Problems with Brother printers and the usb:// uri

After following the instructions at Brother's linux support page:

I managed to get my Brother DCP-130C working fine, printing several documents. However, I came back to print today and CUPS throws an error stating that my printer is disconnected and that it'll retry in 30 seconds. I tried deleting the printer and using the CUPS wizard to set it up again, but although CUPS could detect my printer was connected and ran through the wizard fine, upon trying to print a test page I was still in the same situation.

I eventually came upon the above post in the Gentoo forums, and the problem was fixed by changing the device URI from "usb://Brother/DCP-130C" to "file:/dev/usb/lp0". This is obviously not ideal, as I had to override the restriction on file uri's in the config file. Have I done something wrong or is this a bug?
