Okay, I need to classify this bug report into one of the given categories for QEMU. The bug report mentions that `cmd_mode_sense` always reports 0x70 in byte 2, which indicates no CD-ROM present. According to the user, if a CD-ROM is present, it should report 0x01 or 0x11 instead. Looking at the possible categories: there's 'device', 'graphic', 'socket', 'network', etc. The bug seems related to hardware devices, specifically CD-ROM handling in QEMU. Since `cmd_mode_sense` is part of the ATAPI implementation for IDE devices, it falls under device emulation. The incorrect reporting likely affects how peripherals are managed by the emulator. Therefore, the category should be 'device'. device
