Just a teardown of an ordinary magic USB HUB, ( 7 ports magic ), that has invaded all the shops, for quite some time now, I believe you all know it in a way or other, it's in every shop these days .
Conclusion: Usable after rework and proper soldering. Not for high power or speed
Good point is that it has switches for all the ports
I got a Technics RS-TR575 for maintenance, here is how it was done (1st part inspection and evaluation).
