To display the overlays currently enabled by the cape manager, type:

cat /sys/devices/bone_capemgr.*/slots

On a default Beaglebone Black, it should show:

 0: 54:PF---
 1: 55:PF---
 2: 56:PF---
 3: 57:PF---
 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI

The format of output is:

 Probe [F]ailed Flag
 [O]verride Flag
