[gentoo-user] USB barcode scanner

[dhk]

I have a 2-dimensional usb bar code scanner that I'm trying to get 
working ( This is the exact one if interested: 
http://www.barcodesinc.com/metrologic/ms1690.htm ).  It scans, but 
nothing gets displayed.  How can I get the focused window/terminal to 
understand that the device should be treated as stdin?  The output from 
lsusb and lsusb -D is below.  Thanks,

It doesn't look like you have the HID keyboard version.  I have an ID
Tech IDT4439U which when plugged in behaves like a keyboard.  In the
following lsusb output, notice the iConfiguration and bInterfaceClass
parameters.  My wild guess is you will need a driver.  Also you may want
to verify you have CONFIG_HID* enabled in your kernel config.

HTH,
