smartcard does not work with firefox

[mvogt1]

Hello,

since last year, the smartcard support from the vmware view client is unusable.
Firefox does not start, thunderbird or other smartcard apps hang.

This happens when the windows version of the vmware view client is used.
The attached demo program show this behaviour.

Its from:

https://github.com/LudovicRousseau/PCSC/blob/master/doc/example/pcsc_demo.c

The demo should runs in less than a seconds, and needs an insterted
smartcard. It only queries basic reader calls from the PCSC API "winscard".

Here are some benchmarks. (linux->linux works fine)

Horizon client	remote OS (time)
linux	linux 0.2sek (good!)
windows	linux 20secs
linux	windows (does not work)
windows	windows 90secs (hangs sometimes)

RDP sessions (windows client to windows Server) is fast too, with around 2 secs.

As a result, the windows horizon client to a linux machine is not usable
with VMWare Horizon and firefox/mozilla.
The demo only issues a few calls, where firefox will issue thousands of
them.

Attached program contains pre-build binaries and source code.

After a windows re-install the problem is gone.

This demo program showed it with runtimes of around 10 seconds and sometime more,

but because it was not reproducible and only happend on my machine, its gone now.

After a windows re-install.
