Hi all,
I have started the long process to "hopefully" de-brick my G1. I have a question though, I have the HTC ExtUSB-3.5mm converter, so I know I can use it for the serial cable, the problem is I don't know which wire connects to which pin, could someone possibly help me with that ?
Fwiw, here's a low-res photo of my cable : (Can't put outside link since this is my first post)

I can provide a higher-res version later if needed, I just don't have the good camera right now.
OK, I was able to identify the wires by breaking the 3.5mm jack open. There's a small labeled board inside. I'll post pictures soon when I have the camera.

Hi everyone, Ok like many others on here I want to connect my mogul to my car stereo. I picked up a 2.5mm(M) to 3.5mm(F) L adapter and figured I could use the HTC provided Y-adapter that has the 2.5mm(F). After trying the setup I noticed it only functioned if I left part of the L adapter sticking out (photo attached).
Which of course led me to believe it has something to do with the built in mic function on the HTC adapter. I then came on the forum and saw everyone having the same issue and recommeding bending pins on after market adapters especially if they are running custom roms (im on dcd 4.1.2).
I have attached a photo to show that I do get sound when I have the adapter partially pulled out. What I wanted to know if there was a way to modify the HTC wire in order to get that adapter to function correctly?
I saw that gator2k83 was nice enough to snap shots of the wires without the insert for the 2.5mm jack here.

It would be great if I could get a picture of what the inside of 2.5mm female socket looks like.
Still don't get why the L adapter doesn't work. Is HTC wiring there 2.5mm headset different then other manufacturers?
Wow so no one can comment on why or how to make this work?
Does anyone know why for example the semons adapter 2-in-1 needs to have its pin modified if you are using a newer rom?
No need to modify anything. You just need to pick up a different 2.5mm to 3.5mm adapter that's made specifically for cellphones. I picked one up a while back at Radio Shack. I forget how much, but I don't think it was expensive. The main difference between the two adapters is that the cellphone one has three bands instead of two, one for the microphone part of the phone jack and the other two are for the L and R channels. Your adapter is only contacting the microphone and L channels which is why you are having this problem. Try the other adapter and you'll find it works great.
TGabriele thanks for the reply! So the cellphone specially made has 3 bands, ahhh now that makes sense. Thats why sticking it in partially makes it work because the 3rd band isn't making contact.
Cool I appreciate the reply
Hi, hope someone can check.
Is it supposed to be a "block" or separator between the pins in the USB contact on the tytn2 ? or is it just "stand alone" out from the device ?
like
pin 1-4
separator/block
pin 5-11
?
pinout
I think this might help:

i found out, someone sendt me a picture from the usb contact.
seems i'm missing a plastic "block"/"separator" in the center of the contact.
I only have the pins sticking out from the device.
i've seen a DIY guide to change here on XDA, just need to find it again
I've searched the HD2 accessories forum and found some inklings of the question I'm asking, but none that quite hit at the heart of the matter. So, my question is this:
Does the HD2 (TMO US) send line audio out through the micro-USB port? I would assume it does, since the dock HTC sells for the HD2 has a 3.5mm jack in back, and it only plugs into the phone via micro-USB.
And my follow-on question would be, if the HD2 does indeed have line audio in the micro-USB port, does anyone know of an actual splitter accessory that splits out line audio and USB charging? I saw this device at AndroidCentral.com's store (sorry, my new account doesn't allow external links) (htc-3-in-1-usb-adapter/5A18A3571.htm) in another thread. But since it's mini-USB and HTC claims it only works for the phones specified, does that mean a gender changer (Daydeal.com, Product ID 31355) wouldn't work with it? Thanks for any info/experiences you folks have!
No one has any info for me?
I browsed around to see if i found anything on this also but i don't think it's possible since it's not a A/V port of any sort. as far as your second Q: The splitter would only be that; something to add additional port's on the device. ie: Since it's connected thru the Micro-sub and the splitter has a mini(assuming)-usb port, it can therefore be charged, Also add's an extra audio jack. (just examples)
Someone correct me if I'm wrong.
Thanks for the response. It may be that the HD2 by itself may not have line audio or any video out signal tied to the micro-USB port, but just the fact that that splitter exists for earlier HTC phones' mini-USB ports gives me hope that the line audio pin out is there. I mean, I'm not an electronics wiz by any stretch, but I think mini and micro USB only require 2 pins for power, right? And there's at least 4 pins there on a micro port.
The older HTC phones used the mini-USB compatible extUSB interface-where the top portion of the connector did the duty as the USB interface and the bottom portion of the connector was the audio interface. Between everyone hating to have a dongle to the emergence of microUSB as the industry standard put extUSB on the road to extinction.

Thanks for that. Makes sense, since they decided (for some stupid reason) to not add a 3.5 mm headphone jack to those phones. But what doesn't make sense is how they can give these newer phones great hardware, and tout their multimedia capabilities, and yet not add a functionality that Apple has had built in since their first iPhone. That's the main reason I still use it: because I don't want to carry two devices around.
Any workarounds for a voip app and microphone for a rooted book color?
the cool guys that know what they are doing are working on bluetooth, that seems to be the best bet to getting a microphone working with NC, cross your fingers!
what about a wired headset with a built in mic. does the nook have the connections to support this?
I think the two best options right now for voice applications are probably the Bluetooth and the slight possibility that the micro-USB port on the Nook seems to have quite a few extra pins on it, which may have left B&N open to a proprietary connector that would allow for additional device connectivity via the micro-USB port.
I've purchased a number of micro-USB adapters in order to plug various devices into the micro-USB port of the NC, with zero success (keyboards, USB headsets, mice, etc). Clearly that port isn't currently operating in that manner, and I'm sure there's a tech savy person that could drop in and give us a simple answer to why this is.
I was also curious about the headphone port possibly have mic capabilities, and was about to purchase a single post headset to test the theory, but then I took a (very unscientific) look at the headphones jack, and it would appear that there aren't enough ring connectors inside it to support an additional channel. Obviously the guys doing the tear-down would know far more about this than myself.
We'll see what turns up over the coming months.
Found this teardown post with spec list and it says that there is no mic input in the headphone jack. I know I read another teardown post which I cannot find that indicated the same thing. I agree that our best bet may be getting the bluetooth working.

Can you detail what sort of adapters you tried? Have you tried a gender changer (type a-a female-female) on the end of the nook cord attached to a keyboard?
Someone correct me if I am wrong but, in order for the usb to do something other than just charge and connect to the PC from the usb, you would have to activate USB host, which is not turned on in stock. Hence no of the fancy toys will work. There are a lot of funky pins on the connector so it may have to be some funky adapter, assuming you get usb host running. There are a lot of hackery potential, but until that project is completed, the wait for bluetooth continues.
Go Occip! (the guy hacking the bluetooth.)

This is what I've been thinking about. I don't have the ability to figure out how to activate the USB Host function, but I read several posts about how it worked on N1, D1, and Hero.
The thing I want to try is using a micro USB to 3.5mm minijack cable like those that came with the G1. It's the only thing I could think of that could logically be supported by the default system since it was necessary in 1.5 on that device.
I don't think anyone is using VOIP yet, but you may be very interested in this thread:
http://forum.xda-developers.com/showthread.php?t=989637
I'm running the CM7 image via SD card from that thread, and the Bluetooth works, and I can connect to my phone and my headset. Several people can connect to their standalone GPS units. Worth watching.
Anyone know if the micro USB port is even powered?
On a lot of phones, the USB connectors aren't powered by the device (like my HD2), so you have to hack together a proper setup that supplies power.
Hi! The unit is listed at Autopumpkin, but I can`t make external links yet, need 10 posts.. Search for SKU: CN03-03101B-US-A to find it.
I want to use it in my 2007 Skoda Octavia, and according to Autopumpkin it should fit (I sent pictures..) The big black power and speaker connector seems to be the same as the original unit, which is a Blaupunkt Nexus.
I`ve already asked a few questions to Autopumpkin, and got some answers, but there are still a few things that I need to know. I want to replace the original roof antenna with one that has DAB, FM and 3G, like partnumber 6R0035501D. Many to be found on eBay. I think I found the necessary cable for FM, with white female FAKRA connectors in each end. There are two white male FAKRA connectors on the head unit , I guess one is FM, don`t know what the other is. I think the antenna has red FAKRA female connector for 3G, I don`t know what the head unit has? Maybe one of the three SMA female connectors? I can read "Wifi" on one of them, but can`t read the other two. There are also two white multi pin connectors on the head unit that I don`t know what is used for.
I want to get the DAB+ module. FM is shutting down soon here in Norway, and this is the main reason for replacing the original head unit. I can`t see from the picture what antenna connector is on the DAB+ module , maybe SMB female? I think the roof antenna has a black FAKRA female connector for DAB. The antenna also has GPS, but some say it is better to use the enclosed GPS-antenna?
Not sure how the roof-antenna is powered. I can`t see any extra lead for power. If it is phantom powered from the radio I guess this must be done externally, or does the head unit provide phantom power on the antenna connector(s) ?
If anyone has an installation manual, or some other useful information on installation or issues with this head unit it would be great!
