The version of the FTDI drivers is 2.14.1.2 of 14.9.2021 they are in the device manager under USB serial converter A and B. Interestingly, the USB ports which I had to deactivate (com3, 4, 8 and 9) use the same FTDI driver while COM 6 and COM 7 use Microsoft drivers. (I've attached the screenshot again). The Windows-settings are made by our IT-department. I don't know them and I can't change them. I've looked at the update history and they were no recent updates. However, I've updated some drivers manually, but this was some weeks ago and Vivado recognized the boards afterwards Screenshots2.docx

The boards work now. I am deactivated com 3 and 4 for the nexys board or com 8 and 9 for the arty board. (see screenshots). Could it be that drivers are being loaded twice or that there are drivers of a previously installed version are being loaded? @zygot I am using WIN 10 pro and Vivado 2022.1. The I cant see any rev number on the board. Both boards were bought one year ago. The boards are now visible in USB View. Before, they were just visible for some seconds (See my post above) Screenshots2.docx

Hello, my problem is back. Both boards are neither recognized by Vivado nor by Adept. Screenshots1.docxThe LEDs on the boards are on and I use a powered hub. The Arty board is new and my nexys board worked yesterday. I do not use the boards simultaneously When I connect one of the boards there is a reaction in the device manager and in USB View it appears as "USB Composite Device" with iProduct = " Digilent USB Device". Interestingly, the device name vanishes after some seconds and "Port#0006.Hub_#0001" appears. The line remains highlighted in green. (See the attached screenshots) Any Idea what this could mean?

Hi Zygot, thank you for your answer. To avoid misunderstandings: I am not using both boards at the same time. It's just that I teach two different classes at two different schools and each school uses a different board. Anyway, Vivado works now with my Nexys board. I think the trick was to run the ADEPT utility before starting Vivado as you recommended. Once Adept recognizes the Board, Vivado recognizes the board even without Adept being started before. I can't use my Arty board now for some other reason, but I will test Vivado with the Arty board as soon as I've got a replacement. If I don't post anything during the next days, it also works with the Arty board. Anyway It's good that the fault happened during testing my boards and not during teaching in class. Best regards fx62

Hi, thank you for your answers Adept doesn't recognize the Hardware. Tried "Open new Hardware Target" and connect to local host. No Target is listed there. Stopping hw_server didn't help either. I've reinstalled Vivado several times. It also didn't help. I've also deinstalled the drivers USB Serial Converter A and B. I did a CPU reset on the board. No effect. The board is connected to the computer (The power LED is on) and when I connect the board to the computer the drivers USB Serial Converter A and B are being installed by the computer and it is recognized as diligent USB device. What else can I do?

Hello, I am using a Nexys A7-100T and an Arty a7-35T board with a Windows 10 computer. Both boards worked well. However since yesterday, Vivado does not recognize the boards anymore. Auto Connect only connects to localhost. Installing Vivado again (with cable drivers) didn't help. I've also tried the hints in https://digilent.com/blog/what-do-you-do-when-your-board-is-no-longer-detected-by-vivado/ and it seems that the Windows device manager recognizes the boards. I tried the boards with another computer and they were recognized. Has anyone an idea what to do? Thanks in advance. fx
