FTDI chip not recognized anymore


I use a Nexys 4 DDR board for some time now. I never used to have problems when programming the device.

Today I tried to program the device as I did many times before, but it didn't work. It said I should check whether I connected the board properly and so on. So I checked the Jumper settings and everything. Now I tried to see whether the FTDI FT2232HQ chip is recognized. When using the bash command "lsusb" the chip is not listed anymore.

Does anyone know what the problem could be? How else could I check whether the FTDI FT2232HQ chip is working or not?

I need to finish a report and therefore I need the device working as soon as possible, thank you for your help.

Hello, @hearos!

In order to help you with your request, I need some details. First of all, how is your board listed in the Device Manager(you can access Device Manager from the Control Panel)? Second of all, right click on the listing and click properties. In that new window, go to the details tab and search for "Hardware Ids" in the property combo box. Please tell us what you see listed after selecting the "Hardware Ids" property. 

Best regards, Ovidiu
