After some effort I was able to get this to work. I am surprised that much of the documentation (spartan 3 starter kit, USB 2 Module, Adept documentation) was not very clear on this process atleast for this old board/software combination. I was able to get this working through opensuse 15.x and same should work for other linux distros as well. I also tested this in windows xp with Adept 1.x version and it works. S3 board ====== Connect the Digilent USB2 module to A1 expansion connector Put a jumper in jtag connector to bypass cable. This is indicated in the board. Put a jumper to middle pins of J8 Remove all jumpers from JP1 Software ====== Install adept-2 using RPM or Debian package. Adept link - https://reference.digilentinc.com/software/adept/start. I used latest versions of runtime and utilities. In my case RPM package installed without any issues for both utils and runtime. Read the read me in each package if this fails. Install dependencies specified in readme's of above packages. Most importantly libusb. Perhaps you will have to reboot the machine after these steps. After these connect the board and issue djtgcfg enum and device should be listed. This was my result: Device: Device Transport Type: 00010001 (USB) Product Name: DModUsb1 V0.0 User Name: Serial Number: 10054d008790 Note that there is no name for the device in the above output. (No text after Device:). If there is a name already skip the next step. Add the device to the table using dadutil as follows. In my case I gave the device the name 's3'. Replace serial number as required. dadutil tbladd --alias s3 --conn SN:10054d008790 --dtp USB Initialize the jtag chain. djtgcfg init -d s3 Create your bit file using xilinx ISE. Make sure to setup the FPGA startup clock to JTAG clock in property window of 'Generate Programming file' process in ISE Program the FPGA with the bit file as follows. In my case FPGA had the index '0' in jtag chain. djtgcfg prog -d s3 -i 0 -f <bit file> If you are using windows XP use adept version 1.10 as 2.x did not start in XP. In XP, adding the device to table was automatic however.

I have this old spartan 3 board and USB 2 module from digilent and would like to get them to work in Linux (OpenSUSE 15). I already got ISE 10.1 to work with XUPV2P board by using libusb. For the spartan board however only option I seem to have for programming is through USB 2 module as my machine does not have a parallel port to use JTAG directly. I installed adept-2 and djtgcfg enum shows following: Found 1 device(s) Device: Device Transport Type: 00010001 (USB) Product Name: DModUsb1 V0.0 User Name: Serial Number: 10054d008790 I have the USB 2 module attached to the B1 connector of spartan 3 board. Above does not show the device name and have no idea why. Without the device name I cannot initialize the chain. Any help is appreciated in this regard.
