 Troubleshooting
 ===============
 
-Using a ACR122 device (and ACR122 only, not touchatag) with libnfc needs some
-PCSC-lite configuration:
-* Allow CCID Exchange command;
-* And if your device have a bogus firmware you could allow PCSC to use bogus devices.
+Touchatag/ACR122:
+-----------------
+If your Touchatag or ACR122 device fails being detected by PCSC-lite daemon
+(pcsc_scan doesn't see anything) then try removing the bogus firmware detection
+of libccid: edit /etc/libccid_Info.plist and locate "<key>ifdDriverOptions</key>",
+turn "<string>0x0000</string>" value into 0x0004 to allow bogus devices and
+restart pcscd daemon.
 
-To do this, /etc/libccid_Info.plist and locate "<key>ifdDriverOptions</key>",
+ACR122:
+-------
+Using an ACR122 device with libnfc and without tag (e.g. to use NFCIP modes or
+card emulation) needs yet another PCSC-lite tweak:
+You need to allow usage of CCID Exchange command.
+To do this, edit /etc/libccid_Info.plist and locate "<key>ifdDriverOptions</key>",
 turn "<string>0x0000</string>" value into 0x0001 to allow CCID exchange or
-0x0005 to allow CCID exchange and bogus devices.
+0x0005 to allow CCID exchange and bogus devices (cf previous remark) and
+restart pcscd daemon.
+
+SCL3711:
+--------
+Libnfc cannot be used concurrently with the PCSC proprietary driver of SCL3711.
+Two possible solutions:
+* Either you don't install SCL3711 driver at all
+* Or you stop the PCSC daemon when you want to use libnfc-based tools
