Bought a data charge hub from Aliexpress in 2015 and still working well without any bios changes. Also works fine with Dell Venue 8 Pro running Win 8 think it needs the micro USB replacing each time there is a reboot with the Dell only. SWITCH IN MIDDLE POSITION.
Previous links broken and just spent some time finding the item as it has no maker's name on the casing!
finally tracked down:
F17172/F17173 4 Port Micro USB 2.0 OTG Charger HUB Cable Adapter Splitter For Tablet MP3 USB Phone Keyboard etc Basic version
on Aliexpress. brand name said to be XT-XINTE. PAYPAL available from this seller. click the colour you want or you will not progress and use Firefox as neither IE nor Chrome would let me check out!!
Hope this helps.
