[Q] plugging into car stereo usb, not recognised - Thunderbolt Q&A, Help & Troubleshooting

i have a pioneer premier that worked flawlessly with my iphone. it has 2 usb inputs, and aux in. I WANT TO CONNECT VIA USB. Please dont offer advise about bluetooth or headphone jack.
Normally, if i plug the phone into the laptop, i can choose all the options like charge only, mount as disk drive, etc. When i plug the phone into the wall outlet, i do not get any options, it just charges. When i plug it into the car stereo usb, it just charges, and i dont get any options to turn on mount as hard drive.
does anyone know how i can "force" it to mount as a hard drive, or how the phone actually knows its a laptop and an outlet? maybe i can jumper some wires, or something.
thanks

I too would like to know this

No charge when usb connection on car stereo

Hey everyone,
I'm having problems when connecting the thunderbolt to my Sony usb stereo. It asks me what I want to do and I choose charge only but it doesn't charge.
I use to have the Droid X and it worked fine on the stereo.
Anyone having the same problem?
Any hints or tips for this?

Your deck usb port might not provide enough power for the thunderbolt...but might have for the droid x. The usb addon for my pioneer never worked for charging when I had it installed. Just read flash dives, but that's just my two cents on the problem...could be something else.

I know some devices (like my Motorola dumb phone) will not charge over generic USB power (power and ground only), but if you use a USB "Data blocker" (grounded data pins) some of them will charge. This may be the same way... or it could be the whole requires more than just 5V to initiate charge without detecting data (meaning a PC connection).
You could try placing some MP3s on your SD card and tell your radio to "play" the usb drive and set the phone to automatically mount as a drive. That may do it, if not, look into the grounded out USB cable.
I just installed a lighter receptacle behind the stereo and ran up a car charger (not a usb charger) through the back of the dash to the car dock.
I was able to get the phone to charge via the USB port on my kenwood deck, but it was USB power, and discharged faster than it could charge.
It now reports charging AC, and charges normally. Cost $6 at radio shack.
I just tapped into the positive and negative wires that were already going to the original 12v lighter.
I'm actually having a reverse problem. My phone charges in my car stereo's USB slot, but the receiver doesn't recognize it as a USB drive. The phone doesn't even notice there's a USB connection, even though it's charging.
Oh well. It has AUX too so, no problem really.

I have the same problem, but I suspect that's because of that stupid "Verizon Mobile" virtual CD on the phone. I bet that's what your deck sees and can't find any music.
If anyone knows how to get rid of that partition without rooting the phone, I'd like to know.
In my case I have to use the Bluetooth connection. That works, but it doesn't give me the song information on the deck. Might have to revert to an old iPod for our music in the car.

With my old Incredible, my car stereo acted differently. It would see the phone and the phone would ask me to go into disk mode. After a few moments of scanning, the receiver would say "Invalid Media". I was also on CM7 for a little and I was actually able to get the receiver to play music thought it.
It's a Pioneer DVD player.. Unfortunately with the Thunderbolt, it doesn't do any of the abolve. It just says "No Device" and the phone doesn't even do anything except charge. Doesn't ask me to mount.
Okay I found a solution. I believe the problem was the Verizon crap that ran when plugged in. I installed The Perfect Storm Rom and now its charging fine.

[Q] Dual micro USB?

Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.
macc
When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.
macc
The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

[Q] USB Cable type for Sony Tablet - specific details

Hi everyone,
and thanks in advance for any help / advice that you may have for me.
I'll start off with my question, before I unload all of my information. I simply would like to know exactly what type of USB Connection the Sony Tablet has, and therefore, what specific USB Cable I need to buy in order to connect it to my PC running Vista.
I bought a Sony Tablet and have been surprised the lack of information in regards to the USB connectivity of the device. Specifically, the exact 'cable type' required to connect the device to a PC. Everywhere I have read so far, it simply says USB Micro, or USB 2.0 micro. But when I try use the micro USB cable that I currently use with my Xperia Play phone (which works fine for PC transfer with the phone) it's doesn't work at all with the Sony Tablet. It doesn't even register on the PC when I plug the cable into the tablet. Just nothing.
Since then, I have read a lot about USB, and found that there are different types, like 'Mini USB' versus 'Micro USB'. Apparently there is also Micro USB 'A' and Micro USB 'B'. And finally, apparently there is 4 pin micro usb and 5 pin micro usb type.
hope this all makes sense, many thanks guys.
Austab.
This tablet uses micro USB, I'm pretty sure the cable for your Xperia should work fine with the tablet. Perhaps you plugged it in upside down?
Thanks for the reply, I agree with your thought train. If it works with the Xperia, then surely it should work with tablet. I'll try it again after work today, and confirm. Is it actually possible to plug the cable in the wrong way around?
I'll kick myself if I did! Thanks again, cheers.
Austab.
It cannot be plugged in upside down, unless you use extreme force and break it.

But yeah, this cable *should work, if it works with your Xperia Play. In principle there is only one kind of micro-USB cable (well, actually it could have either regular type A *OR micro type A connector at one end, but let's keep it simple. Mini-USB is a different kind and A and B are just connector types.
See this picture with different USB connectors:
http://en.wikipedia.org/wiki/File:Types-usb_new.svg
Your cable should have a regular USB A connector (the one on the top left) at one end and micro-USB B connector at the other end (the one on the bottom right).
Yeah, it should work; I'm using the same USB cable that I use with my Xperia Arc.
For what it's worth, I've been having issues too. Mostly windows fails to find the drivers and install them. I've talked to multiple Sony reps and have tried multiple computers but haven't had any luck. Maybe it's a bad cable but I have had Windows detect the device...just unable to install the plug-n-play drivers.
Systems I've tried it on:
Custom built - Windows 7 with Service Pack 1
Dell - Windows XP Service Pack 3
Sony Vaio Laptop - Windows XP Service Pack 3
I had the same problem on both of tablet P and tablet S. I can tell you, its more about luck than the wrong cable type! At the end, it just works after retrying a few plugs and unplugs.
Hope they can get a fix for this soon.
Hey again guys, I've now tried the cable again with my Sony Tablet, and I'm definitely plugging it in correctly. There's no response whatsoever on the tablet or the PC once I've plugged the cable in.
When using the same cable on my Xperia play, the phone will instantly start charging once I plug the cable in to the PC. However, the PC doesn't actually recognize the phone as a device (i.e. it doesn't show up in windows explorer, or launch the Ericsson Phone Software, as it once did). It charges the phone, but doesn't talk to it, if that makes sense.
So it would seem that some Micro USB cables are good for charging only, but not for data transfer / PC recognition.
I'll buy a different cable tomorrow so will let you know if it works then.
Thanks again for all the replies guys I appreciate it.
cheers again,
Austab
Looks like the cable is faulty then and you have to try another one.
I bet one of data wires is broken, or a data contact inside connector is broken (worn down), because when you connect your Xperia Play it should also be recognized as a device.
Then again, maybe there is something wrong with your computer.
Can you try the same cable on another computer, and see if the device is recognized, before you buy a new cable. Or let them check the cable at the store to see if it really is faulty.
My understanding is you need an OTG USB cable, (On The Go) - this is what you need to connect USB keys and other hard-drives and so therefore I would think external PCs too.
I bought a nokia one for around 5 pounds from amazon, do a search for OTG USB cables,
thanks
Pratish
He wants to connect it to a computer, not connect external devices to it.
So he needs a regular micro-USB cable.
the cable is USB Host finde with this name
People, wtf are you talking?!
He *does not* need USB host (OTG) cable. That's for connecting USB devices, like keyboard, mouse, USB-storage etc., to your tablet.
He wants to connect his tablet to a computer. For that he needs a regular type A USB to type B micro-USB cable.
Hi,
Would seem like op had a charging cable, not data one. As stated, he need a regular data cable with appropriate connectors. OTG has nothing to do with it.

Hi Crazzzik,
so you're saying that there are micro usb cables for charging only, and then there are micro usb cables for data + charging etc? That would explain things perfectly for me, as my cable seems to work for charging devices, but not communicating with a PC (i.e. data transfer).
I'm getting a new cable today - sorted!
Many thanks everyone for your help & advice
Austab
Yes when I got the cable for my sony tablet s, I saw several usb cables that would fit the tablet, but on the package it said specifically "for charging only, not meant for data transfer", so they do make the cabkes just for charging, as a PC tech, I was a little embarrassed that I just found this out this weekend.
Thanks
I also got a microUSB-cable adapter, it works fine with usb driver / joypad and keyboard
but not sure if it's capable for connecting with PC or even for charging
hello all,
I recently bought the usb cable for the tablet they sell at the sony store. The micro usb to female normal usb ( I think you know what im talking about). It is sony tablet specific. The micro usb end of the cable is square instead of tappered at one side. it worked fantastic for plugging in and usb deviced to the tablet, but when I tried to plug it into my galaxy s, it wouldn't fit. just thought those thinking of buying one would appreciate the heads up so its not a shock if they try to use it on any other devices. Im sure you can find that same cable at any well stocked computer shop.
i borrowed a htc wildfire s cable, this works and installs drivers.

PC not recognizing the tablet at all when I plug it in? Anyone seen this?

Hi!
So basically I can charge the tablet with no issue but when I connect it to my pc (or the one at work) it suddenly is no longer being detected (no USB plug in sound).
At home I was able to make it work but it would seem that moving the cable a bit will make it go off so somehow the cable must be bad I think even though physically outside it looks great.
Could that be it?

its very plausible that you could have a bad usb wire. if you wiggle it and get a connection very likely turns to 100% sure. There are different wires for charging and data within the cable. no connection when you plug it via dock either? (just want to rule out on board connector)
I will have to test on the dock but when it connected yesterday, I tried moving the plug around the table area to see if it was there and it never disconnected yet moving from the USB side connected to the PC made it disconnect so it makes it sound like a bad cable for sure...and hopefully

Charging with USB data pins disabled or disabling data connection

Hey guys,
I'm using my tablet in my car and have it connected to a Kenwood radio which has two USB ports. The radio can recognize the android device and changes automatically to USB as an input and then my steering wheel controls don't work anymore.
So as a workaround I bought an USB adapter which only connects the power pins. But with this adapter, the tablet is not charging. The cable itself is working as intended with another phone, so it has to be something special about the tablet.
Does anybody know if there is a way to use a data connection via USB to only give power to the Z2 tablet?
Man, somtimes I'm just an incredible idiot. The Xperia Z2 Tablet has a dedicated charging port at the bottom for which I already have a cable. So, I'm going to use that.
Sometimes the solution is so damn obvious
