Hello again! I would like to give an Update that a mere System Re-boot has accomplished what a System Shutdown could not achieve for such a long time. A desperate attempt led to to Re-boot the Machine while the device were plugged in, & it did the trick eventually..! All the Yellow exclamation marks have gone now, both of my devices are getting detected properly, & therefore Iam now able to use each of these without any hiccups!
Lastly, What could be there so special about a Re-boot over a System Shutdown in this case? Does a memory retention (Error Code 38) signify any sort of impending Hardware issues or a Malfunction of sort? Please guide.
