AS the title says, this happened about 1 year ago and I fized by Downgrading, upgrading, Downgrading... something and then the USB started to work again. The SD slot works perfectly, I can load games from there. I'm sure it is a Software issue, since the USB HDD spins and the HDD LED blinks. I tryed with different HDDs and USB Pendrives! Maybe the Linux running on WODE is having some problems with mount/automout. If it cloud be factory reseted... maybe this would fix it.
