This is based on something that Anton Ludin sent to the mailing list.
Reading through the code it seemed that there were scenarios in which
DC_vendor and DC_product were not updated correctly. That's one of the
problems of the declarative approach in QML - it can be very hard to
figure out which code is run when in certain situations.
This may help address the issue with FTDI downloads no longer working on
Android.
