print/cups on NetBSD 5.1.3 usb printers not visible

[SiTLar <sitlar%gmail.com@localhost>]

Hello,

I'm having troubles after updating print/cups to 1.54. CUPS is not
able to detect my USB printer, which is actually online. usbdevs shows
its presence:

$ usbdevs
addr 1: OHCI root hub, vendor 0x1022
 addr 2: Color Jetprinter 550 , Lexmark International, Inc.
addr 1: EHCI root hub, vendor 0x1022

However, the CUPS USB backend is returns with a weird error message:

 Failed to check whether 0419:3201 has the "usblp" kernel module attached

Is there a usblp module on NetBSD? May be I've messed up with some configs?
Thanks in advance!

Best regards,
Ilya
