Got some more time to poke around the system. If did change the
ExecStart in /lib/systemd/system/systemd-udevd.service to:

  ExecStart=/lib/systemd/systemd-udevd --debug

`journalctl -u systemd-udevd` now contains this:

  Apr 01 13:56:58 alice systemd-udevd[424]: worker [458] /devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.4/3-1.4.3 is taking a long time
  Apr 01 13:56:58 alice systemd-udevd[424]: worker [459] /devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.4/3-1.4.4 is taking a long time
  Apr 01 13:56:58 alice systemd-udevd[424]: worker [473] /devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.6 is taking a long time

Those devices map to these usb devices:
  Bus 004 Device 004: ID 03f0:231d Hewlett-Packard 4 GB Flash Drive
  Bus 003 Device 010: ID 0a5c:2101 Broadcom Corp. BCM2045 Bluetooth
  Bus 003 Device 008: ID 03f0:2514 Hewlett-Packard 

The Notebook is a HP EliteBook 8560w with integrated WLAN/Bluetooth.

I'm going to attach the systemd-udevd journal and lsusb -vvv output
