Your problem is most likely the USB port on the older computer. It may be malfunctioning, or it might jsut be that the computer was built at a time when the USB implementation wasn't up to what it is capable of today, which is highly likely.

The Sonic Cell may require USB 1.1 at the least and very likely that would be marginal bandwidth for the device, with USB 2.0 likely being the preferred.

**You might find a BIOS flash and newer USB drivers for the computer on the mfrs website, may or may not provide functionality here.**
