Bug Description
I found that USB to serial dongles such as my FTDI chipset (ftdi_sio driver) dongle no longer work in Feisty. The problem is that brltty claims them before the driver is able to, as I understand it:
[ 6786.276000] usb 1-1.4: usbfs: interface 0 claimed by ftdi_sio while 'brltty' sets config #1
[ 6786.284000] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[ 6786.288000] ftdi_sio 1-1.4:1.0: device disconnected
Removing the brltty and brltty-x11 packages solved the problem. It seems that either this package needs to be fixed so that it doesn't interfere with these devices or it maybe shouldn't be installed by default?

Same problem here with TMote Sky sensor motes (http:// www.moteiv. com/products/ tmotesky. php). This is what happens when I try to plug one:

I also had to uninstall the brltty package.
