I have been looking around the internet, but these issue seems to be unresolved even on other threads.There's an Unknown USB device (link in compliance mode) issue on my computer. The thing is, I only have 3 devices that are plugged into my USB ports --- a mouse, a keyboard and a WD external hard drive. Anyone has any suggestions? Do you think it's alright if I just disable the device from device manager? Actually I'm not too concerned but the issue is that it ties in with another issue-KMode exception not handled (ntfs.sys). Apparently, this issue happens when there are drivers not installed properly so I thought that these two issues may be related.
