[systemd-devel] udev rules for MCS7715 USB-attached parallel port

Hi,

I recently bought an MCS7715 USB-attached parallel port,[1] but there
seem to be a couple of problems using it with Linux:

1. The lp, parport, and parport_pc kernel modules are not loaded when
the device is plugged in.
2. After manually loading the kernel modules, /dev/lp0 is not deleted
when the device is unplugged.

I'm using a fully updated copy of Arch Linux. Aren't the default udev
rules supposed to handle stuff like this? Could I send one of these
devices to you for you to debug?
