Hello,

Trying to get some clarification on the following statement in terms of using mixed devices.   We are using all 4 ports on the hub.  All devices are 2.0.  However, Two of the devices connected are using 2.0 Full Speed (12Mbps) and two of them are using the High speed (480Mbps).   Does this mean that all of the devices will be limited to 12Mbps?

 

Thanks,

Phil

 

Remarks: this USB hub has only one transaction translator (TT) for all downstream
USB ports. Please try not to connect any USB 1.1 device to the USB hub; otherwise
all devices on the hub will be slowed down to the USB 1.1 speed (12 Mbps). If you
only connect USB 2.0 devices to this USB hub, all of devices on the hub can work with
USB 2.0 high speed (480 Mbps), if they support USB 2.0 standard.

Yes. In such case all devices will be limitted to 12Mbps, because they have to share the same TT.
