I am unable to find a slimport cable with a longer cable than 5-6 inches. Is it possible to extend that small cable using a extension cable?
something like this..

My plan is to use this in my truck with a appradio / arliborator, and I don't want to deal with the short cable. I would be able to hide the slimport adapter / charger piece and have just a cable hanging out.

Yes, as long as all 5 wires are connected, you'll be fine.

I bought a couple of cheap generic USB cables, one a retractable micro USB job and the other a standard USB that splits to both a mini and micro USB at the other end.
Both cables charge my phone just fine, but the phone doesn't register either cable as a data connection and no notification comes up.
Is the micro USB cable that comes with the phone industry standard, and if so does this mean that my generic cables are likely to be just off spec enough in some way that the phone doesn't register them?
Strange thing is that the mini USB end of the split cable seem to work on other things like cameras and other phones. I'm confuzzled.
when plugging in cable did you activate usb mount in the notification bar
i bought a mini to micro converter as I still have quite a few devices that need mini and thought I could save on convenience by just carrying round the adapter and plugging into existing computer cables and chargers I have around the house, car and work - Same thing with that power only, no data.
Got it from ebay some of the listings on there state "power only", still dont understand why, it cant be much more expensive to wire all 4 pins. As micro is becoming the standard.....

That's the problem, I plug the cable into the N1, but don't get a notification, no tone, nothing to suggest that the phone sees the cable as a data cable at all.
I'm guessing that if the phone doesn't think it is a data cable there is no way to persuade it otherwise.
There's essentially 2 types of cables: Charge-only or Sync & Charge. This is true for the adapters as well.
It seems you folks mistakenly bought the Charge-only cable/adapter.
After some research, I found this cable (it's blackberry branded, but works 100% with my N1 for Sync and Charge):
http://www.amazon.com/gp/product/B001UC9NOQ/ref=oss_product
It's cheap ($3 shipped), it's made by a trusted brand (Blackberry) and the actual cable is rather thickly insulated so it's durable too.
Read the user reviews, especially the guy with the high helpful votes count, for more details about charge-only and sync-n-charge cables.
Just tried both cables on a Nokia E623, and they both worked fine first time, charging and data.
Now it' looking like there is something slightly odd (or perfectly on spec) about the female Micro USB plug on the N1. Perhaps they are just made to only accept male plugs that exactly meet standard specs, and if a plug is out slightly in say it's contact positions or sizes the N1 won't detect it.
Anyone got any ideas?

Soooo I recently stumbled across this thread http://forum.xda-developers.com/showthread.php?t=744636&page=3
that states that if you short pins 4 & 5 on a micro USB connector and plug it into an HTC Desire, the phone will automatically go into car dock mode. as luck would have it, I happen to know that this is the same method that is used to trigger USB OTG on devices that support it. The wheels in my brain began to turn... $7 and a few days later I came up with this:
MICRO USB HOST ADAPTER + A BIZARRE A TO A USB CABLE = A CHARGING/DATA CABLE THAT TRIGGERS CAR DOCK MODE!
I have tested this on my G2 using Virtuous G-Lite 2.0.1 and it works perfectly, but YMMV.
I got the USB host adapter here
http://www.amazon.com/Micro-B-Adapt...3?s=electronics&ie=UTF8&qid=1328093895&sr=1-3
and the A to A USB cable here
http://www.amazon.com/StarTech-com-...3?s=electronics&ie=UTF8&qid=1328094123&sr=1-3
Just in case you haven't already figured it out you just connect the female end of the OTG adapter to either one of the male ends on the A to A cable, then use the cable as you would any other charging/data cable in your car. the only difference is that now your device will automatically switch into car dock mode when you plug it in! you could also connect this cable to a dock that has a female micro USB connector on the back (like the G2 OEM desktop dock here http://forum.xda-developers.com/showthread.php?t=1473718) and create your own car dock!
an extra word of warning, DO NOT USE THE A TO A CABLE ON ITS OWN FOR ANYTHING! this is a non-standard conforming cable that would damage any two USB devices that you attempted to connect with it. I have no idea what it's intended use is on it's own, but don't think that it is the same thing as a USB data transfer cable (transfer cables have a chip inside the cable that makes the two connected USB host devices see each other as USB slave devices. this A to A cable is just a copper wire)
Nice, I didn't know people wanted this. I got a premade cable. Off ebay that triggered car mode no mods needed and it was a buck. Lol

Any idea about standard dock mode? I know the official tmobile dock auto opens a desk clock.

My guess would be that the cable was not intended to trigger car dock mode, it was just poorly made. a really bad soldering job on the pins would short pins 4 & 5 and do the same thing. Other people have reported this same behavior when they buy low end cables or get water in their micro usb ports.
I tried this and it seams to work but all it does its launch tunein radio, any idea how to change it to other apps such as torque? Thanks
The short thing does work. I my self stumbled on to it while repearing a aftermarked charger .. I opened up the mini usb side and it had a resistor on jumping pin 5( - ) to pin 4 . With the resistor on it charches with the resistor bypassed and just jumped to pin 4 it goes in to car dock mode. Also my friend got a samsung infuse and came with a hdmi dongle usb, so out of curiosity hooked it up to my g2 and it whent to car dock mode

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.
Thought I would share my experience so no one else repeats this. I bought a micro usb ethernet device so I can hardwire my nexus player. Connected it to nexus player and it did not work. The ethernet device had an extra power cable for it. Thinking it may need more power, I foolishly connected power cable. Now nexus player doesn't even turn on (powerlight off). I'm afraid I may have shorted the motherboard. I was able to open up nexus player using guitar pick....but don't even know what to do. Spent alot of time tinkering with it too. So sad as I am now left with an oversized hockey puck Lesson learned.
Look for black marks or brown you can also take a multimeter and check components you would want to check any smd fuses first then trace back from the USB plug. I don't imagine that killing the whole thing. Does it respond at all?

Did not see any black or brown marks. Unfortunately it does not turn on at all. I'm getting desperate and am thinking of buying a new 12v 1.5 amp adapter. Do you think that may work? Thanks for your input.

I don't think so if hypothetically the Ethernet adaptor delivered voltage to the usb port on the nexus player and now with just hdmi and power plugged in it wont turn on i doubt a new ac adapter will fix anything.
You can check your current adaptor if it is broken by using a multi-meter to see if it is providing 12v.
Can you link the Ethernet adaptor you tried to use? And what ac adaptor you plugged into it.
I can think of a few things that are not what you think they are that have ac adapter sockets. But i cant think of a single Ethernet to usb adapter that takes 12v all the ones i know would be a 5v adapter at most with more running off usb power...
I would look for a replacement nexus player not just the ac adaptor... Check target or walmart first they dropped them down to 20-40 when they got discontinued i wish i had picked up a second one now... i got 2 of the game controllers one for 29 one for 10...

Yeah it is not the ac adapter. I tried an equivalent 12v 1.5amp and it still didn't turn on. When plugged in if I put my ear next to nexus player....I do hear a faint hissing sound, so there is some activity going on. I went out and bought a multi-meter and did what you suggested to check components tracing back to usb. This is all new stuff to me but I found that there was 0 reading on a tiny black rectangular module that has P15 on it. I'm assuming that is the smd fuse. Not even sure where to buy a replacement one. Tried to procure one from old computer board but was unsuccessful. Will search some more online on where to buy one and learn how to solder.
The ethernet I bought was http://www.ebay.com/itm/White-Micro...851881?hash=item567e4840e9:g:QEkAAOSwvt1WRYAO I wasn't thinking and plugged a 12v 1amp into it.
Only nexus player I see being sold is on ebay. I'm being persistent on reviving this one only because I spent alot of time on it already and am stubborn....lol But I will give up when I replace the P15 module and it still doesn't work. If nothing else at least I'm learning...so thank you.
Yes the little thing labled p15 is a fuse im about 80% i think p5 is also a fuse... you should get 0 resistance on them and they should be able to pass current switch the meter to Continuity mode and if the 2 probes are connected it should make a noise put them on either side of the fuses if they dont pass current they are likely blown as for replacements dangerous method would be to replace them with a wire otherwise they should be around .50 cents each from what i could find they are self resetting type so they should reset once any residual voltage is gone.

Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .
I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working
So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed
Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?
