Microsoft disabled kernel debugging over a 1394 connection in the latest versions of Windows 10. You can force the appropriate settings by using: Code: bcdedit /add {dbgsettings} debugtype 1394 bcdedit /add {dbgsettings} channel <channel> This only actually worked for one or two releases of the insider preview, and now on 16257 it does not enable kernel debugging over 1394. I was wondering if anyone knows if it would be possible to use network, USB, or even local kernel debugging and use the driver replacement command to replace the 1394 debug driver with a slightly older version? Or are the supported kernel debugging protocols defined elsewhere in the system?
