FTDI produce a range of serial devices which utilise the FTDI sio driver in Linux with
various capabilities.

=== ECS i-Buddie USB dock === 

This uses an FT8U100AX USB bridge as seen in the foreground of the top right picture. This chip combines multiple functions which include serial I/O.

This device fails to operates on correctly on a USB 2.0 port and a connection to a USB 1.1 port or hub is essential.

This board is manufactured by FTDI as an FT232R evaluation kit which has an almost full break-out of the chip pins. The jumpers either select bus power or isolate the device and also allow to selection of either 3V3 or 5V I/O.

=== Clone FT232R===

Devices as the one in the background of the top right picture are generally FT232R clones yet they can easily achieve 1 megabaud. 2 megabaud has also been tested but not extensively. They also support the libftdi API in Linux.
