb_open(dev); struct usbdevfs_ioctl command = { 0, USBDEVFS_DISCONNECT, 0 }; ioctl(udev->fd, USBDEVFS_IOCTL, &command)
Now the only thing left to figure out is how the libusb library expects us to do this, because struct usb_device_handle; is not implemented in the exported interface.
I guess the solution is to implement the above functionality in libusb itself.
