what does 'lsusb -v -s 3:3' and -s 3:4 show on Ubuntu?
First you need to know this:
I have severals usb to serial adapters. All of those have the same
HL-340 chipset.
when i plug two of this serials i get only information in Bus 003 Device
002 and Device 003. This give me a possibility to do lsub -v -s 3:2 and
lsusb -v 3:3
Then i take out one device and put another and get Bus 003 Device 003
and Device 004
If i take out both and replug then i will need lsusb -v -s 3:5 and lsusb
-v -s 3:6
It's like an incremental device ? I don't know.
David, this is the output on Ubuntu

this is only one difference: the line who talks about the Bus!
I would say that the openwrt serial shown by udevadm info is faulty,
but I suspect that the Ubuntu one is faulty as well, just in a
different way.
It's true.
Best regards.
