Regarding PC/SC devices limitation

Hello Michael,
By reading the documentation, I stumbled upon :

AutoAttachToKernel Set this to 0 to disable the device being available to the host whenever a remote user is not using the device. The default is 1 for all platforms. Setting this to 0 is sometimes useful to prevent a server OS driver binding to the device and disrupting its redirection.

I mostly use Virtual Here for redirecting PC/SC smartcard readers, which are theorically limited to 16 concurrent devices by its library, and to 10 on Windows.
But I only use 2 maximum at once on each client.

So I wonder if PC/SC is executed in server or client side when a device is bind with VirtualHere. And if I set this parameter to 0, would this mean that I can bypass this limit ?

Thanks and have nice day
