This is yet another case of https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/153662 https://bugs.launchpad.net/ubuntu/+source/hal/+bug/175182 and similar. Yes, the "fix" is to remove brltty. As I explained in 153662, it's hard for blind people do debug why their braille device doesn't work since it's that precise braille device which allows them to access the machine... Luke, you need to comment that entry from the udev rules file too. BTW, I see that you have commented the 0401:6001 entry from the udeb version of the udev rules too. I don't think it's really necessary: will really people use a usb-to-serial converter to install Ubuntu nowadays? While people using Seika or some HandyTech devices do need to install Ubuntu with them.

[Bug 874181] [NEW] brltty daemon prevents creation of ttyUSB0 device link
Public bug reported: After upgrading from Ubuntu 11.04 to 11.10, I no longer found a '/dev/ttyUSB0' for my serial-to-USB converter. The device is part of a Xilinx FPGA board and is a "10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device". Every time I plugged in the device, dmesg showed the device coming up and 'brltty' did *something* to it. At this point, no device was present in '/dev'. [ 5181.130942] cp210x 1-1.4:1.0: cp210x converter detected [ 5181.203658] usb 1-1.4: reset full speed USB device number 5 using ehci_hcd [ 5181.296637] usb 1-1.4: cp210x converter now attached to ttyUSB0 [ 5181.623749] usb 1-1.4: usbfs: interface 0 claimed by cp210x while 'brltty' sets config #1 After removing 'brltty', the '/dev/ttyUSB0' device appears again like it used to.
