Has anyone found a Micro USB card reader for MSDHC cards out there?

With the announcement that ICS will support USB Mass Storage, I was wondering if anyone had found a Micro USB card reader similar in size to the USB Jig shown in this thread. I saw one a long time ago that was used to flash phones of a specific make, but I can't remember where I saw it. Can someone help me?
PS, I know this is a question, but I figured it fell under Accessories. Please don't burninate me.

Do you mean something like this one, http://www.amazon.com/elago-Mobile-...FKR8/ref=sr_1_2?ie=UTF8&qid=1322087237&sr=8-2 ?

Sort of, but a micro USB port, not a full size USB. Like the port on the bottom of the phone.

Well i don't think they make things like that for consumers, but from that video hey seems to have just used a regular microUSB cable.

As I said, I saw one out there for a specific phone maker that they use for flashing. I can't imagine that someone in China would not make them for sale. I'll keep digging, I guess. Thanks for the response, though.

wait, http://www.ebay.com/itm/Samsung-Gal...ccessories&hash=item3cbb7b1e8c#ht_2377wt_1163
is that what you're looking for?

No, but that's the size I'm looking for. An MSDHC reader that size with a micro USB plug like that has.
I have that on the way to put in the toolkit, though. A USB jig comes in handy.

I thought that announcement was that ICS, having usb mass storage support would mean that it's like how current android roms are. When you plug into the computer you can put it into usb mode to transfer files. It was previously thought that ICS would not have that and would require transfer thru MTP protocols only. I dont think it means you could just attach storage via micro usb such as external sd/hard drive.

No, they're talking about hooking up external storage. Someone was talking on Reddit about hooking up a dongle and a USB flash drive to their phone and how it worked for extra storage when they were going on a flight.

I believe what you are trying to do requires usb host support but I know what I'm saying is not the answer you are looking for so, I'll leave this be for now. Good luck in your search.

I'm pretty sure sure our phone does have host mode support. So you can get a USB host mode cable on ebay for $2 shipped, and attach a standard USB drive. Not the compact solution you are looking for, but it will work.

You are correct. It's not exactly what I want, but it would work. Thanks.

Did you find such a thing (micro-usb to microSD) ?
I have been searching crazy lately (like you, I can't believe that some manufacturers did not had this good idea ?!), but nothing !!!
And I am about to DIY one, based on the following example (but with micro-usb):
http://forum.xda-developers.com/showthread.php?t=1713914
I think, I am going to start with something like:

http://www.newegg.ca/Product/Product.aspx?Item=N82E16820313271
The final goal would be to create a micro-usb to microSD adaptator as small as possible ...
Any better idea ?

OTG TF card reader?

Been trawling eBay the last few days for a TF card reader you plug directly into the S3s micro USB port, and I'm not talking about using an OTG cable and a normal card reader, I want something with micro USB plug on one side and TF slot on the other similar to what the Galaxy Tab has, and I'm sure it must exist somewhere so someone point me in the direction.

Something like this?

Something like that... But just a Micro SD reader so it's small as possible.

Not that it's a big deal, but why not just use the internal port?
I know you didn't want an OTG cable but what about an OTC Adapater (non cable version) with an very small micro sd reader? The SD reader below is what I use. I have 2 actually. One is about 2 years old, the other 1 year old. One goes in my car stereos USB port (had a spare 32Gb sd card so it made sense to use it for music) and is very small hanging out the front.
You could use this:

or
2 - http://www.ebay.com/itm/NEW-Micro-B...505734?pt=PDA_Accessories&hash=item3a7bb42146
paired with
3 - http://www.amazon.com/gp/product/B002HGFKR8/ref=oh_details_o00_s00_i01

Well just think about it... With a tiny card reader stuck on the bottom you can treble the memory and still hold the phone and use it normally and store stuff like Emulator Roms and HD videos on which you can't really do with wires hanging out the bottom, and I'm running low on my 64gb card so this just gives me the best of all worlds.
And anyway the guy who got me thinking about it to begin with managed to find the place that sells exactly what I'm looking for.

USB OTG + Charge?

I just recently got a Samsung Galaxy Note 10.1 and so far I'm quite happy with it --- except one thing, I cant find a cable that lets me charge the tablet *and* use the USB Host (OTG) port... (i.e. read files off a USB drive or play a game with a USB game pad while keeping the tablet plugged in)
Is there a way to do this? it would seem to me that all it needs is a splice to give power to the Power +/- pins on the connector while keeping the OTG Data +/- pins active...? (I know nothing about the pinout so I could be wrong on this)
Just to be clear I want to use the OTG adapter WHILE CHARGING (I've found one device that gives both these options but says "only one function may be used at a time")
Ideas?

Discussed dozen times in 10.1 forum. Actually it is not possible. Build an otg + power cable myself but it only works with timing and with a specific procedure... quite annoying. Wait for a custom rom somewhere in the future as I do.

You may have issues trying this, OTG cables are iffy under Jelly Bean. Some may work, some may not. In fact, Google removed references to OTG support for Nexus devices last November since OTG is so spotty. Splicing a cable that might work may kill it. Decent battery-powered USB and SD hubs are available and bypass the OTG problems. I have the RavPower RP WD01 and love it. The USB port will support drives upto 3T. It also has an SD card slot.

Powering the USB devices isn't a problem, I have a nice hub that powers them without issue, even extremely power-hungry devices. I was wanting to charge the tablet's battery while using the OTG adapter (original thought was for USB-gamepad-ing since high-requirement games drain battery, but I've since started using a PS3 controller over bluetooth so I can use the OEM charge cable and wireless for gaming --- but USB drives I'd have to copy the files over to internal flash or a MicroSD card to view while charging and i've found that the cards dont like files that are 8gb in size... (FAT-32 restriction iirc))

I saw that when I google'd but thought maybe there had been some new developments (especially with how this site's members love to tinker with electronics and write custom firmware). It's not a huge issue, since the Note 10.1 has amazing battery life (it's actually matching or doing BETTER than my iPad in most circumstances) I just like to never run the battery down low.. (why cant tablets have user-replaceable/swapable batters like most phones?!)
Thanks for the info!

Biggest Flash drive?

I have the Samsung galaxy tab s 10.5 and I would like to know if a 256g flash drive will work? I watch movies and TV shows on the go, 64g is not enough (the Simpsons season 1 - 25 needs about 100g) I don't have a computer anymore just my tablet. I bought the seagate wireless plus 1tb and I couldn't get it to work, don't want to order a 256g flash drive and have same trouble. Any help would be great
Sorry no I am not rooted and due to the fact that I use my Samsung allshare cast hub daily and root items can't use the hub

Anyone?

Don't you mean SD card.? Some people say the highest you can go is 64 or 128gb

128 GB is the highest you can go

He probably means OTG cable with a hard drive. Simple drives tend to work the larger drives need more power to work via USB.

There is an available of cable that's a "y".....one leg is the USB and the other is another female micro USB for your charging cable. Can't remember where on ebay I got mine but it does work for my external hard drives with my GS5

128gb sd card is not big enough so I thought k would try a 256gb OTG flash drive. Has anyone tested?

This question left me extremely curious, so I have just purchased an OTG cable which will arrive in a few days. I will test out a few different EXT HDD sizes and post what the maximum my OTG will allow.
I do however forsee an increase in the discharge of the battery for larger storage devices, but we shall see.

Can't wait to see what u find

I'm gonna buy a sandisk ultra 64gb microUSB otg and I was looking for a bigger one but this must be the biggest one they have, can't wait to test it out. What I'll do is if my shows or movies won't fit I'm gonna have to erase the ones I've seen then try to make them fit. I suggest you get a 128gb micro SD card plus a big sized flash drive then you should be okay.

So I bought an OTG cable off ebay, and it arrived. I didn't change the format of any of my external drives as I don't have the space to store anything currently anywhere else. The tablet registers there is a drive connected however it can't mount the storage device due to an unknown format. The externals I tried were 2 portables (1x 500Gb usb2.0 and 1x 1Tb usb 3.0) and 2 desktops (1x 1.5Tb and 1x 1Tb both usb 2.0). Over the next few days I will attempt to reformat the 500 Gb and 1Tb portables, and the 1Tb desktop and see if that produces any results. Due to work constraints this may take a few days, so thank you for patience. Results will be posted as soon as possible. Current format of all the externals is default NTFS.

Another Option
There's another option in which would require multiple devices unfortunately due to the limited storage. Its a product I currently use myself called "Toshiba Duo 2 in 1.
http://www.officeworks.com.au/shop/...flash-drive-toduo64grd?searchTerm=Toshina Duo
Unfortunately I am still working on my other drives. There's is a lot of moving data around (limited to USB 2.0 speeds), so please keep posted on my other externals.

Question Storage expansion

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.
