I've had my player for about 4 months and LOVE it! However, I experienced my first problem last night: the front USB port stopped recognizing my card readers.
I have been using a card reader to read movies from a 4GB SD card. No problems until yesterday -- I plugged into the front USB port, then card reader got power (light turned on), but the "drive" never showed up in the Devices menu. I never received the message about thep player recognizing a new USB drive either.
I then tried a different card reader -- same results: power, but no question, and no Device recognition. :-(
Powered the player off/on several times, to no avail. Looked through Settings but found nothing about the USB ports. (I didn't try the back port because my wireless dongle plugs in there... which works fine.)
The card definitely has movies and is easily readable and recognized by my Samsung TV in another room.
Anyone else experience this? Is the USB port broken, and the player needs return? Can it be reset somehow?
