You have some kernel extension that is matching to the IOUSBInterface of your device and preventing the IOUSBHIDDriver from matching to the device.

You can use the following to search for the offending kext:

% find /System/Library/Extensions -name "Info.plist" -exec grep -H 1155 "{}" \;

This will search all the Info.plist files for one that contains "1155", the idVendor of your device. Judging from the IOProbeScore of 100000 and the values in the ioregistry, the kext in question is doing a vendor specific match by specifying idVendor/idProduct/ bcdDevice/bConfigurationValue/bInterfaceNumber.

what to do so HID explorer works with this HID device?
