description |
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.

Impact:
This bug is somewhat hardware specific, affecting all users of the USB serial controller, device 10c4:ea60.
Test case:
With the current version of brltty in Oneiric, brltty takes over any device using the above mentioned USB serial controller, whether it is a Braille display or not. This is because one of Brltty's supported displays uses this USB serial control internally for ocmmunication. The brltty package in oneiric-proposed has the udev rule for this controller commented out, allowing other users of devices based on this controller to work properly.
Regression potential:
All users of the supported Seika will have to load Brltty manually, as the udev rule for their device is commented out, to allow other USB serial controller users to use their device as a proper serial device.
