Don't know if you have seen this already, but there's a virtual CCID
device implementation in QEMU. See http://wiki.qemu.org/Features/Smartcard
Should be a good starting point. Combine it withe the VHCI driver from
USBIP and you have your CCID device.
It is first time I hear about QEMU virtual CCID. Now we have all parts
needed for USBIP VHCI and QEMU virtual CCID, just glue those together.
I wonder if it is wise to even create virtual CCID "core" to Kernel.
There is few other readers that can use that too, actually I think all
USB readers that have unique USB ID (blocking out those which uses
USB-serial converters with common IDs).
As I see that CCID still more complex as serial device I will still look
implementing it as serial as now.
