Ghetto full size USB to micro USB cable. - Hardware Hacking General

I was bored so I thought of making a micro USB to USB calble for a flash drive or something.
So would cutting the wire from both cables and individually soldering the correct wires be that straight forward or are there less pins in the micro USB cables?
I could just be a cable from eBay but I thought of learning to solder stuff for future use.

If you want to practice go for it. Just match the colored wires. But for a $1.99 or less.......

I think you want an USB OTG (on the go) cable. If you want to make your own you just need to ground one of the pins so the phone detects the cable correctly. I did mine some time ago

Kindle Fire no USB cable

I just received my KF today in the mail and the package only came with the KF itself and a wall charger. Is it supposed to include a data USB cable?
Nope. There's just the Kindle, charger and the little piece of cardboard telling you to turn it on iirc.
Wow nice, poor choice on Amazon's part. I understand it depends on the Cloud but not everyone is using it. Now I have to buy an aftermarket cable to put anything on it. I'm a bit disappointed.
My Kindle came with a normal USB cable you can remove from the wall part and put into computer...I don't think it would be any different. Just like all chargers from HTC Samsung etc lately

Yeah, I thought the same thing. For now I use my Evo 3D's USB cable, that works.
I'm looking into getting this cable from Newegg.com.
If your buying the usb cable online go to monoprice. They are cheap and there cables are nice.
I do not work for or own mono price but I have bought all my cables from them hdmi and so on.

It does not come with a usb cable, just the device, power cord (ac adapter with a usb micro connected to the end) and a cardboard brief info card... That is it.
As a wifi device, no usb cable is required, though you can use one to save files from your computer.

No, it doesn't come with a usb cable. I've been using dropbox to get files over. Though I have a dozen micro usb cables lying around.

What's the difference between a micro USB to Female USB and OTG cables?

Won't detect my USB stick using a micro USB to usb , is there anything special about OTG cables?

is there a way to ground the cable I have ?
you can gentle cut the plastic off the cable connector and jump or solider pin 4-5 together But doing so will make this cable NO Longer able to charge the device .the pin 4 in the cable is a sense pin that toggles charge/ data mode. YOU will also have to have a usb a female to usb a female adapter . This is because usb storage devices have a usb A Male connector. .
So just buying OTG Cable can save you some hassle . They are only a dollar or so..
If you like to mod this type of thing . By all means do so ..
I wouldn't advise trying this with a HTC cable as they fill the pin section with liquid rubber so one its dried its secure but then very difficult to get back to the contacts

Just buy an OTG cable off of Amazon. They're less than a dollar. And OTG cables pretty much put your device in 'master' mode whereas with regular cables it's in 'slave' mode.
I agree, just buy the proper cable. I buy them from ebay and while it does take 3 weeks to get here, it's only about a buck each.
I've ordered one from amazon, hopefully it works.

Tighter USB cable

As I find the USB cable provided with the charger to be too short, I ordered a cheap 2m cable. This cable is quite tight if I want to push it into the USB port of my Nex4, so I was wondering if it is safe to use; are micro USB ports very vulnerable?

Micro USB is designed in such a way the plug wears out quicker than the socket (as it is easier/cheaper to replace the cable), so a well used plug may be loser than a newer one. Can you remember how tight the original was when you first used it?
If this new cable is tighter than the original I would be inclined to say do not use it. A cheap one is probably not made to the correct specifications and if this is the case it could damage the socket in the phone.
Buy cheap buy twice.

Phil
Thanks for your reply. It certainly is tighter than the original was at first, so I guess I won't use it for my phone then. It was only three bucks and most things I bought from China wholesales/warehouses were actually quite good concerning quality, so I don't mind it.

Extra usb ports.

Currently a work in progress but I have soldered a usb hub to the ouya and it works, I am building a custom case with acrylic plastic. I will post more progress as I go.

for anyone else who wants to give it a go these are the soldering points on the back. I am by no means a soldering pro. I was told because I am soldering on the bottom on the board the actual USB port should not be used because it can short circuit the board.. I am not 100% certain about this but for the time being I will stick to using the other 4.
current state. but all 4 ports are working.
saved for post
Jealous!! I haven't tried it yet but I was hoping to use a standard USB splitter, will that not work?
This is basically just splitting the port like a hub. It uses the same leads as the existing. There should be some extra room on the case. Perhaps get a female USB and dremel a hole. Motherboards typically come with extra USB ports that have loose ends and have screw fasteners that attach to a slot vent or case opening. FYI in case someone is thinking about doing this.
I'd say you could just cut a whole and screw in a new port. Probably look halfway professional.
Do Hubs not work? I'm pretty good with a soldering iron, might give this a go just to have my HDD and a Wireless Air mouse connected.

Hubs do work. I am looking to build it all into one housing, I have a kickstarter edition Ouya so I am doing what i can to keep the original case intact. :silly: I have attached a micro sd USB adapter to the hub and it works aswell so i hope to cram that into the case.
That's pretty awesome!! Looking to see the final case setup :thumbup:

will the G2 connect to a 3.0 USB port?

When I connect my G2 to my PC, I get the message about how it will benefit from a 3.0 USB port. As far as I can tell the USB adapter it comes with isn't a 3.0 compatible cord. I was thinking about ordering one from Amazon. What do you guys think?
*UPDATE*
Looking at the connection, a 3.0 micro cable will not connect to this phone. Wonder why I get that message. I'm guessing that this is a misnomer my PC is throwing up.
My guess is this is just a generic warning Windows 7 likes to put out for anything it thinks might be usb 3.0 compatible

No other phone or tablet I have ever used has said this, even some new ones using Snapdraon 600 chipsets. My guess is that the Snapdragon 800 in our phones does in fact feature a USB 3.0 controller for it, but we probably just have the port for a 2.0 cable which is standard.
EDIT: found this:
LG’s G2 is equipped with the Snapdragon 800, a 2.26GHz quad-core Krait CPU paired with the Adreno 330 GPU. It supports USB 3.0, up to 4K video playback and capture, and supports Quick Charge 2.0 for up to 75% faster charging times.

I am seeing the same error. Based on the color of the USB on the supplied cable, it is not a 3.0 cable. However, the device is 3.0.
I am having issues finding a USB 3 to USB micro (not micro B) cable. It would be nice to have when the time comes to start moving ROMs from the desktop to the device :laugh:

Did you see the pic I posted above? A 3.0 micro usb cable has extra pins and it's a different shape. The chipset might have 3.0 architecture, but the port is only 2.0. Maybe on a future model this might com about, but not on this phone.

Yes, I did, and the emoticons in my post were not intentional, as they are supposed to be the letter B.
The cable you posted is not what we are looking for. We need to determine if there is such a cable as a USB 3 to USB micro. This is different than the pictured cable, which is UB 3.0 to USB Micro B.
I do not have my stock cable handy, so I cannot remember if it is USB 3 at all. Is the plastic blue inside the USB side?

I think you're a little confused. You refer to "USB Micro" and "USB Micro B" as if they are different connectors. They are not. Yes, people commonly refer to it as a micro USB connector, but only because they don't know or drop the "B". The LG G2 has a USB 2.0 micro B connector on it. It does not have a USB 3.0 micro B connector on it. The cable pictured earlier in the thread is the proper USB 3.0 A to Micro B cable. Obviously, it won't fit in the LG G2, because the LG G2 does not have a USB 3.0 micro B connector. This does make it very strange that a computer would pop up a message saying that the device would work better on a USB 3.0 port when it doesn't have the necessary physical connector to support USB 3.0 but, well, sometimes technology does strange things.

What is a micro cable that's not a B? You mean a micro A?
The stock charge cable is not 3.0.
Can't you just check the transfer speeds?
The Lg G2 micro usb is not a Hdmi port, but it still supports it, through a MHL adapter. So maybe it also supports usb 3?
I am wondering if we can disassemble the phone and replace the USB board with a board that has a USB3 port soldered to it. Then of course also cut out the outer case shell to have a bigger hole. Wouldnt look as nice but it sure would be nice getting much faster speeds since both the chipset and storage system are easily capable of so much more.
Also, this is what a USB3 micro-B connector would look like on a phone:
The micro USB port is not MHL incompatible. It uses slimport like the Nexus 4.
Based on the service manual and the physical configuration of the port I believe that this phone has a USB 3.0 port, but we just don't have a cable or adapter yet to access the rear pins. Attached is a sketch I made showing what the port looks like. The service manual on page 468 supports the physical configuration of the port (3 pins on each side of central standard usb 2.0 5pins ). I am hoping the Nexus 5 will have this port and help LG push out the necessary adapter. I hope we can get some official confirmation on this at some point. I would use USB 3.0 for transferring or recording video directly to flash drive. There is also a potential for 4K recording like the Note 3. So big files would be common place while recording a 4K. 4K streaming from a G2 to a ultra HD tv has already been demonstrated at a trade show in August.
So yes, I believe a micro USB 3.0 port could be added, but by no means would it be easy, or look right. Best just hope for an adapter.

The LG G2 definitely does have a USB 3.0 connector, but unfortunately it is a proprietary non-standard connector. See my previous post. I can not find a cable with this strange new connector anywhere.

When they are saying its an A cable or B cable, they are really talking about the what the end connector will be. Think of the A connector as the standard usb connector you connect to your computer or to your wall charger. Then think of the B connector as the tiny usb connector you connect to your cell phone or tablet.
Companies sell A to A usb cables or A to B cables (which is what all cell phones use). A simple wiki search on usb will help clear things up.

You're saying it is USB3 compatible, then is this why the plug feels very tight to fit into the connection port? Sometimes it even makes a bit of a cracking sound, as if its not connecting properly, before finally fitting properly.
Looking into the connector, it does look a bit different from my Razrs connector.

That is probably for the most part because it new, but can't say for sure. My Google Nexus was getting quite loose, and I know it was tight in the beginning. It doesn't have anything to do with the proprietary USB 3.0 connector because if the plug is ever released it will be about twice as long as a standard micro USB 2.0 to reach the extra pins. I still can't figure out anything more about it.
Unfortunately from comparing various tear down of the LG G2 and the FCC teardown pictures of the Nexus 5, the Nexus 5 looks to have a standard micro USB 2.0. Definitely not as wide as a standard USB 3.0 and not as deep as the LG G2 proprietary USB 3.0 connector.

Still, there's something off about the charger on the G2. It doesn't match my Razr one, but the Razr plug fits in the G2. The other way around works, but is very, very tight.
Where did you find the breakdown of the G2? I've been looking but didn't find anything.

The service manual is at the following post, but only has schematics. Anything you find that I missed please let me know. The last page of the manual would have the detail we need, but it is only a draft and it is missing.

Am I the only one that is going crazy trying to figure out where we can find the proprietary plug/connector to fully utilize the USB 3.0 our micro-USB port?
It is also driving me nuts to see if 4K video recording will ever be possibly. I would like to record 4K directly to a USB 3.0 thumb drive.
