I ordered the deal extreme USB host cable on Dec. 4.http://www.dealextreme.com/details.dx/sku.51045
$4.60 including shipping.
I got it today December 20th from China. I've goofed around with it for a couple of hours. The cable has NOKIA CA-157 label on it.
It works with some external drives. But as has been described above the Archos support is picky. It does work with several Corsair Flash Voyager sticks 4 & 8 GB. It would not work with some older PNY Attache sticks. 1GB and 512 MB. I have 2 oldish external USB reader/writer adapters... one worked one did not... These are both very cheap. The 8 in 1 SIIG USB reader/writer failed. The Media Gear 9 in 4 worked. I used a 2 GB Transcend SD flash card with both.
I read elsewhere that these multi card readers will only read the first slot.. For the Media Gear this was the SD card. For SIIG the sd card is the second slot. The first one could be CF..which I don't have any media for.
I could play MP3's off the sticks... Movies would start. But after 30 seconds they would freeze.. Photos work great.
I tried several external USB disk drives that use external power. I could not get any of these to work. I did not try any other peripherals yet.
But my Flash Voyager sticks are the ones I use around my house to move media via sneaker net. They work so I am happy. And the price was certainly right.
