    I am working for a smart card reader company, and was checking Windows 7 with
    our existing drivers.

    I noticed that on installation Smart card readers get an extra driver
    (scfilter.sys, some class driver).
    This would be fine with me, although i am not sure what it does exactly...

    Next to that, whenever I insert a smart card, Windows 7 tries to install a
    device!!
    Weird for me, but as long as it works, I in fact do not care too much ;)

    But unfortunately in some cases, like: 'combined' drivers using a
    bus-driver, a virtual reader/card driver,
    this prevents the drivers to work?
    In the case of the bus driver it does not load the other function drivers,
    the virtual reader driver (where a buddy driver takes on the role of the
    card) the reader/'card' insertion is never noticed.

    Is there anywhere where I can find info on this and on how to solve this??

    Thanks!
