Having established that usb_modeswitch wasn't switching the K3520-Z's mode when invoked by udev to do so, and suspecting usb_modeswitch_dispatcher was to blame, I decided to write my own udev rules file (/etc/udev/rules.d/kludge_k3520z.rules) so as to bypass usb_modeswitch_dispatcher. It is attached. It causes udev to invoke a shell script (/lib/udev/kludge_k3520z) that runs usb_modeswitch with precisely those options required to switch the K3520-Z's mode.
