Hey everyone.
I had an idea for a hardware hack.
Seeing as there are a lot of devices that you cannot use a usb otg cable alone to connect a flash drive (hp touchpad being one of them)..
My idea is a cable/battery hack. using a micro-usb-usbA cable and a portable usb charger i am curious if there is a way to splice the battery in-line with the cable.
Such as micro-usb to USB-A modifying the battery charger to put another usb Male end on the other side so that you can just plug your flash drive into the one end and the male end into the otg cable.. kind of eliminating the entire y-cable/second cable spaghetti situation.
i'm just brainstorming a few ideas to kind of simplify the carry-on mess of cables some of us handle.
Is this a valid idea? or am i asking for nightmares with the wiring/backfeeding power/etc???

Does anyone know if I purchased one of these can the Transformer then read memory cards or use other USB peripherals?
no one has tried yet, try it for us and find out!
I would if I had the tablet. If it does it would be a major plus.
Well we know for a fact that the 40 pin connector that is used to hook up the tablet to PC and charger through USB allows for USB host, we just don't know if it would be so simple that all we have to do is use a female to female converter.
I would think that it would work, because that's how you transfer files to the tablet. Not sure about peripherals though. If this does work it would easily make this better then any tablet.
if I can get myself to put down the money and if someone posts a link I'll try it.

I meant usb female to USB female since I don't have anything with microUSB just wanna test host.
Just bought http://www.amazon.com/gp/product/B000BSN4UY female to female adapter, I'll test USB host I guess
The tablet only has a micro, so I guess I don't understand why you would buy that item.

The tablet doesn't have a micro port, it has a proprietary 40 pin to USB male cable with a proprietary 40 pin socket. So you need atleast reg female to reg female to get host at the minimum.
Never mind just figured it out. You are going to use the micro usb cable that can with the tablet and hook up the female to female. Sorry.
I thought the tablet did have a micro usb host?
only ports are the proprietary connector used for hooking it up to the PC/charger/dock and mini HDMI out. But the proprietary connector supports USB host.
i have found similar threads in other sections.. but i am sure if it would work with motorla xoom.. so the plan is simple; i will cut off 2 old usb cables and i will collect the female ports and connect them together.. then i ll plug this on to the male usb part of the regular motorola cable.. the question is; will it work?

What are you trying to accomplish?
If you want to connect something to the Xoom in USB host mode you just need a "real" USB/OTG cable/adapter-a prime example is the Motorola Camera Connection Kit which is only a small cable with micro usb male and USB female ends. You can't use the Xoom usb cable for host mode...it doesn't have the correct pin configuration.
Same view here, forget bodging a physically correct cable, the pin outs count, buy a USB host cable, the Archos one works.

I was wondering if there is any such device / cord which would convert the Asus proprietary plug on the transformer to a USB cord or something so I could plug in different things without having to buy the keyboard....
Yes it does exist:http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/External_USB_Adapter/
Could you charge the tablet with a regular USB cable using that adapter?
Only when in deep sleep or turned off - but it charges.

No because the USB adapter linked only outputs 5v on the USB port, its not an input.
The USB socket is the wrong type for normal USB cables used for charging, but even a USB-A to USB-A adapter wont allow charging and may even destroy the USB adapter (well, it might not, but I certanly wouldnt want to try it!)
That is sort of what i was afraid of. I was hoping that since I can use the propietary cable, I would be able to switch to a longer cable with the help of the adapter.

Just attach an usb3.0 cable to the propietary cable. Then you have a longer cable.
I'am using this with the tablet and charger.
It has to be USB 3.0 cable? Dang, I actually do have an older extension cable somewhere (forgot all about it until I read your post) but it is pre-3.0, but hey, if i find it I will at least give it a try, not like something would brake, right? Right??
hmm...I had asked this in my thread, but no one has given me a straight answer. Looks like it wouldn't work even with Male A to Male A. I already bought one, so maybe I'll give it a try. Has anyone done so before?

Yes, it must be a usb 3.0 cable.
I have this one and can charge the tablet with this cable attached to the propietary cable and the asus charger
Just tried it again and it is now charging.
That is cool, but I was hoping it would be in a "cord" form because imagine you would have that sticking out from your device, then on top of that you would have your usb plug sticking out as well...
Also, would this work with something like a wireless keyboard and mouse? (the wireless receiver is USB)...
I would like to know if this exists, as if it doesn't I was thinking about making it. As the title may be confusing to understand, maybe describing what I'm trying to do will be easier to explain.
I going to create a dock in a family mini van for a tablet. This tablet will have limited storage space, but has usb otg capabilities. Thus hooking up a flash drive with movies on it would be the goal.
Now running a female to male cable would be fairly easy, however I want to be able to have the tablet charge and still use the usb port to access the usb cable. Thus I need a cable that may be spliced cable with three ends. Where two ends are for usb transfer and another to supply power to the devices. Or if there is another solution, I am up for it.

I have seen Y cables for such a purpose.
If you want to do charge/power and USB host at the same time
you will need the plug into the Android to be an OTG plug with a grounded ID pin.
The other end will go to the flash drive.
If you apply 5V to the Vbus/Gnd your device has the possibility to use this power.
Of course this is an odd situation and it may ignore the 5V and only use its own battery.
Experimenting will show you if this will work without a driver hack.
Has anyone gotten an OTG cable to work with a micro-micro-USB extension cable? Every combination of extension cable and OTG cable kills the OTG functionality (but still allows power).
I figure the extension cables are just straight-through wires. No idea why it would kill the data lines.
I'm using a Y OTG+charge cable for a car install. The micro-USB end is a straight plug. I'm using a micro-USB extension to provide a right angle plug to the tablet. I can't find a Y-cable with a right angle plug.
I would try to figure it out with a multi-meter, but have you tried to get a probe in the end of a micro-USB plug?

I remember reading somewhere that USB otg and charging only works if you plug the splitter and power into the tablet first, followed by the other attachment (wifi, storage, keyboard, etc.)

USB OTG and Y cables?
Sent from my SHIELD Tablet K1 using Tapatalk
The OTG Y splitter works just fine by itself for OTG, sync, charge, etc. Yes, I know how to use the OTG cable.
My issue is, when I plug an extension to the OTG cable, the OTG function doesn't work. Assuming the extension is just a pass-through, there's no reason why this should happen. And I've tried multiple OTG cables and multiple extension cables.
Nope, it's well known that extension cables don't work, even for normal usb cables - loss of signal or power over distance I do not know, but it's a sad occurrence. I've got a 5m microusb cable that doesn't charge at all, which I can only attribute to it's length.
I'm not saying that it always fails to work, but if you've tried several cables it's safe to assume that the extension cable just isn't workable in this case.
After some surgery, I figured it out. It has nothing to do with signal/power loss. To save costs the extension cables don't wire the ID pins (#4), which is needed to signal OTG status.
That being said, all that a Y cable does is provide external power to the VCC/gnd wires. Easy enough to turn a right angled OTG cable into a Y cable. I'm just out $10 for my experimentation.
