I installed an new ESXi 5.1, when I connect with vsphere client (running on windows 7 - 64 bit) and I plug an usb smart card reader on my pc, I only see "Connect to USB device" -> "Shared ACS CCID USB Reader 0.

If I choose this option I get this message back "The remote device connected to Shared ACS CCID USB Reader 0 is disconnected"!!!

Looking on event tab I see this error: "The currently available license does not permit the use of shared smart cards."

I didn't find any statement about share smart card licenceing!

What kind of licence I need to run shared smart card feature?

If I connect to the same VM with vmware workstation 9 client I see another option not shown in vsphere client

If I use the same vsphere client on another pc with windows XP the option in "Connect to USB Device" are two:

- Shared ACS CCID USB Reader 0

- Advanced Card CCID USB Reader

Why this option doen't exists in vsphere running on my windows7 64 bit pc?

Thanks in advance.
