11 Notes for the use of USB
devices
Digital Content Issues
• Only FAT (DOS) formatted (initialized) portable memory is
supported. Errors in this formatting can result in unreadable
content. If such problems appear try to re-format the card. Be
aware that formatting the card will also delete all the content on it
(pictures, music, …).
• The length of a fi lename or directory name is limited to the length
specifi ed by the FAT12/16/32 fi le systems.
• The access and response time of the content on a device can differ
depending on the type or brand of the device.
• The access and response time of the content on a device will
decrease the more unsupported or corrupted fi les are on the
device.
USB Memory Device Issues
• Devices connected to the USB port of your TV must be “Mass
Storage Class” compliant. If your device (digital camera. MP3 player,
portable hard disk, …) is not “Mass Storage Class” compliant it will
not be detected by the content browser of the TV.
• The following subsets of the Mass Storage Class specifi cation are
supported:
• The implementation of the TV is based on the “Universal Serial
Bus Mass Storage Class Specifi cation Overview” (v1.2, June 23,
2003) including all documents referenced by the document. The
document can be found on the USB standardization website
(www.usb.org).
• Full support of the USB Mass Storage Class Bulk-Only Transport
(bInterfaceProtocol = 50h).
• Full support of SubClass Code = 05h; SFF-8070i spec.
• Full support of SubClass Code = 06h; SCSI transparent command
set.
• For large USB memory devices, when you are in the Content
Browser, it may take a long time before you can access your fi les.
• When using a USB portable hard disk: Due to the high power
consumption of the hard disk, it is advised to use the external
power supply of the portable hard disk to guarantee proper
working under all conditions
