And this the last: <key>IOParentMatch</key> <dict> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>idVendor</key> <integer>3245</integer> <key>idProduct</key> <integer>36886</integer> </dict> <key>bInterfaceClass</key> <integer>255</integer> <key>bInterfaceSubClass</key> <integer>0</integer> <key>bInterfaceProtocol</key> <integer>0</integer> <key>IOProbeScore</key> <integer>60000</integer>

This is the second half: <key>CFBundleIdentifier</key> <string>dev.paulober.MotorolaTetraPeiDriver</string> <key>IOMatchCategory</key> <string>dev.paulober.MotorolaTetraPeiDriver</string> <key>IOProviderClass</key> <string>IOUSBHostInterface</string> <key>IOUserClass</key> <string>MotorolaTetraPeiDriver</string> <key>IOUserServerName</key> <string>dev.paulober.MotorolaTetraPeiDriver</string> <key>bInterfaceNumber</key> <integer>0</integer>

Oh yes sorry that was a past issue the later part it the content of the dict of my first IOKit personality: <key>IOTTYSuffix</key> <string>0</string> <key>bConfigurationValue</key> <integer>1</integer> <key>CFBundleIdentifierKernel</key> <string>com.apple.kpi.iokit</string> <key>IOTTYBaseName</key> <string>tetra-pei</string> <key>IOClass</key> <string>IOUserService</string> part 2 in the next comment
