I think it came with android 12, the card reader is not recognized when plugged in. I have tried 3 of them. They used to work with my S21 Ultra. When I plug them in to my old P30 Pro, they work fine.
Also, I can't connect to my PC as I used to, now the only way is to use DEX.
USB debugging is on.
Any ideas folks?
You say it won't connect to your PC. I assume that means wired USB connection? And when you refer to Dex, I presume you mean you're using is wireless rather than wired?
Assuming those things, it sounds like you have having issues with USB data lines and the common denominator here is your device. My guess is a faulty USB socket or worse, damage to the board itself.
You don't mention charging issues but that would still work if the power lines are OK. Does the phone fast charge? That uses the data lines to provide extra power. If it doesn't then there is definitely a problem with them.
I would suggest this is a hardware fault and would need opening up and servicing or a replacement board. I cant help you with that though. Sorry.
No problems here with cardreaders or connection with PC or monitor with wired Dex connection (SM-G998B on G998BXXU4CVC2).
Suggest you first check your charging port for dust or debris. Clean with compressed (dry) air or gently with toothpick.
no problem with charging......wall socket or in the car.
I don't use fast charging
My little thumb drive still works...just plugged it in. As suggested, blow some compressed air in the USB port.

If the power lines are unaffected then your phone will still charge. Fast charging works by utilising the data lines to increase the power provided. Turn on fast charging (you can switch it off after) and plug your phone in to a wall socket. Does it fast charge? If not then there is definitely an issue with the data lines. This then confirms why connected USB devices don't work. As others have suggested, clean the port and see if it works. If it still doesn't work then it will need to go for repair. Virtually all Samsungs have a secondary board which holds the USB port and bottom speaker. This can be replaced.

I have a friend who is visting the US (I'm from Canada) and I asked him to pick me up a nook. Not finding clear info in some of the reviews, mainly concerned about charging.
This charges over usb when hooked up to your computer right? Just want to make sure it doesn't use a proprietary cable for charging. I read on the ipad side, that older computers don't give out enough power to charge over usb, is that an issue with the nook?
What adapters/cables does it come with exactly? And is it just a standard mini-sub for the charging?
Also, this has a headset jack correct? I've read no bluetooth, I guess there's no way to get a mic working on this then.
Micro USB, will charge VERY slowly using a computer. Includes a 2amp wall socket and special cable to quick charge (still micro usb, just more pins). Has a headset port but does not come with a headset.
I've only had a few mobile devices. I read the ipad can charge over usb if the mobo supports giving out that extra juice. Some mobo's have a new firmware update to enable this.
The connector is micro-usb but just more pins. Hmm. so if the cable breaks or I misplace it no other micro-usb will charge it?
edit: i read a little more and found that it's 30 pin proprietary cable to speed up charging. I also read the galaxy tab does something similar.
Does anyone know if they use the same pin configuration? probably not, but I can get tab usb cables here.
I know you didn't ask for it but I'll tell you anyway
In case you are worrying about registering your device (mandatory at initial setup).
I'm NOT in the US and it worked fine.
Good to know. Thanks.
But I'm more concerned about charging it and relying solely on their cables.
I read the ipad can trickle charge on newer computers but some wouldn't provide enough power. Asus et al have released utilities to increase the power to the usb ports.
I can't post the links but endgadget has an article about it providing links to those utilites. They just talk of apple devices but does this work with the nook?
It comes with a charger for US-type sockets and only if you charge your nook with this (and yes, it is proprietary ) it'll charge quickly. It does seem to charge when you connect it to a standard PC USB port but at an extremely low rate.
On the device Micro-USB (not Mini) is used.
You say it does seem to, do you mean from personal experience? How slow? It sounds like that if you do own one it was so slow you didn't let it finish.
Like if it's 8hrs overnight, I can live with that, but I want to confirm that there is a plan b and not solely rely on their cables.
And as I mentioned asus and others released utils to give more power output to the usb (although these seem like their were only created for ipads). Wondering if those utils speed things up.
for ex, google asus ai charger to see what I mean.
I received my nook Color a mere few hours ago so I can't tell you a lot about its charging behavior It "seems" to load slower via standard USB... if you want to know about the details check one of the large threads on the NOOK and its rooting. I remember reading some information about the USB connector and its peculiarities there.
Ah you just got it. I see.
I found this on the root thread:
'
"There are 12 pins coming off the connector. It looks like there are no pins for the standard micro USB portion, only the extended 12 pins. 2 pins are used to bring in +5V, 2 pins are for signal ground providing a hefty circuit for the 2A charging. USB takes up two pins, and as far as I can tell 2 more are for each LED via current limiting resistors. Two more pins go to discretes that I haven't identified, and two more pins are unconnected. I'll take my scope to them when I have some time."
Not sure what he means when he says no pins for the standard micro portion...
Maybe the plug doesn't have standard USB pins, but the NOOK itself does have standard USB pins as well as the proprietary ones. Because I have trouble inserting the original B&N plug, I went out earlier today and bought a standard Micro USB cable...
I connected it to the nook and it said "not charging", so I went out to do some shopping (10-20 minutes max) and left it at 89%... when I came back it was at 93 %.
So it DOES in fact seem to charge albeit slowly.
Thanks. It's weird, lots of comments of its own cable not fitting properly.
As long as it charges with a normal cable I'm good.
I guess it is charging... however there is a slight chance, that it's NOT charging and the battery charge display is lying (de-calibrated). I don't think so, but I'll only know for sure after a few more days of using only the standard USB charger cable.
Just reading up on USB chargers, and I found somewhere in a thread here about phones defaulting to smaller ma when charging via USB if the connector didn't have the data pins shorted or something.
So, I was wondering a couple of things:
1) If the default charger supplies 700ma, do you think that is the most the Nexus S can draw? Does anyone have one of these shorted USB chargers? Does it charge the NS faster?
2) If it does charge faster, how hard would it be to do something similar to shorting the data connections? I have a generic AC-USB cable which I currently use for my iPod touch.
3) Is there a way to check if it is already shorted out? The USB charging port looks similar to ones on my computer, but I'm not sure what to look for.
Thanks for any help! Maybe if we can sort out this stuff, we can provide a solution for those looking for faster charging!
it does work safely, i'm using a 1000 mAh charger at home, and a 2000 mAh charger in the car both are from aftermarket eBay/DealExtreme charges.
no overheating
and charges faster than stock

Ok thankyou for that AllGamer, I'll think of possible ways I could mod the charger now
The only reason it is slow is because of the USB charging brick instead of just a charger.

I know it's a wrong thread, but anyone has any pointers as to how to short a regular USB cable to make the phone think it's a power adapter cable?

Nah it's not the wrong thread that was one of my questions! I'm not sure exactly where you would do it, but maybe if you skinned the wire, then cut the data lines it would work?
Not sure which end you would do it on however, but that may not matter. Any other ideas?
The two center pins in the USB carry the data. If you pull them out, the cable won't be able to connect to the computer.
Sent from my Nexus S
Wow - you don't need to do this and you wouldn't want to in a computer anyway.
The USB specification says that 500ma (@ 5v) of current should be available from a computer's USB port. Of course, the actual wires can carry much more than this, so manufacturers can tell their phones to takes as much current as is offered.
Almost all computers limit their USB power output accordingly - this is why some opld usb-powered external hard drives needed 2 USB plugs to get enough power. The only computers that I am SURE emit significantly more than 500ma on their USB ports are first and second generation MacBook Airs.
Some phones, the N1 and every other HTC specifically, look for a specially shorted cable to "know if they are plugged into the wall adaptor" as opposed to a computer USB port. In reality, this is just a way to make you specifically buy HTC chargers as opposed to third-party off-brands, because plugging one of these phones into an off brand charger will limit the current draw to about 450ma.
If you want to know if your Android phone thinks that it is in "USB" mode or in "AC" mode, just plug the phone in, open the dialer, enter *#*#4636#*#* and then select battery info. If your phone is one that cares (not all do), it will say USB if it thinks it should be in USB charging mode, or AC if it thinks it should be in AC charging mode.
I would not try shorting out the middle pins in a cable and then plugging it into the computer. First, most will probably just disable the USB port completely, shutting off even power you could draw. Second, if it doesn't shut down, you run the risk that a badly-built USB port might not properly limit the current to 500ma - and since they are not designed to furnish more current than that, you might melt something expensive or start a fire. third, if you make a mistake, you risk shorting out either your phone or your computer, which might ruin your day, week or month, depending on your financial means to replace the system that cooks itself.
I would just run out to your local store, pay 15 bucks for a 2A third-party usb charger brick, and go to town. That will work perfectly - this is what I use, and it probably cuts the charge time by 30-40%. Obviously, this indicates that the NS is not capable of drawing a full 2A - I have not put a meter on it, but I would bet that it limits itself to somewhere just under an amp in.
I have recently bought both a 2A wall charger and car charger and my phone does not recognise either of these as anything more than a 500mA source.
Is it really just a case of opening the car charger up and shorting out pins 2 & 3? they are currently not connected to anything in the charger.
If it's indeed a matter of shorting the data lines, then I think you can skin the wire as suggested by others, but then cut the data lines, short the end that leads to the phone, leave the end to the computer open. I think it's the phone that tries to determine whether the data lines are shorted.
Edit: Can someone measure the continuity between the data pins with the stock charger? I wonder if they are shorted. I'm still waiting for my Nexus S to arrive, so can't test it.
Yup, the data lines in the stock Nexus S charger ARE shorted.
I just modified a cheap 1A car charger by popping it open, soldering the 2 data lines together and putting it back.
The report on the Nexus S before I did this (*#*#4636#*#*) said "USB", and afterwards it now says "AC".
I will report back after I make a road trip if this improves the GPS + Pandora + Screen in car situation. I suspect it will.
----------------
Yup, the car charger seemed to actually maintain and increase the battery this time. Seems good.
The NS supports chargers output to a max of 1000mA, as it says on the back of it, where the battery resides.
My nook coolor has worked perfectly since the day I got it, the second day after release. Last night when I put it in the charger I noticed that if the cable was pushed a little bit up when then nook lay flat it lost connection. It actually been charging itself up to 50% untill it stopped charging beacause of the cable.
I'm thinking that the micr usb port is the probleme here, is this a known issue?
I've seen reports of this being a problem. Usually the cord is at fault. You should be able to exchange it at a B&N
The USB port on the NC has two stages. The first stage has the standard 5 pin connections, but the second stage has 12 pins that are specific to charging the Nook. If you don't push the cable all the way in, it won't engage the 12 pins and won't charge properly...

I've noticed this too on my NC. The cable plugs into the device easy enough but the slightest movement of the cord causes it to cycle between charging and not charging (orange and green 'n' on the cord). This makes it virtually unusable while plugged into AC power...not a deal breaker but a pretty annoying little bug. Will a new cord really fix this issue and will B&N replace them for free?
On similar hardware, often times that is an issue with the internal jack being tweaked too often and breaking the solder connections, or the copper traces themselves. From the tear-down pics, it's all surface mount, which means if it IS the jack, you're most likely SOL if not under warranty.
I've had my NC for about 3 weeks. My micro usb connector is no longer connecting reliably. I have to lay the NC on its face for the connector to maintain a data connection. The power connection is more reliable, but not 100% either.
Hello
My phone thinks its charging when I connect the USB, but actually loses power even though I'm not using it. Then when I remove the USB cable, it still says its charging. Even after reboot, it still thinks it is charging. Only way to remove the charging icon is to hold volume up button + power button untill it vibrates 3 times
Only way to charge it is through the magnetic cable I bought for it. But even when I remove this cable, it says its still charging,
When the phone reaches 100%, there is no problem whatsoever with the connection detection etc. It all works fine.
This started just out of the blue, already tried the PC Companion app to restore it to original firmware.
Funny thing is, I can still use the usb port to exchange data etc, it just wont charge. And it gives false information about it charging while there is nothing attached to it.
Thanks in advance
U will gwt unlimited battery like that
Lucky!
How did u do that?
Wish that was true! Wish that it indeed could pull power out of thin air
BTW; I tried to adjust the microusb tongue en cleaned it out, even with a air pressure can blowing into it. Still no luck.
When I connect a USB cable without putting the adapter into the wall socket, It doesn't register as charging. Only when I put the adapter into the wall it says its charging, after this it doesn't matter if I pull the usb cable out. It still says charging

Hmmm... I'm not very sure if it's a hardware or a software issue... try using flashtool instead of PCC just in case!

What is Flashtool? I haven't even rooted this device. Will try a totally different rom
Well, I've had the USB-charging port replaced. Still same issue!
Usb has 4 (generally) wires Red and Black for +-5v and another two for data (most often white, green).
The question is: Do i need all 4 wires for car head unit to recognize android auto by connecting the usb?
If i cut voltage (red and black wires) will it still recognize it?
If not, if i give external voltage to phone to red and black wires i have cute, will it work now or not again?
My main problem for asking this, is that car head unit does not provide much voltage when connecting phone for android auto and decharging slowly..
I am sure if i cut voltage wires as i describe above and connected to a light charger i will have more voltage.
But i afraid destroying head unit so i prefer to cut voltage of head unit, and use only voltage from lighter charger..
Any info about this?
I am actually going to install permanently an old phone to the head unit only for android auto.. And i want to be changed.
Anyway i decided to destroy a cable to find out myself..
By only cutting red wire, android auto loose connection...
But how does it see it?.. If i put a resistor or something could i trick it?..
If anyone know would be very helpful.

Hi Sosimple
I have no possibility of trying it myself but I guess there are two possible problems that cause Android auto to stop working.
1: mobile
Your phone recognises that it isn't being charged so there can't be a Android auto connection. To test this out, connect a charger to your modified cable (connect plus and minus to the charger and d+ and d- to the car)
2: car
Your car recognises that there is no draw at the USB port, so no smartphone is connected (this is unlikely though, because the smartphone could have a full battery). To test this, try putting a resistor in between plus and minus of the cable. (10Ohm~500mA so don't go below 10Ohm. Try higher resistors first)
If none of the above work, consider buying a USB y cable (used for external HDD) to cross out possible mistakes
Regards
Thanks. I will test a resistore some day..
My car (intellilink system is called, opel corsa) has 1 usb only. But you can connect a 4 port usb switch, so to use 1 port for a usb stick with mp3, and another usb to connect phone for android auto at the same time.
And working fine this way.
If i use a y cable to connect it 1st usb to lighter charger, 2nd microusb to phone, and 3rd usb to usb switch, i really don't know what is going to happened regarding voltages. If there is any danger for the intellilink system of opel corsa.
I don't care if anything happens to phone as i have an old to test, or the switch, as it is cheap, but i do care for intellilink as it is expensive. That's why i haven't test a y cable..
Sent from my SM-G9350 using XDA-Developers Legacy app
If Android auto works with the switch, no need for trying a resistor (because only the switch could measure the current draw)
So the reason it doesn't work must be the missing charge voltage at your phone. Did you try connecting + and - to a charger?
Your switch gave me another idea. Try finding a powered switch (a USB powered or directly 12v powered one). Those switches with external power exist and they could provide enough amps to charge your phone while using Android Auto.

Yes i also had the idea to take a powered usb switch. I couldn't find one where i live yet..
Although if i found one, i also have the fear if i could harm cars intellilink system..
Because: Intellilink takes voltage from cars battery and give voltage to usb.
If i then i take a powered usb switch, which i will connect it to usb charger lighter (which takes voltage from car battery) and connect then the switch to usb of intellilink system, who really knows what happens Regarding voltages? All take power from cars battery. I don't know if i can connect them without destroing intellilink system..
Thing become to complicated to be sure what will happened.
I read alot in forums but haven't read something similar..
Anyway if i test it, i will post the result..
Sent from my SM-G9350 using XDA-Developers Legacy app
Those external powered switches usually separate input data and output voltage completely, so there is most likely no connection at all
The point that both devices are powered by the same source (car battery) even reduces the risks of damage because of the same minus/ground potential. (I would even connect the minus poles of all devices if I soldered myself a y cable, just to have all GNDs connected, but there is no need to do so.)
Can't you order one from Amazon or eBay? I don't know where you are from but most Chinese or Hong Kong sellers (eBay) ship almost worldwide.
I hope it works for you somehow.
I probably will create one by muself.. I live in Greece. I have already created one, doing something similar. With an on/off button i choose if i will change phone from usb charger from lighter OR connect to intellilink (and disconect from usb lighter charger at the same time)..
I experiment with this. It looks to work well as in on i have intellilink connection, android auto, and in off i disconect from intellilink but charge from usb charger in lighter..
I'll keep this for some time..
