USB disconnect issue [WiredBox.Net

> You are probably having driver conflicts. That happens when you get too many
> USB devices on at the same time. You need to isolate which devices conflict
> with each other and then only power or plug one of the devices at a time.
> Check for system dumps at the time of the failures and analyze them as they
> can show which drivers are failing. You may have to clean up old drivers
> there left behind when older devices are removed or you may have to rebuild
> your system from scratch to eliminate them.
