[Bug 367833] [NEW] librxtx-java doesn't find serial ports after upgrade to Jaunty

[Ardjan]

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.
