OTG Port question


Dec 26, 2010
Just got a UPAD with a micro OTG USB port and when I connect to my PC, the tablet screen says it is connected and there is a button to push to get access to the storage. However, the tablet just spins a little process indicator for many minutes with nothing getting resolved. In the meantime, my PC's Explore screen adds an item for a removable disk, but when I click on it, it tells me to insert a removable disk...

Any thoughts on why the process won't complete?

As an aside, the Host USB port works well with the second card reader and cable that I tried; the first did not register with the tablet. Must be a fussy USB connection.
