Reference Manual for uTrust 4701F and uTrust 4711F Readers
For Windows 7 and Windows 8, the value for uTrust 4701 F, contact part, would be
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_04E6&PID_5724&MI_00\Devic
e-Instance-xxxx \Device Parameters\WUDFUsbccidDriver
that for uTrust 4701 F, contactless part would be
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_04E6&PID_5724&MI_01\Devic
e-Instance-xxxx \Device Parameters\WUDFUsbccidDriver
The one for uTrust 4711 F, SAM part, would be
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_04E6&PID_5725&MI_00\
Device-Instance-xxxx \Device Parameters
that for uTrust 4711 F, contactless part, would be
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_04E6&PID_5725&MI_01\
Device-Instance-xxxx \Device Parameters
Device-Instance-xxxx will be an auto-generated combination of four hexadecimal numbers, separated
by ‘&’, so this modification has got to be made for every physical reader/slot intended to be used on
the machine in question. The reader has got to be plugged in at least once for the mentioned keys to
exist and the driver has got to be restarted for this setting to take effect. (Unplug and re-plug the
reader).
To be able to work with synchronous memory cards using our MCard API, the same setting will have
to be established.
See appendix B for some sample code sending Escape commands to the reader.
