There are many games/apps in the wild that use that one (along with other
checks) so it's worthwhile to fix this.

The most common symptom is the 0x2d0c04 device ioctl fixme followed by a crash:

IOCTL_STORAGE_GET_MEDIA_TYPES_EX is described in MSDN:

http://msdn.microsoft.com/en-us/library/aa363413.aspx

Fortunately SecuROM versions that use this check only look at the DeviceType
field, specifically they check for DeviceType == FILE_DEVICE_CD_ROM (0x2) or
DeviceType == FILE_DEVICE_DVD (0x33).

The DEVICE_MEDIA_INFO array of GET_MEDIA_TYPES struct part is completely
ignored (either pass MediaInfoCount = 0 or fill it with whatever
RemovableDiskInfo values).

You can get away with simple implementation.
