Sorry for jumping in the middle of the thread, but I too have a
similar problem with Metrologic Focus MS1690 Barcode scanner.
Currently, I am getting the device as bi-directional serial mode but I
want to make it work as a USB HID Keyboard device. In the
manufacturer's manual there is a barcode to configure the device as
such. After this I can see from dmesg that first the device gets
registered as USB HID v1.11 Keyboard, the I guess the scanner power
cycles disconnecting the USB and again gets registered as a new
device.

How to make this device work on Linux?
Please note this link http://forums.gentoo.org/viewtopic-t-852806.html
says that "They tracked it down to the scanner registering itself as a
keyboard and then power cycling and registering as a custom POS
device. I contacted the manufacturer and they sent me a barcode
(99940) which when scanned locked the device into USB keyboard mode.
It then worked fine as a standard keyboard."
