Comment 8 for bug 700316

The devices I tested this with are (from lsusb):

ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device
ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

That commit doesn't include any of these. The first two are ZWave dongles, the third one is just a single port serial cable on USB (which can have any serial device on the other end, but for my tests I didn't attach any).

Given the increasing number of devices reporting as generic serial cables, blacklisting will probably not work out very well in the long term.
