Problem with the usb midi hub input.

Hello! there's a problem using the translator classic.
I have a USB Midi hub 4x4 by Prodipe. When i select one of his 4 input channel on the translator, it say: Cannot open midi input device name_of_the_input" because it is already in use.
It only work if i select the input of my external audio card that is a Edirol UA-4FX.
I really need to use it with a device plugged on the usb midi hub..
Somebody can help me?
Thanks

Hi,

opening a MIDI port is exclusive. That means that another program has access to your MIDI input device. Close it and you will be able to open it in MT!

Best regards,
