Spark HW just flashes lights (left-to-right) ; USB / Device not recognizing

[ryukikass]

Hi everyone, I have a problem that I'm hoping someone has encountered or knows how to fix:  My SparkLE HW is not recognizing (which is connected to USB, I've tried USB 2.x and 3.x ports & even a different usb cable).  Am in Windows 10 (w/ latest updates) and the SparkLE HW controller isn't even coming up as a recognized OR even un-recognized USB device (in other words, not showing up in Device Manager).  What happens is it just flashes lights (scrolling from left-to-right).  I have the latest HW firmware.  Weird thing is the SparkLE controller is recognized (and works) in 2 of my other Windows 10 pc's but those are for my work laptop & my wife's pc).  Need it on my dedicated music PC! 

Other info:
*The software plug-in of Spark 2 works in standalone & in my Cubase DAW without issue.
*I have latest versions of Arturia Software Center & MIDI Control Center.
*I've uninstalled & re-installed the Midi Control Center and the USB Midi Driver twice to no success.

Anyone have any idea?

Finally got the SparkLE to work.  I followed these steps from Roland and it appeared that some devices were unrecognized/hidden so i uninstalled and re-booted and plugged it in and now recognizes!  Hoping this will help someone w/ their frustrations:

Hello...I had precisely the same experience during the 701 update aside from I had green quick blazing lights, not yellow
For my situation, it couldn't be fixed by any of the techniques recommended and is at present with DJI for fix. I trust i'm off-base, yet it seems like you may need to do likewise.
Starting now and into the foreseeable future I'll be refreshing through DJI Assistant 2, not from the iPhone.
