>Description:
When loading uplcom(4) kernel module after the USB2Serial device is plugged the first doesn't "attach", so I still see ugen(4) associated with the device and no dev. nodes created.

Here's an extract from `usbdevs -dv`:

Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
  uhub0
 port 1 addr 2: full speed, power 100 mA, config 1, USB-Serial Controller(0x2303), Prolific Technology Inc.(0x067b), rev 3.00
   ugen0

When changing the sequence (e.g. first load, then plug) the device is detected correctly
