I have a couple of powered USB Hubs that work inconsistently. For simple stuff, such as transferring a file from one external drive to another, they generally seem to be OK, but when trying to do multiple transfers, they fail. They also seem to be inconsistant when seeking to link phones and so on.
When I link the devices directly to the motherboard using the USB connections on the computer, I do not have a problem.
Is there some issue with the USB drivers
that allow the system to differentiate between the different devices that are linked to a single hub?
