Ok, ANOTHER question from me tonight… So as I’m trying to get stuff uploaded to my board, suddenly when I try to upload I get this error which I’ve never had before:
Cannot open DFU device 0483:df11
I read the posts on this thread Cannot open DFU device error and couldn’t really get anywhere. I ran the DFU setup again but it didn’t fix the problem. I don’t know why there is an issue now, I can only assume that in the past few days when I was trying to get my windows defender working correctly (my virus scan feature was gone) I messed some of these files up.
Anyways, when I first got the error tonight, I got a popup telling me I had to turn off memory integrity in windows core isolation… which I did, but that also didn’t fix the problem, and NOW I can’t get memory integrity to turn back on because it says the driver “STTub30.sys” is incompatible which is a whole other problem…ARGH!!!
When I look in device manager, the board seems to show up as STM Device in DFU Mode, under universal serial bus controllers. Unless I’m looking in the wrong area.
Do you guys know what I need to do to fix this? I can’t update that driver from the device manager, it says the most current version is installed. Do I need to delete it? I don’t want to screw my system up. I’m tearing my hair out in frustration here, I thought I had this all set up and now it’s all gone sideways. HELP!
