[Q] DIY USB Cable? - Asus Transformer TF700

Does any one know what the pinout/components of the USB kit are? I want usb otg but I would rather have a dock cable with a usb female connection rather than the bulky oem usb kit. I'm thinking of just buying a dock cable and a female usb connector. I am assuming that there is some resistor there that signifies the USB Cable. Any ideas?

Glad someone else is itching for home made cables too. Already got the iron on standby ready to go. After a bunch of link hopping and thread reading, here's the most useful info I've found so far...

I looked at it but I didn't see anything useful. I could use info on the internals of the USB kit. Was there something I missed?
(I awaiting my new multimeter and then I'll order a new soldering iron)

Once all the needed pins are IDed it should be easy to order the plugs and make your own cables for pennies on the dollar or start work on an OTG or other cables.

[Q] 40 pin connector pinout and mating connector anyone?

I believe the 40 pin connector has everything we could use including HDMI, USB, charging, and probably more.
Does anyone know the pinout and the mating connector? I want to make an adapter that would make the HDelight WHDI transmitter work with the tablet directly without the dock. It needs power from USB, in addition to HDMI. I am guessing both are in the 40 pin connector.
BUMP
Since the TF101 has been out a while, so hoping someone has some info on this?

I have got the 40pin connector but don't know what can i do with it.. ummm.. I mean, What's the accessories will be hot? A cable integrated HDMI,USB3.0 and WLAN? Dose TF101 has a WLAN? I haven't open my TF to see..

If you can make a bunch of Power Adapters for it...that's be great. I've been trying to find the 40pin connector for a while now.
I don't think people need HDMI out on the cable, b/c that's built-in in the form of a mini-HDMI cable. I think most people would want a way to hook up USB devices to it. A 40pin to USB hub (3-4 ports) would be really nice.
I think the power adapter for a reasonable price with a nice long cable would be an excellent start. 15V, 1.2A switching power supplies are cheap in China + wiring it up to the connector for $20-$25, I think you'd have no trouble selling those. As a bonus, if the adapter ALSO could take a 12V car adapter as input and not just 110-220V AC...well that's an easy sell right there!
Thanks!

Docking
Verkion,
I think using a USB car charger with the USB cable would work, wouldn't it? I haven't tried it though.
Anyway, if anyone gets hold of any info on the docking connector, pls let me know. I'll make it worth it!

nope, standard car chargers are 5v usb spec.... the TF only starts to charge at 11v or so, IIRC.

Can you divulge your source for the connector?? I can make a GRIP of specialized cables connectors and docks. I'll post all tech info on comm from the 40 pin.
I have found a 40 pin connector but can't post a link as a new member. I think the offset between the two rows of pins is incorrect but may help with someone else finding the correct one. I'll contact the admin to see if I can post the link.
You may be able to find it from web 'alwaysinnovating' wiki/index.php/40-pin_connector

Here's the link you're trying to share:

(note: I've done nothing to confirm whether this is the right connector or in any way related to it myself, I'm just sharing the link to save somebody else the hassle of googling.)
That 40 pin connector doesn't have +15V lines. Hence the electrical layout might be a bit different than what's listed.
Thanks for posting the link. As AnTrans said, there is a good chance the pin out assignment listed on that site is NOT what the Asus uses but may point towards finding the correct connector.

The important part is it looks like he found the connector itself, and it seems to be available from some major US distributors. The rest is a matter of reverse engineering

Edited: Yes you are right.
From the data sheet, also 2129261-1 will fit. The 3.3mm thick will fit into a receptacle that is 3.8mm thick. I think the pins are okay (might be wrong).
In *addition* to your choice, try this:

See the mfr's page here , particularly the "View Product Drawing" link. The dimensions of the plug are (excl. the latches) 18.5 x 3.1 x 7mm (7mm being the minimum start of the overmold). I don't have calipers on me right now, but the pins are on .3mm staggered centers, so the distance from an edge of pin 1 to the same edge of pin 40 is 11.7mm. I still think this looks like a winner.

Okay, I agree with you. I was wrong, looking at 3.8mm on the receptacle.
Both your part and my part are the correct outer dimensions. The differences only depend on what type of mount - board or cable.
Looking inside my ASUS cable with mag-glass the pins are staggered.

[Q] Asus Transformer full size USB Challenge

One of the very few downsides to the Asus transformer is the lack of a full-sized USB port on the tablet itself. You can always purchase a dock and Asus has said that they will be selling a miniUSB >USB dongle. However, neither of these solutions is really the same as having a slot within the tablet.
I figured the folks at XDA wouldn't stand for this!
Here is my challenge. Add a full USB slot to the tablet and post instructions.
Here is how I could see this going down:
1) Someone with more hardware know-how, open up your transformer and find a physical spot in which one could place a full female USB connector with a small mounting bracket.
I haven't seen a hardware teardown yet probably due to lack of stock.
2) Figure out wiring from a full USB slot to controller. Perhaps directly splicing with the microUSB cables?
3) Either do it yourself or write up your findings and let the community try.
I think with a small dremmel tool and some pieces from radioshack we could make a pretty good mod.
What do you guys think?
I'd be interested to see someone do this, but I think 99.99% of the population would be too afraid to take a dremel to their TF considering it is about 6 mm in width at the edges. It would have to be a pretty tiny dremel. That's not considering the risk of opening it up. Then, finding the right location to solder the USB port to on the circuit board.
I think I'll wait for the dongle
The easiest would be a dock connector to USB dongle. That way, it doesn't require opening anything, just scoping the dock and how that works.
Just wait for the official solution that's my advice
For what it's worth, I bought a usb 3.0 F-F adaptor and attached it to the power cable. I then plugged in a usb memory stick. There was some activity and drivers were loaded on the Transformer, but the memory stick was not recognized.
Anyone else have any luck with this?

[Q] Asus Proprietary plug to USB converter? or anthing similar out there?

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)...

[Q] USB host mode, specifically via Nebtop

So, I purchases a USB OTG cable in an attempt to try and expand the functionality of Webtop while using Nebtop. I've been unable to get any response from the phone when I plug in this cable. I've tried my wireless Logitech mouse and keyboard that worked off the bat with my TF101 using the Unifying remote they came with as well as an external TB drive.
Has anyone else had any experience with this? It seems logical that the phone supports host mode since the actual dock has 3 full sized USB ports.
All the information pertaining to this sort of thing I've come up with seems extremely phone specific but if there's a simple solution I'm missing thanks all the more.

The problem actually lies in the usb port of the phone itself. The dock was designed for this purpose, and the dock app handles most that for you, the one thing that the dock is able to do that a straight USB cable can't do, is provide enough "bus" power to use a mouse or even a USB stick directly from the phone. If you want to use a Mouse you will need to get a dock. I got mine directly from wireless.att.com, and it was only $49.00 back in Nov. when I got it. It works VERY well with webtop.
P.S. Motorola is very famous for doing things like this to force you into a dock, or to lock out certain features that everyone really wants to use.
I made my own dock by using a powered usb hub I had sitting around (it was actually the one that came with Rock Band for my Xbox 360). I did have to modify it slightly so that the 1 pin was powered from the 5V (a simple shunt from the 5V inner pin of the power supply solder joint to the solder joint of the 1 pin worked fine--although it might be wise to insert an inline fuse since it also charges your phone while plugged in).
Otherwise, the only other thing needed is coming in the form of your otg adapter that should short the 5 pin (common) with your 4 pin (ID). I did this by cracking open an extra micro usb cable and soldering a wire between the two.
So, my setup was like this:
1. Modified usb cable to short the 4 & 5 pins to let the phone know to go into host
2. Use a female A-female A usb coupler to join the usb cable to the powered hub (I got mine here from Monoprice
3. Get 5V to the 1 pin in the usb hub to provide power to your phone and for whatever is plugged into the hub.
With this, I was easily able to run a usb mouse and a wireless keyboard that had a usb dongle. Paired with a micro hdmi cable to hdmi-dvi adapter, I am able to use my office monitor and the webtop linux. I honestly haven't really used it much yet (if I found it really useful, I probably would have just paid for the dock).
The obvious easy way is to just get the dock. However, I really like being able to do this on my own and since I had this stuff already laying around. Also, the cheap prices from monoprice (I actually made $4 off of the purchase from a PayPal bill-me-later promotion).
So, you should be able to get it to work if you get power to the bus on your usb (but again, it might be safe to pass an appropriate fast-acting fuse, ferrite core, or something to protect from surges). I haven't had issue yet, but I also don't use it often...yet .
It sounds like a bit of yes and a bit of no. The OTG cable I got is microUSB to female full USB, am I going to need to modify this cable as you've described by crossing the 4th and 5th pins?
I'm thinking about ordering this "7 Port USB Squid Hub" since it has the 5v power adapter, do you think it might work?
Just one more question and thanks for all the help but should I not see any response from the phone when I plug in the cable? I read through some of the reviews for cheap cables on Amazon and apparently sometimes they're just useless.

The OTG cable have should work. The OTG cable, to my knowledge, should already have pins 4 & 5 shorted together. I'm not completely certain, but if it's designed as an OTG, it would probably already have that done. If you have an ohmmeter/multimeter, you could try to check (it's hard to isolate the small pins, but you can try). If it's already going to the USB female (type A), you will then be able to directly attach your hub when you get it (without the need of the coupler I had to get).
When I used mine, there was no notification that said "Hey, I'm in USB Host Mode!". However, if you successfully have a mouse attached, you'll see a mouse cursor arrow on your screen.
Have fun with it and if you can't get it to work, let me know and I'll try to explain with even more detail (perhaps with some pretty pictures) of what I did. I more or less went off of what I could glean from reading what others did.
It works great! Also, it is weird to see the mouse on this little a screen, it seems oversized.
I just plugged everything in and it worked off the bat. I'm using just two items from Amazon I got for under 12 bucks (plus, of course, the keyboard and mouse I already had for my computer). I don' think I can post links to the forums yet but the ASINs for the items if people want to do this on the super cheap are as follows:
B0043TBCDS 7 Port USB Squid Hub, a whopping $5.19
B005N55WHI Micro-B USB OTG Cable... $5.99
I chose these because of their Prime eligibility and also for their form factor so as not to cover the HDMI port, I bet it's not impossible to get these even cheaper.
While this isn't technically a replacement for the dock since I had to root the device and I have to press "Load" in Nebtop if I want to go to Webtop I'm extremely pleased with the results.
I also love that all the soft keys are available. The ones I've discovered are that right button on the mouse as well as Esc are Back, the Home key is Home, clicking the wheel as well as Ctrl, Cmd, Alt and a whole slew of others bring up the Menu, but all I can find is F5 for Search.
On another note, while the phone does charge when hooked up, a practical boon, the screen still times out despite having the "Stay awake" feature checked. This is annonying when the phone is on it's side accross the room and I have to squint to see the cursor and swipe it unlocked sideways as well as click back into Mirror Display.

[Q] Asus USB adapter alternative?

hey everyone, so i have been reading around and there are alot of people talking about the usb extention for the asus transformer.
Here is my thought: what if you used your existing usb charger/data cable and then but a female to female usb adapter on it? this has just been in my mind for a while and i saw that the adapter would cost around 3 instead of 20 for the asus branded one.
has anyone tried this or should i just get the adapter made by asus?
For $3 why not just try it and let us know?
I'm pretty sure this will not work, since the adapter has additional circuits to put the tf in usb otg (on the go) mode, which is the usb host functionality in plain english.
Yo will need an usb 3.0 cable. It won't work with a normal (2.0) one
As alluded to above, 2 different things.
The usb3 cable is an extension, the adapter is a hub (adding usb to the tab).
