Problem: my USB smart card reader connects and disconnects with my virtual machine (Windows 7) rapidly like so: http://tinypic.com/r/a0uyw3/8
Because of this, any attempt to use the reader while in the virtual machine results in it "not being connected". I know that there is no issue with the USB plug or port because it works solidly in the OS X interface.
I'm running VMWare Fusion 6 on an iMac (OS X Mavericks) and Windows 7 64 bit.
The smart card reader is an SCR331 model.
