Hi. This may not be the exact correct list to ask, but it is about a USB device, so I thought I'd try here.

I have an application that talks to a device built around a usb-to-serial adapter. The device has the USB-to-serial thing embedded, so if there were a way to know which kext was behind a particular /dev/usbserial-* device, I'd be able to filter out any serial ports that I know could not possibly be the device I want.

Is there an easy way to query a /dev/ node to determine its kext or, alternatively, ask the kext which devices it controls?

Thanks in advance.
