Public bug reported:
Binary package hint: librxtx-java
Release: Ubuntu 9.04 Jaunty Jacalope
Package version: librxtx-java 2.1.7r2-4
System: Linux EWI1308 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC
2009 x86_64 GNU/Linux
How it worked before the upgrade:
I connect my USB device to the USB port on which /dev/ttyACM0 is created. I run
my Java application which calls "CommPortIdentifier.getPortIdentifiers()" on
the class gnu.io.CommPortIdentifier. This returns an Enumeration containing a
CommPortIdentifier pointing to /dev/ttyACM0 which I can use to access my serial
port.
What happens after the upgrade:
I connect my USB device to the USB port on which /dev/ttyACM0 is created. I run
my Java application which calls "CommPortIdentifier.getPortIdentifiers()" on
the class gnu.io.CommPortIdentifier. This returns an empty Enumeration,
manually getting the CommPortIdentifier by calling
CommPortIdentifier.getPortIdentifier("/dev/ttyACM0") gives an
gnu.io.NoSuchPortException.
What I've tried to fix this problem:
Downgrading librxtx-java to the version from intrepid. Rebooting to the old
kernel (2.6.27-11), rebooting to the old kernel with the librxtx-java version
from intrepid. Unfortunately none of these things helped. It just doesn't find
the serial ports anymore.
Any help would be greatly appreciated, I really need a working librxtx-
java in order to program some devices on my work.
