The Sony Ericsson Device 0017 USB WMC OBEX Interface driver is typically associated with older Sony Ericsson mobile phones. Specifically, it allows the computer to communicate with the mobile phone via USB and supports OBEX (Object Exchange), a protocol used for transferring files between devices, such as transferring photos, contacts, or other data between your Sony Ericsson phone and a Windows computer.

The Windows Mobile Device Center (WMC) is the software required for syncing and transferring files to and from your device. This specific driver, WMC OBEX Interface, is needed for the OBEX file transfer capability to work correctly.
