If I try (after rmmoding the hid module):

  insmod usbserial vendor=0x04b4 product=0x5500

I get in the logs:

  usbserial.c: Generic device with no bulk out, not allowed.

Is bulk out really needed or could usbserial be made to work without
it?

I tried google for "Vendor=04b4 ProdID=5500" and zip.

http://www.linux-usb.org/usb.ids lists it as a:

  HID->COM RS232 Adapter

and the hid driver does grab it by default. I was unable to make
hiddev0 function as a seial port though...

/proc/bus/usb/devices says (If I parsed it right):
