AW: It may happen, depending on the assignment of USB memory devices connected to the USB hub, that the media drive indicator does change the address of drives assigned before, due to dynamic assignment of drive letters by the system.

If you have problems, while playback from USB, make sure that the USB disk is formatted correctly. In this case, note the following: In Windows Vista, Windows 7 and Windows 8 you have the option of a quick format or full format. For problems with the disk, full format is recommended. Make sure that the checkbox at formatting options -> Quick format is not enabled. Make sure that the FAT32 file system is selected. Do not use NTFS, HPFS and EXTFAT file system settings.
