This is solved by uninstalling "brltty" as posted in this question (https://answers.launchpad.net/ubuntu/+question/5503) So, you should do this:
sudo apt-get uninstall brltty This problem is happening again in Ubuntu 11.10 with Xilinx ML605 developtment board. Something must be done because this is not normal. It's really annoying having to figure out what the problem is every time you use a USB UART device. And even more annoying to find the problem and find this solution. I took me about 4 hours to find and solve this problem, even I am related to computers, Ubuntu and Linux. Imagine how annoying it is for anyone not related to linux and how many devices using UART through USB there are. Let's deactivate BRLTTY default or contact with BRLTTY developers to not claim the USB interface by default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874181 Title: brltty daemon prevents creation of ttyUSB0 device link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
