IBM Blade Server – USB i/o access issue

Dear Tech Team guys,

Setup:
I have blade chasis and 14 number blade server are connected in the blade chasis.

Requirement
Want to use the USB dongle license in Blade server

Concern:
I am not able to use simultaneously USB device port for all the blade servers. I want the solution for the same. If am using one server to another it is termating the first one.

Workaround
I have used USB over Network Server software, but which are not supporting usb donlge device over the network.

Issue:
This software will support for USB devices over the network and not an USB lincense dongle.

Please let us know, if you have good solution.
