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
