Aha... it's assigning the usb_serial_simple driver instead of hidraw. There must be a rule somewhere that tells udev to use this device as a serial. This is an HID device!
I don't know what hp4x converter is, perhaps you had installed some connectivity library for Linux?
Somehow you need to find where in your system there's a rule for HP calcs to load that serial driver. Simply comment that rule out and let the system try yo identify the device, it should see it as hid and load the standard hid driver plus hidraw.
