Thanks a lot for the reply. We will look at issue 1 you mention. We don't have any special settings on this cable yet, so 2 should not be a problem.
We've seen that the Actel configuration file seems to break the transfer into many small "chunks" of data, so the SVF file has lots of instructions to send out 128 bits. In comparison the Xilinx SVF file seems to send the data in big blocks, so...

Hi,
Just a short comment on the cable/driver selection.
There are two reasons why UrJTAG should know about the cable:
1. to know the correct USB VID/PID
2. to initialize the FT2232 ports correctly
Without 1, ftdi-mpsse cannot determine which USB device should be connected and fails with the error message you mentioned. From that I'd conclude that your FT2232D based cable is not...

We tested configuration of the Actel ProAsic3 FPGA under Linux and it still took 50 minutes. We have tried using different cables and get the same results (Generic FTD2232, OOCDLink-s, and some other).
When we tried using the option "driver=ftdi-mpsse" we got the msg "Couldn't connect to suitable USB device. Error, cable connection failed!"
When we use "driver=ftd2xx-mpsee" we get the...

Hi. We are trying to use an FTD2232D based cable to configure an Actel ProAsic3 fpga. Using the parallel port cable configuration times are acceptable, but with the USB cable things get real slow. It configured OK but took 40 minutes!
I see from the developer wiki that UrJTAG has support for FT2232 in MPSSE mode. To use that functionality should I select "Generic FT2232" cable? Or...
