error micro SD DS0201, I can't connect USB to PC

Hello everybody!

I’ve buyed a Oscilloscope DS0201 in dealextreme, but my problem is when i want store waveform, it appear in the screen error microSD. I’ve formatted in FAT16 anD FAT32, but my problem is the same. Also, I’ve used a 128MB of microSD and 4GB of microSD, but my problem is the same.

Also when I connect USB to PC, windows don’t recognise my DS0201. It’s hardware problem?What I do?

Thank you very much!!!
