Mini USB extension cable?

I've bought one of the adaptors to allow normal headphones to be plugged into my XDA Orbit. What I'd like to do is plug a mini USB extension into the XDA then on the other end plug the adaptor in. Ideally it would be 2m long and obviously be male - female. The main reason is that my adaptor lets me charge my XDA up aswell and I don't want lots of cables in front of me. So i'll plug the extension in and run it into my glove compartment, were I'll plug in my fm transmitter and car charger.
Hope this makes sense, i've spent ages googling to try and find one but i've had no luck, any ideas?

I was also searching for one of these and failed. Post back here if you succeed.

Mini-USB extension cable
I found a single source at
http://www.pc-mobile.net/gugf.htm. It's item number CMUE about half way down the page.
I also found some folks who seem to be prepared to make almost anything at http://www.cypressindustries.com/contact/index.html
Best regards,

Mini USB extension cable
I had the same problems finding a mini usb extension. Then e-bay came to the rescue! This guy
http://myworld.ebay.co.uk/techno_toys/
has just what you need, a 1m long mini usb extension cable for less than £10.00 !
Cheaper and faster than waiting for it to arrive from Hong-Kong
Bill Kelly

Thanks all, google a mini usb extender and this was the first thing that came up. Can't believe these cables are so rare!
FYI my supplier was Keven from Techno Toys on ebay UK http://search.ebay.co.uk/_W0QQsassZtechno_toys

those links you posted don't have USB mini female to USB mini male.
I only need it to be 3 inches.
also, would that 3 in 1 work for my wizard?
Thanks!

This is a link to the current listing (as of 11 Feb 08):
mini usb extansion cable on e-bay
3 were listed, but 2 have already gone. They are 1.2m long too, not the 30cm that you need, but maybe you can cut/re-solder it? They are pretty rare though, so not sure I would risk it!

These wont carry the audio though. They are only 5 pin and carry data only. Ive got one of these cables and the 3 in 1 adaptor. The adaptor is extusb and has 11 pins, and this cable is regular usb with only 5 pins. Not only that, they dont actually fit together as a male extusb is a slightly different shape to the female regular miniusb. Obviously Female Extusb to male miniusb would work, but this cable is the wrong way round for that.

made my own
I was also looking for one to use in my car. Couldn't find any so I made one. Used a vga cable, cut the htc usb charger/2.5 headphone splitter that came with my touch, and soldered the cables together. I'll post pics tomorrow if i get a chance. Btw, i got lucky, because while trying to solder one of the last cables, the yellow cable that connects to the end of the 2.5 headphone jack came off. Luckily, it wasn't the cable that was for left or right channel.

I couldnt find an 11 core cable small enough to look good. VGA cable isnt too thick though... tempting.

Nice, I wish i had soldering skills. everytime i try to solder, the solder never bonds.
I tried heating up the wirers, but the solder always bonds to the tip or combine with the solder coil again.

OK, sorry, I had used it OK with my Motorola phone, and that did the audio OK. Didn't realise there were more pins in the PDA cable.

11 pin extension cable
how many wires are needed for power and Stereo?
I am Guessing 1 for right, 1 for left, 1 for Power, and for ground. I am asking because I want to make my own, but I do not want a big diameter cable.
I have the 3 in 1 splitter, so it has everything I need except for length. Is a 4 wire cable all it really needs?
Anyone?...

Here is another source for Mini USB Extension
Man are these cables ever hard to find. I have been looking for such a cable for a long time since I recently found this other guy on ebay. He has 2m (6ft) and 3m (9ft) versions, all USB 2.0 compatible: kabelbaron on ebay I think he ships worldwide, too...
(I think you can also get to his recent items through http://www.kabelbaron.de).

They look like standard 5 pin extensions to me.
People in this thread are looking for extUSB extenders that have 11pins.

What works for me is to melt a tiny bit of solder on the tip, then touch that melted solder to the wires. It will transfer heat to the wires and you can add more solder from another angle. Wipe the tip on a wet sponge after every use. This leaves a thin layer of clean solder on the tip. If you let the tip go uncleaned for too long it turns totally black and conducts heat poorly. If you buy tip cleaner you can sometimes get the black off.
Also, if you have tiny things to connect and little space to work, put a bit of solder on both things first, then touch them together and the heat will transfer into both of them, melting them together. Keeping them steady after you pull the tip away is key to a strong join. If they're trying to pull apart as the solder cools, the solder will look more dull than shiny and be easy to break.
Also, be absolutely sure you get 63/37 (63% tin, 37% lead) solder instead of lead-free because lead-free doesn't melt till a much higher temperature and that's more likely to damage your electronics. Also, I could barely melt the lead-free solder with three different irons I tried and it was very hard to make it bond to things.
See http://en.wikipedia.org/wiki/Solder for more.

USB power uses a +5V and ground pin on the top row.
Audio uses 3 more pins along the bottom: left, right, and audio ground. There's also two mic pins along the bottom you might want to tap into.
See http://wiki.xda-developers.com/index.php?pagename=ExtUSB

I found a good source for mini usb extensions of all kinds. This site really was the best site for USB and Firewire cables. I got mine today.
Edited: This cables are 5pin, just for data and power not for audio.

[Q] Connector Pinout and raw connector source?

Hey There,
I've seen the pinout for the original Galaxy Tab, does anyone know if this one is the same?
Or if not, anyone know where I could find a pinout for the thing? I might try calling Samsung but I have no idea how much time that will take or if its worth it.
Also, anybody know where to source the raw connectors?
Thanks!

Pinout should be the same since cables and accessories for the 7" work with the 10.1 as well
Here is the thread that has the Tab pinout

Cool, thanks. Now I just need to source that connector...

I would assume some pins are the same but expect many have changed. Since our device has HDMI and USB hosting, there are probably some differences. I would love to be able to make or buy a breakout cable that had everything possible out of it. Right now all the official accessories look to do only one thing at a time.
And I have beef with any accessory that calls themselves a media dock and then doesn't have multimedia outputs. Had to get that out there

Well,
I finally found a source for some connectors:
http://www.kineteka.com/galaxy-tab-connector.aspx
and they have a breakout board:
http://shop.kineteka.com/products/200-samsung-tabbreakout.aspx
I've ordered one of each and will report back.
They clearly say "Galaxy Tab" and not Galaxy Tab 10.1, but if its the same connector, it should be fine.
Though I agree that our unit most likely has more outputs. It would be really nice to figure out what those are! I have a thread at the Samsung Innovator website about it:
http://innovator.samsungmobile.com/...ate=&endDate=&searchTypeForm=&searchTextForm=
But I feel like they won't tell us. I may have to buy the USB host adapter and the HDMI adapters and crack them open.
Anyway, I'll try to figure this out. If anyone else knows, please fill me in!
-Taylor

In the kernel, drivers/accessory/30pin_con.c:
if (acc_adc != false) {
if ((2600 < acc_adc) && (2800 > acc_adc)) {
env_ptr = "ACCESSORY=OTG";
acc->current_accessory = ACCESSORY_OTG;
The acc_adc is the arbitrarily scaled resistor value on the ID pin. I think there might be a place in sysfs to read this out, so you could wire up a potentiometer and work out the real resistor value for this range (2600-2800). You can use ADBWireless to get a shell while you are messing with the connector.
Once in OTG mode, the USB D+/D- pins used by the sync cable should become USB host.

Ah, I was afraid of that, I know plenty of mobile devices work that way. I was really hoping it had two separate ports like some other tablets, so I can use my accessory and the USB host port at the same time. I may have to do some juggling then, grr.
Thanks for getting that info though! I'll try that with my breakout board when it comes in (if they ever ship the damn thing...).

In another post, a guy put 20K ohms between Pin 13 and Pin 15 and got the Tab to go into host mode. Then the following for the other pins
Pin 1 (GND)> Black
Pin 3 (D+) > Green
Pin 4 (D-) > White
Pin 6 (+5v)> Red
If anyone figures out how to get HDMI out, please share.

Desk dock for debugging?

I was disappointed to find the Samsung dock doesn't offer USB connection.
Anyway does anyone know of a GOOD desktop dock that I can debug adb through?
Looking for something made specifically for the nexus so there's no wobble once the USB is connected...

You might have a look at sinjimoru docks:http://www.sinjimoru.com
Pretty nice and simple docks, usb connected and not that expensive.

If you don't mind "disfiguring" the dock a bit, you can use a Dremel tool to grind a notch in the left side of the dock to allow access to the USB port. I did this to my dock with no problem. I was hoping to use USB OTG and charge at the same time via the pogo pins. It doesn't work, since the two functions are mutually exclusive with the stock ROM, at least.

You didn't specify GSM or LTE, but I have two of these docks and they work great: http://www.amazon.com/RND-Power-Sol...5K9C/ref=sr_1_1?ie=UTF8&qid=1337015416&sr=8-1

Hi, I would like to achieve this too, could you please give some more details about the process?

No point destroying your dock, only one of these(pogo charging/usb connection) can happen at any point of time due to hardware limitations.

Using USB as audio output?

Hi everyone
I know this has been posted in another forums, but without any or good answer.
What i want it's to make an USB to 3.5 Jack adapter to use with my Galaxy S2.
Anyone can help me with this? I'm curretly using RR and as far i could read it says it doesn't have the Dock mode. So, this will be possible?
Thanks for the help!

pinouts
http://forum.xda-developers.com/showthread.php?t=1321491
These are the pinouts for the micro USB with instructions on how to make the cable. You can ignore the power input unless you are trying to make a nifty car dock...
Sorry I don't know about dock mode, but different ROMS behave way differently on the USB, so I would try ROMs and kernels until it works. I think ICS is better for USB connecting things.
Good luck.

Tried on RR 2.4 with Samsung Desktop Dock using line out from the dock to speakers - doesn't work.
Was hopeful because I saw Dock audio settings under System Settings --> Dock, but Audio options was greyed out. Likely to be an issue with CM9 and Siyah kernals.

i've gone about it in a different way. i'm fitting a usb port to a blanking cover in my dash board and taking a aux line in from my head unit and power from behind the dash (ignition fed). as i have an s3 i need 1 amp for the power side of things. all parts have come from ebay for about £11.00 about $18.00

Nice work Post pics/detailed instructions. I'm sure other people will be very interested.

Combined audio/charging cable for Note 10.1 N8010?

Hello all, I've been searching this one now for a few hours and wondering if such a cable exists, surely it must do?
I am making a custom car dock for my Note 10.1 N8010 (2012 version) and would like a cable that allows it to charge (at the full 2 amps, I've got a car charger, the cable just needs a USB A plug to go into it) and also output audio through the dock connector. An OTG port for plugging in external storage would also be nice but not essential. Does such a cable exist? I don't mind if the audio side is RCA or 3.5mm jack, I can convert it to what I need.
The closest I could find is this one on Alibaba: http://www.alibaba.com/product-detail/USB-AV-Audio-Video-TV-Out_60008986653.html but it says it's only compatible with the Tab 7" and has a minimum order quantity of 20 units, I only need one! There's so many cables out there for newer models but I can't seem to find one at all for the 2012 version.
Another possible solution might be something like this: http://www.amazon.com/Zek-Samsung-Galaxy-Reader-Adapter/dp/B00DZA6F74 , which, although powered, doesn't specifically say that it could charge the tablet (says it's to power connected accessories). Does anyone have any experience with something like this?
Can anyone else advise on this? As a last resort I could cannibalise one of the many cheap docks on ebay but I'd much rather use a cable for a neater result. Ideally my budget would be under £10 but I'd consider up to £25 as an absolute maximum.

I own it & the external power is not for charging.
It's for powering a high powered USB devices such as USB HDD.

Thanks for letting me know. Makes sense, I'm just surprised that no cable exists for charging and audio output at the same time along with OTG, I'm sure it must be possible somehow. I guess I'm just asking it to do too much, I may go for the video output cable from Alibaba in that case then and do without the OTG/USB functions.

There's a dock that has charging and a seperate audio (analog) output. I have two of them. The audio only works with stock Samsung roms though. With CM there's no audio out.
this is the one: http://www.ebay.com/itm/Samsung-Des...ng-Galaxy-Note-10-1-N8000-N8010-/370816243987
