Bug Description
Connecting a DUALi NFC reader causes a never ending loop of mtp-probe operations, seen in the syslog
The following udev blacklist stops the problem:
/etc/udev/
ATTR{idVendor}
ATTR{idVendor}
# Don't mtp-probe any DUALi
#ATTR{idVendor}
product 0601 is of a USB with a VENDOR interface that provides PCSC with a driver
product 0600 is of a USB with a VENDOR interface.
There may be other products with this vendor Id that exhibit the problem.
