Just did a search at XDA and found this pic of the internals of the stock USB dongle. Definitely some circuitry involved.
One tinkerer reported that the output "hosting" voltage at the 40 pin is 10VDC and the dongle regulates it down to 5V. Not sure my geriatric fingers could readily remove the 40 pin connector on the dongle board and successfully solder a cable in its place.
Will just have to wait for a younger, more nimble person to build these "to order".
Connecting a usb 3.0 hub to the type-a port on the dock seems a better solution to me.. although for the right price, I'd buy a 40-pin to y-split type-a cables.. for charging AND connecting up some usb peripheral while charging.. if I read it right was the intention of the OP...
I have an ASUS USB "box" and a nice iodata card reader which function just fine, but the resulting christmas tree protruding from the top of the tablet is less than edifying.
Even a short 40 pin M to 40 pin F "extension cable" would work, especially if the M end were "low profile" and right angle cable exit, as is done with a variety of micro USB cables. Then the USB "box" converter could be plugged into the F end of the cable.
i'm new TF700 user
and i'm happy to see that i'm not the only one that looking for this cable
Ohhh... It looks bad. I want to reassemble it with a dongle but it looks impossible
Hmm, moment. But I think asus con

I think you refer to an OTG (on the go) adapter that actually converts the TFxxx 40 pin conn into a master USB enabling it to connect to several USB devices (mouse, card reader) even by using a usb hub. an EXT USB HDD will probably not work as it draws too much current.
I have bought one from EBAY (10-14 USD) but so far never tried it
The port on the TF series is not technically USB-OTG. OTG is a single port with only 4 conductors,and the adapter is wired in such a way to signal the device to activate host mode; without the adapter the port is a standard slave port. The TF series actually contains the wiring for 2 separate ports in the 40-pin connector, along with a few other interesting things. The charge cable exposes the standard slave port when connected to a PC or other host device, while that adapter is required to expose the USB host interface. The difference is that in the dock, both can technically be active at the same time, while USB-OTG with it's single set of conductors allows only one or the other at a time.
I don't know how use it.
