I searched around but couldn't find any real answers so here it*is.

1.
Got T100TAF that I use as a project mini PC but can't find way to power it and use the Micro USB at the same time.
I got Y cable but as reported here by others it will not charge the tab. Did anyone found way to simply solder another USB port on the MB*? I did this couple years back on my Dell 8 PRO to add internal flash drive and it worked great.
Not concerned*how it will look like

2. Thought that I will solve problem 1 with dock, sadly the dock came from T100TA and the USB 3.0 port on it is not recognized. Seen similar post about this but just wondering if anyone managed to get it working.

Thanks
