The Dell Venir 8 will do it. Using the Yoga ac adapter and power cord connect to the Venir 8. Using the Venir 8 dell cord connect from Venir 8 to Yoga 2 micro usb port. Unit charges and the Venir 8 also has a full size USB connector which can be used at the same time. Works great!

 

YMMV.

Yes I have a Dell Venue 8 Pro and the Vener8 adapter which allows simultaneous charging and use of usb port. I tried it on my new Yoga 2 win and it works as well. Here is the link, I initially spelled it wrong. It is VENER8.

Enjoy.

What resistor value have you tried derekgroves?

Only thing that can be changed in the hardware configuration of the OTG Charging adapter is the value of the resistor between pin 4 and pin 5 of the microUSB plug on the tablet side.

USB standard states three values 124k, 68k and 36,5k Ohms.

This source on XDA developers used 100k Ohms for Sony Xperia, and this one 40,2k ohms for Galaxy S4. 

If someone would be able to try these 5 values, and neither of them would work, then the last try is to measure the resisatnce of the "Lenovo Thinkpad Tablet Y USB 3.0 cable" and try to replicate it with microUSB 2.0 version .

 

I look forward for a definite answer, because the possibility of charging and using USB devices at the same time (in fact docking) is a key feature for me.

 

Thanks

Has anyone got this to work yet for more that a reported one time fluke? 

 

I bought this to keep connected to a scanner and it does not appear possible to keep it running while also keeping it connected to OTG!

 

Is this possible? 

 

Has anyone asked Lenovo?

We have a Lenovo PC IdeaTab and needed the option to be able to charge the tablet continuously and also have a usb keyboard attached, a monitor via mini-HDMI and also a USB network adapter.

 

It took me 2 or 3 times to get it right but we did!!

Let me know if that link doesn't work!

 

Hope that helps someone out there.
