5 Jonathan Warner - Computer Repair Sacramento CA - Knowledge Base: Hardware ID Root Legacy_Saskutil 0000 and Root Legacy_Sasdifsv 0000. What causes the device manager to report new hardware detected and startup errors? While completing a TDSS Rootkit removal and data recovery virus removal, I came across this error. Of course, no new hardware had been added. Also, there were no unknown devices in device manager just previous. This error took me by surprise, so I took stock of what just changed on this system. Nothing that I would expect to cause this error. SUPERAntiSpyware had just been uninstalled...
