PID list

Cypress USB-Serial devices are just "dumb" bridges, not modems, so they should be blacklisted.

VID for Cypress is 0x04b4 and I'm attaching a screenshot from documentation that lists all the CDC-ACM PIDs that should be blacklisted. I think it's safe to block all devices from 0x0002 to 0x000A.

This is the document http://www.cypress.com/index.cfm?docID=47671

Attachment is an image but set as text/plain mime type. It can be seen by downloading it and renaming it to .png.

I added the PIDs to the greylist where we list all USB<->RS232 adapters; thanks.

Fixed in git master and the mm-1-4 branch.

Thank you very much for the quick fix, and sorry about the image. I have not used Bugzilla for a very long time, so maybe I messed up something.

No problem. Actually I thought I could just change the mimetype on the uploaded image, but couldn't find how. I know I could do it in the gnome bugzilla, not sure why not here.
