Hi, searched the net but didn't find anything helpful pertaining to this.
My system only has one USB Enhanced controller (USB 2.0). When I have plug in multiple external USB 2.0 HDs, they all get assigned to that controller, and they have to contend with each other for the bandwidth. This becomes an issue when i'm transferring from USB drive to USB drive, as the bus is saturated.
The biggest problem is when i'm doing these transfers, my internet download speeds drop from nearly 2MBps to 1MBps, because i'm saving a 3rd attached USB drive, which is of course on the same bus as the other two.
So my question is, is there anyway to give USB bandwidth priority to certain devices (or even applications), kind of like a QoS? I want my internet downloads to have full bandwidth on the bus, then the remainder used for the other two USB drives for their copying operations. I'm aware I could save my downloads to a local drive, but I don't have a lot of space on those.
Thanks
