Hi,
I have disabled pcscd with chkconfig and rebooted. After the reboot I attempted
to connect to the
VDI and share my smart card reader again. The same issue occured.
ifdhandler is still messing with the reader while spice tries to use it, I
would have expected the
stopping of pcscd to also stop ifdhandler, but it seems I was wrong. Please
also disable ifdhandler,
I suspect that will solve your issue.
And that worked just fine. I can forward my smart card reader to the Win 7 VDI
now. Thank you.
Good!
Would you consider this to be a bug?
Yes, I think what you are seeing is in essence the same as:
https://bugzilla.redhat.com/show_bug.cgi?id=820205
With this libusb bug fixed, and assuming that ifdhandler properly claims the
device, you should
get a "device is busy" instead when you try to redirect the device when it is
used by ifdhandler.
I'm afraid that unlike devices which use kernel drivers, there is no reliable
way to take-over
the device from a userspace driver like ifdhandler, so the busy error is the
best we can do.
Note that for smartcards the smartcard channel is a much better solution
though, as it allows
use of the card in both the client and guest simultaneously.
Regards,
Hans
