It can be used to find out which drivers you need to install to get a USB device running based on the VEN/DEV strings that the OS reports, or to identify an unknown device.
The database comes from: http://www.linux-usb.org/usb.ids
The database is locally stored on the SD and can be updated online. Before you can use this application, you will need to download a copy. To do that press "Menu->Update DB".
I refresh and upload this database weekly.
To do a wildcard search, use the '%' character.
Please email me with any bugs/problems/feature requests. I cannot reply to market comments which can make debugging difficult.
