LG GSA-E60N can't read/write disks from usb interface

Title pretty much says it all. I can read/write cds and dvds while the drive is outside of the usb box and connected to the ide controller of the motherboard. If I try to connect the drive using the usb box it is recognized by the os but can’t read or write at all. I already tried different os and pcs: xp, vista, 7 and ubuntu lucid with no luck. Any suggestion?

Thank you in advance.

Never mind, I just switched to a new psu and now is working again. Merry xmas. :slight_smile:
