[Spice-devel] Native USB redirection does not work - (remote-viewer) did not claim interface 0 before use

[Sigbjorn Lie]

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.

Please see below for the contents of /var/log/messages.



Regards,
Siggi
