Hi,
allthough the answer is offtopic for cdc-acm-driver, i will answer,
because maybe it helps other people in future.

Hi Johan
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?
I can tell you exactly, what is going on. If the scanner switches to
ProductId=0720 (0c2e:0720) the scanner is working in Serial-Mode. If you
want the scanner let work as serial device, you have to use the driver
metro-usb. The manufacturer has this driver, but that one is outdatet
and doesn't compile on actual Linux kernel.
I found an actual driver, which compiles even with kernel 3.2
<https://gitorious.org/other/metro-usb/commits/master>
In HID/keyboard-mode, the Scanner identifies as ProductId=0720
(0C2E:0200). If you want to let the scanner work in keyboard-Mode, you
have to scan Code Number 3 on the following document:
<http://entwurf.ddnetservice.de/scanner/Factory_Recall_Defaults_39.doc>
If you use keyboard-mode with alphanumeric Barcodes, you have to set
your keyboard-Layout correctly. In my case, i have to set the scanner in
german-keyboard-mode. You find all scancodes for configuration on the
manufacturer-website:
<http://www.honeywellaidc.com/en-US/Downloads/Docs/Pages/default.aspx?pid=1690>
Don't bother to contact the technical support, if you have some more
problems.
