This is a CH340 (chip) question NOT an ftdi question

Dec 22, 2014 at 20:02 comment added jvc26 Unfortunately @Phil Vallone the issue is that there is no unique serial to identify the device via udev. In order to detect and identify a unique device, you need something unique to differentiate them. These devices have the same iSerial, so you can't diff them on that, and they share the same Product and Vendor IDs - so there isn't a differentiator ... Thanks for your help, unfortunately it doesn't fix this issue!
Dec 22, 2014 at 19:59 comment added jvc26 Yeah - I've seen that, but unfortunately, suffer the same linguistic issue!

Dec 22, 2014 at 12:44 comment added PhillyNJ My link is to my answer which talks about creating udev rules for each device.
Dec 21, 2014 at 19:25 comment added jvc26 Unfortunately, this isn't really an answer to either: the question (as it doesn't answer whether there is a way to assign a new serial number as one can do for FTDI chips), or resolve the issue (as the udev serial for all these boards, like the Leonardo, is 0, therefore udev can't distinguish between multiple boards attached to the same computer.
