Heh, I wrote the last one wrong in the last comment, but put in the
right USB IDs when I did the patch ;)

You'd need to change it again on updates, AFAIK (unless it's a conffile?
not sure). However, this should be brought up upstream so that these
lines can be added to blacklist to make sure it doesn't cause further
problems.

I have double-checked my records:
My serial device stopped working for the first time (within years,
as recorded by minutely logs) after the reboot following an upgrade as
logged below in my /var/log/apt/history.
According to that log, in that upgrade, network-manager and
network-manager-gnome

Ohh, I've seen this fixed in a recent commit in modemmanager trunk,
assigning this bug to myself to upload at least to natty; then consider
this for an SRU (it's simple udev rules).

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
What do you mean, increasing number of devices reported as generic
serial? My understanding is that there aren't so much, and in general
they shouldn't be affected too badly (plus, it's reasonable to have such
a device to use an old modem, too). Nice catch though. What I'll do now
in this case is
In my specific case, the devices I use are ZWave, and they have this
habit of sharing USB ID with genuine serial cables.
But that doesn't matter. Network-manager made one of my genuine serial
cables unusable, which means that even if it had an old serial modem
attached it would probably prevent
The network-manager + network-manager-gnome hypothesis may not be true.
I encountered this problem with Kubuntu 10.10, which doesn't have the
network-manager-gnome package installed. LiveCD test is enough.
How I did the test:
strace cat /dev/ttyUSB0
When it doesn't work, it gets stuck at:
Purged network-manager and all packages depending on it, rebooted, and
the serial devices seem fine now without the reloading of usbserial. I
can't use it properly in Kubuntu anyway, so bye bye it goes. I was
keeping it under the impression that it will pull kubuntu-desktop with
it, but it didn't!
It turns out that the problem is an incompatibility with the packages
network-manager + network-manage-gnome
Whenever these are installed, usbserial becomes intransparent
(i.e., physical and logical devices are present, but there is no thoughput
through the serial interface).
