duplicate usb device ids

duplicate usb device ids

[Michael Friedl]

I got a new CCD 800B barcode scanner, but it has the same device id like 
an other product from Tenx, which is on the ignore list for hid devices.

Found nothing about the old product so I report it here.
If the old one get removed from the ignore list the bardcode scanner 
works perfect!

Im not sure how to handle duplicate ids..

Let the HID maintainer know, he should probably just remove these ignore
values now that the manufacturer has fixed the device.

The device IDs were added by Remi, added to CC.

Remi, are these really different devices with the same VID/PID? You were 
stating that the devices are not HID-compilant, which contradicts what 
Michael is saying ...
