Hey! Been working on getting my DC online for some time now, finally got my last part in the mail, Zoom 3095. When I plug it into my pi i get a fleeting singular light and it goes away. Ive seen this issue with other people, but haven't found a solution. Im using this LVI:

Any help would be appreciated! Spent months getting the money to get this and I'm super poor haha
