I'm looking for a cover with microsd slot but I haven't found nothing. So I want to know if there are problem to make a thing like this or nobody hasn't thinked about it. I think that make it is possible because there are some OTG that read microsd(I have it) but with it I can't charge the phone and I'm afraid of break it when it is in my pants. I've thinked to make a cover with microsd slot and external battery(like the image below), it is possible?
The pin you marked with <?> is the key to USB OTG. In order for your stick/card to work, you'd have to connect that pin to ground. Then, when you wanna charge/access the phone (from a computer), you'd need to disconnect that pin.
The main problem that I see is that there isn't enough space between the original cover and the phone/battery. The second problem is that our beloved Nexus is old and many thinkers moved away to newer devices. And, to access the USB port internally, you'd have to open the phone, which would void the warranty (if the phone still has one).
PS: Still remembering those kind of math exercises from high-school
Why i need to disconnect the key to USB OTG when it is charging? If I'm right to charge the phone we only use the 5v and ground pin. I've thinked about create a cover like the picture below with the micro sd slot, so without opening the device. Hope that you can help me again
To put it simple when you use a OTG device (like a card reader) your phone powers the card reader (electricity flows from phone to device). When you connect your phone to a computer/charger the device will charge your phone (electricity flows from device to phone). This functionality is controlled by connecting pin 4 of the microUSB maje jack to ground. I've read that some Xperia phones have a 3rd option: if you connect a certain value resistor between pin 4 and ground, you could power both the phone and the card reader from your charger.
Cheers!

Hi folks,
i purchased a new usb cable today. its retractable, called 'Sync "N" Charge'. it is essentially the same connections as the stock usb connection cable.
the problem is when i try to connect my (Imate Jam) to my PC(winXPpro) it either freezes my pc, or puts up this msg.
USB device not recognised, one of the usb devices has malfunctioned, click here(opens up systems properties).
It does charge the Jam. well atleast the orange charge indicator lights up(i havent checked for actual charge).
The device drivers for my Jam are fine seeing as it still works when i connect with my original cable.
my original cable works fine, even if i switch straight back to it after trying to connect with the new cable.
I think the cable may be wired incorrectly eg postive and neg prolly fine but the data pins are screwie some how, sound like a reasonable guess?
Is there something else that im not thinking of/dont know about that could be causing the problem?.
bleh just typed all that and answered my own question. the data pins in the new plug are a little bit shorter than the power plug. I use a silicone case on my Jam which stops the plug from pushing in all the way by like 0.25mm. took off the case and bingo problem fixed.
I hate when that happens.
Ok well i might as well say that its a nifty little piece of hardware now that i got it working.
Which leads me another question, the reason i got this new cable was to be able to leave it in my bag and pull it out when i wanted to use my Jam like a 1gb usb card(1gb sd card). the times when i wanted to do this would be at university.
is there a way to make a pc recognise the jam like a usb drive instead of a pocketpc upon connection? i wont beable to install activesync on university pc's.
Thanks
Speedn
I am using the original micro-usb-b charger that came with the phone.
I think I accidentally damaged the charger since pin #4 is missing (see: en.wikipedia.org/wiki/Micro-USB#Physical_appearance).
Although the charger works fine I suspect that I might be damaging the phone by using it.
Should I continue using the charger or should I buy a new one?
Thanks in advance
from ehow.com:
Micro USB Pinout
Like mini USB, micro USB also used a five-pin connector. Unlike mini USB, the fourth pin is actually used to differentiate between an A and a B plug. The pin assignments are exactly the same as mini USB, except that for a micro A plug the fourth pin is tied to ground, and micro B the fourth pin remains unused.

So I don't think you're damaging your phone. I haven't checked, but it might be the way the stock charger is designed.
welcome to XDA!
I'm wondering, if I'd want to solder something to the USB port (internally of course) and the attached device is not connected, would I still be able to use the port as before(charging, etc.)? Provided I would not use > (IIRC) 5V together, could they be use simultaneously?
Why I'm asking:
I found an old OCZ Trifecta (SD to USB-Adapter with MicroSD slot) laying around. Stripping the thing down reveals a really thin logicboard, which fits almost perfectly under the normal back cover.
So I thought, if I could wire the USB connector of this adapter to the internal one, I could have additional storage. I don't know if this specific adapter is SDHC compatible, but since there are newer ones around, I could get one of those.
Thus I'm asking for advice:
a) technically possible?
b) if yes, how hard is it for a semi-newb?
c) potential trouble I should be aware of? Not meaning loss of guarantee, more about possible hardware destruction.

In theory if you rigged it up to work like usb otg and charging then you might be able to get it to work. I think it takes a resistor to trigger it.

No you wouldn't need a resistor, you just need to short pin 4 and 5 together on the micro usb side. That's what makes it an OTG cable. Check out the picture I attached. That should be the wiring you need to make it work. Refer to the link below.

In theory it should work. The hardest part is attaching wires to the pins of the micro usb connector. It so [email protected]#$ing tiny... not the easiest thing to do. Unless the pins of the connector goes though the other side of the board, then you can solder onto the solder points itself. That should be a lot easier. Any potential problems? You could screw up your micro usb connector... then you might not even be able to charge it if you lose that...
Good luck. I would be interested to know if you succeed.
BTW Micro SDXC 64GB in FAT32 works in my Acro S running CM10 with Nova Kernel. You can gain a lot of storage!
is it possible to charge mobile while it is in OTG mode?
Thanks for your inputs.
According to this video it doesn't seem to be too easy, guess I'll need to wait a few days for a buddy, I'm not yet skilled enough for such delicate work.
If somebody has more skill and faith in his/her talents, you should be able to get an adapter for <5€ practically everywhere.

Thank you this is what i was looking for
Hi all,
Such devices like Xperia U,P.... iPhones,
and some other devices which have no
external storage but USB OTG supported,
can use SD card or pen drive with OTG.
There are many kind of OTG cables, but it
is very hard to carry an OTG cable & a card
reader all the time, so i am thinking of an
OTG with card reader in a very small (as
small as it can be) form which can be carried
all the time.
the card reader will b stored(may be fixed)
with the back cover(as shown in the pictures)
.
i am usuing very small card reader slot, thin
wire(like insulated copper coil wire), a tiny
siwtch(on/off).
pictures

http://d-h.st/NU4
As we know, in OTG pin 4 and 5 are
shorted so i am usuing a tiny switch, when i
switch on, the pin 4 & 5 are shorted & the
cable will work as OTG, & when i switch off
it will turn as a normal USB cable, so there
will be no Battery Drain.
i am trying to configure it ,but having
problem when soldering the wires with the
micro usb male port.
The connections are so tiny, so it is very
hard to make it alone, i tested it in a bit
large form & it workes, but in small size as
shown in figure it becomes very hard to make
it ,,,,,,,
i am requesting you all to try it & make it
by yourself,
if we can make it personally i think one day
such cables will b available in market in very
stable form for all usurs.
With most manufacturers removing micro SD card slot from their flagship phones, Oneplus included, has anyone been able to expand storage through USB OTG? I'm currently on a different older phone, which has micro SD card slot, and I recently expanded my storage by replacing 256GB card with 1TB one.
While my OP9Pro is on the way, I'm thinking of purchasing a small USB-C micro SD card OTG adapter (something like this: https://smile.amazon.com/gp/product/B09L4NDV4T), unsolder the USB-C plug and insert a short ribbon cable between it and PCB. Then plug it into USB-C on the phone, and tuck the PCB with micro SD card inserted somewhere between the phone back cover and a case.
This obviously will require some case modding/dremeling to avoid bulges, but my biggest concern is whether or not I'm able to solder the microscopic leads on the USB-C connector and whether this whole setup will work anywhere close to internal micro SD card on older phones.
Am I dreaming or has anyone attempted this before?
Interesting idea, I'm curious how it works if you try it. Although I can't imagine needing that much internal storage all the time. I just have a dedicated 1TB USB-C flash drive that I copy stuff to that doesn't need to stay on my phone all the time.

I didn't mean that I need all 1TB right now. I went from 256GB -> 1TB and currently have over 550GB free space left. However, I do backups (apps, using SwiftBackup, and TWRP backups). App backups must be on the phone all the time, since it's automatic and syncs to OneDrive; TWRP don't have to, but I like to carry them around just in case.. I also save all camera photos/videos to SD card. So it all adds up, and 256GB on the phone that I'm getting will feel tight.
I'll try this idea and update this thread if it's at least somewhat successful.
Would it not be easier to get a lil usb c extension cable and somehow modify the phone case than the actual phone itself?
The storage expansion card for Xbox Series X/ S delivers an additional 1TB of external memory while maintaining the same peak speed and performance of the console's internal SSD for a streamlined gaming experience.
Unfortunately, guys, using USB OTG is not an option. I recently tried to use the above-mentioned USB-C adapter without worrying about it sticking out too much, just for the proof of concept, and found that the card gets too hot, i.e. it's using a lot of power. This will kill the battery very quickly.
So this makes the idea a non-starter.
