[DC LoCo] USB Issues

[Paul Flint]

Dear Brian,

The sad fact is that the USB disk controllers are often made cheaply.

I have had a similar problem.  The answer turned out to be a new USB disk 
controller.

Something like this can be a great troubleshooting aid:

I have two, but be warned, one is a bit flakey...

Regards,

Paul
