I have a WASP pen scanner that seems to be recognized by the kernel:

usb-0000:00:03.3-1.7
usbcore: registered new interface driver usbhid
drivers/hid/usbhid/hid-core.c: v2.6:USB HID core driver
and creates a device in dev:
/dev/input/by-id/usb-Marson_Wasp_Barcode_USBi-event-kbd
but I'm not sure how to read from it. Where is the ASCII output from the
unit going, theoretically?

It's a distinct device - you should be able to read directly from that
/dev that's created when you plug it in. When in X it typically works like
a second keyboard, inserting the text wherever a keyboard's entry would
end up.
