USB SDHC Card reader

Can anyone recommend a USB SDHC card reader that I can mount on my CM9 touchpad?
I've got the USB Y cable and can see the contents of USB sticks in Astro file manager, also managed to view the pictures on the memory card in my Olympus SLR camera. Unfortunately my other camera Canon compact camera doesn't support mass storage mode, so i want a SDHC USB card reader that i can plug into my touchpad to view the pictures on the memory card.
I've tried a couple of SDHC USB dongles and haven't been able to get them to work, i plug them in and nothing happens, no blinkning LEDs, no files showing in Astro.
So has anyone got this to work, if so can you post a link to the card reader you use?
Thanks!

Make sure you're file manager is set to show all/hidden files.
I use tiny Dane elec readers but any should work.
Make sure they are fat 32 format.

Does USB OTG work on cm9?
I can't get it to work with my nexus OTG adapter?

Yes it works
You need correct y and OTG cable and appropriate power source.

I managed to get astro to show the files on an USB Key, but when plugging 2 diff Card readers, and an SD card (fat32), although one of the adapters shows a led, USB storage remains empty under Astro...
any ideas?

I took a punt and bought another SD card reader from amazon and it worked!
In case anyone else is looking for the same thing it's called "Daffodil UCR03 Ultra Slim all-in-1 USB 2.0 Memory Card Reader" on amazon.co.uk. This reads my 8GB SDHC card fine. Cost me about £3.50.
Can't include a link as forum won't let me cos i'm a newbie.

Would this work with WebOS too? And does this need external power source such as a USB hub?

I'm a total noob at this and could use a for-dummies version of how to connect a USB SDHC card reader to the Touchpad (I only recently flashed CM9).
Specifically, I would appreciate if someone could point me towards the exact products I would need in order to set up a USB card reader for my TP. I assume that I will need (1) a USB card reader (such as the Daffodil product mentioned by obo789) and (2) a micro USB adapter of some sort so that I can connect the USB card reader to the TP (is this the "OTG Cable" mentioned)?
If so, is there a particular USB card reader and cable that people recommend?
Once I've obtained the necessary products, would I just D/L Astro File Manager from the App store? Would EZ File Manager also work?
Sorry for the noob questions. I searched this and other forums but could not find a definite answer.

All the details on how to connect are here - http://forum.xda-developers.com/showthread.php?t=1582771&highlight=otg
It just needed a 5 second search.

Thank you so much for the link. I kept searching for USB card readers and nothing came up (here and on other online forums). I didn't t think to search for USB OTG compatibility since, until last night, I had no idea what USB OTG meant.
Thank you again for your help and for pointing me in the right direction.

The two I got working were both double capped style, one cap for the SD card and another for the USB plug. One is branded Dane Elec IIRC and the other was a free promo item from Panasonic I got a while ago.

Anyone know where I can get a y cable in the UK?I've tried all sorts of searches on amazon.co.UK and eBay, annoyingly the ones linked from amazon.com won't ship to the UK

4-in-1 OTG adapter may save cables.

Hardware is one thing, I just purchased one of these 4-in-1 adapters linked in this thread: http://forum.xda-developers.com/showpost.php?p=31034220&postcount=35
But your issue may be software/OS related, also discussed in that thread: http://forum.xda-developers.com/showpost.php?p=30952816&postcount=34
or better yet: http://rootzwiki.com/topic/33033-otg-usb-insufficient-available-bus-toolthingy/#entry921673
IMHO: you need the USB unmout utility presented there. Try it if your USB flash drives ot USB SD card readers don't work. You might just have a "insufficeint bus power" response, which the utility can correct. I can now read all my camera & camcorder SD cards from a USB interface that failed prior.

In theory you can use your HP charger connected to it as power source.

That should work and would have a lot less cable clutter than the original set up. With that all you would need is any microUSB charger to power it. There is also one for sale that has a male USB connection for power instead of a female micro USB. With this it would be easier to hook to one of those portable USB chargers that use a full size USB port.

=== Review of Juiced Systems ACA adapter ===
I got this: http://www.amazon.com/Samsung-Multi-functional-Connection-Kit-Compatible/dp/B006MJZOMW
It appears to be a USB OTG ACA compliant device. Sadly it's for Galaxy Nexus Products and the full ACA compatibility doesn't appear to be implemented in hardware and/or software on the Touchpad with CM9.
1- It does function as OTG host port with the Micro usb from a charger powering the down stream devices. :good:
2- OTG to devices on USB/microSD/SD interfaces works well, but only one at a time for memory volumes (FAT32). Not sure if that's a software shortcoming.
3- Success with a wireless adapter for Logitec mouse/keyboard on USB. :good:
4- Haven't found an NTFS mount solution for Touchpad w/ CM9 nightly 0903.
5- It does connect to the Touchpad, but not with the HP folio case or any case as it's a close fit.
6- The ACA charging of the touchpad while hosting, or otherwise, sadly doesn't work as it was reported to function on SG2.
7- ACA indicator never lights up for charging or host.
Initial Result:
- At $20USD there are fewer cables, but full ACA charging doesn't work, which was my motivation to spend more.
- OTG to devices on USB/microSD/SD interfaces works well, but only one at a time for memory volumes FAT32.
- The physical connection seems a little weak to me. I almost feel like it could break off damaging the adapter, or worst, the micro USB interface.
Further tests:
- I want to check if the Wirless mouse/keyboard on USB can be used with a SD card in either slot.
- I'd also like to test of external HUB with devices further downstream such as self powered HDD and seperate USB Mice, Keyboards (for deskside use).
- Can anyone recommend a ICS compliant USB GPS & app?
Although this setup with: Touchpad, USB battery, Juice adapter, is simple and elegant, its pricy for features I'm not able to use (charging while host). I'm not impressed it will be rugged enough for field use.
Here is my recommended portable solution, which is also cheaper:
- HP Touchpad
- Battery soulution of choice <<< $4.25USD
- OTG host cable & power Y combo: http://www.ebay.com/itm/Micro-USB-H...i9100-S3-i9300-i9220-i9250-XOOM-/140825132367 <<< $6USD
- USB memory / flash drive of choice
(or other USB device that is ICS compatible with HP Touchpad)
:victory:

Will do
Im getting the camera tomorrow and the cables and adapter should arrive soon!

Any Roms that support usb otg

Are there any Roms that support usb otg.
I'm on clean rom 2.5 and can't get it to work. Also the few Roms I have tried it hasn't worked.
Sent from my SCH-I535 using xda app-developers app

CleanRom 2.5 (and 2.1 before that) and it works fine for me. Higher-drain usb devices might need their own power source.

What kind of usb otg are you using maybe I have the wrong cord. Did you have to enable any options?

I used what I thought was a non-OTG micro-usb-to-usb adapter, and then a cheapo OTG cable and both worked with a wired Xbox 360 controller. The cable also worked with a flash drive. I haven't really tried any other devices.
The ones I used were:
http://www.amazon.com/T-Flash-Adapt...UTF8&qid=1350406382&sr=8-1&keywords=otg+cable
and something like this:
http://www.amazon.com/SANOXY-Micro-Male-Female-Adapter/dp/B0027YYMU6/ref=pd_sim_cps_8
I didn't enable/disable anything when I did the tests -- it just worked. Possibly I had done something earlier, but I can't remember anything specific, and haven't done any specialized hacks for this.

Yeah I have the same cord odd. Oh well .
Thank you for taking the time to supply the links.

Is it possible to attach a powered hub to
A) Attach higher power-requirement devices that do not have external power
and/or
B) Attach multiple devices for simultaneous use (say, a keyboard and a mouse
??
(my USB OTG cables are in the mail)

I *believe* both answers are "yes". You can attach a usb hub. A powered one should give power to the devices, or you could try a "y" usb cable to provide power as well.
btw, here's a video showing off some of the capabilities (i believe this is the international version):

Shoot. I guess I'm not sure what else to try so hopefully someone else can chime in. I haven't tested it out recently, but I'll let you know if I happen to discover anything.

Works fine for me...just plug the otg cable in (I had one from my old fascinate I got off Amazon for like 3 dollars...and I can either plug a single item like a mouse or flash drive straight into it or a hub that can be powered or not...if you plan on using an external hard drive is suggest plugging it in...I believe the phone holds up to like 6usb connections at once but don't quite me on the exact number...I have had a mouse, keyboard, flash drive, sd card reader, and second phone all plugged in at once...only think I've found is that not all usb hubs will work for some reason...I use a 30 dollar (at bestbuy) belkin 6 port hub and never had a problem...to have it powered though you have to plug the actual power cable on the hub into a power source and run a usb cable from the hub to otg cable...as far as I know every room should support this...I used liquid smooth which is an aosp rom and it works great, also works great on any tw Rom as the capability is built into the phone...hope this helps anyone with questions about this...only think I haven't tried is a hard drive mainly because I have no need to buy one but it should work...and if it means anything I use all 2.0 cables and accessories, no 3.0 or 1.0

[Q] USB OTG Support?

I've searched everywhere online and i'm getting conflicting results, so I was wondering if anyone who has one can confirm if the idol 3 5.5" has USB Host or On-The-Go (OTG) capabilities. Thank you very much.

Yes!
I'll confirm 100% I have used the following SUCCESSFULLY:
- 3 port OTG cable with TWO USB thumb drives plugged in, one USB3 64GB and one USB2 8GB
- 1 port OTG cable with ONE USB super nintendo controller
- 1 port OTG cable with generic USB 2.0 SDR receiver for Radio tuning (scanner capabilities confirmed)
I hope this helps!

Mmmh software talking, I do think so. But hardware talking, it's not always the case. My current phone as kernel 3.4.67 which can theorically support OTG but hardware is not compatible, so I can't use OTG at all :/

Awesome! Thanks!

Usually, phone mounts the USB storage automatically and display a pop-up window.
If not, Go to Settings > Storage > Mount USB Storage

I tried otg also, in 9 of 10 cases, phone reject usb, in one case connections was achieved, and i can copy files from usb. But, even in that case, after some time, connection brakes. Annoying. This phone definitely support otg, but something doesnt work well.

Samsung T3

The Samsung T3 external SSD is USB type C and is extremely fast. Using the stock cord that came with my phone I can make a twrp backup faster than to the internal storage.
Anyone else use one?

That's because your phone has to read and write from flash at the same time. My OTG cable and USB 3.0 drive i've had for 2 years os still faster than backing up internally also. But I agree, the T3 would probably super tots.

The T3 is also very fast with the computer. Transfers 5gb in seconds

I used micro usb otg cable, then micro USB to type c adapter, into 6p. Im saying I used a type c adapter and I think that's why it wasn't connecting to the flash drive but either way whatever happened it was not connecting and I tried numerous times I even tried apps like stickmount

Whether the nexus 6p works with exfat or NTFS formatted drive
Please confirm

3rd party app will mount exFAT-formatted T3

I just took another pass at getting my 6P to work with my exFAT-formatted T3, and this time around (Android 7.1.2) saw multiple paths to success.
Firstly, this time, when I plugged in my device, the system presented a notification, which led to a dialog asking if I wanted to "format the device for mobile data storage" – which would have meant reformatting to FAT32. Not what I wanted, but pretty cool that it was an option and I didn't have to go digging.
Secondly, a quick googling turned up a third-party app that will mount exFAT volumes. It's called Paragon exFAT/NTSF (I don't have permission to post urls here yet). I had to pay $5 for exFAT support, and it wanted Total Commander (free) to browse and operate on the files.

Anyone know of any good adaptors similar to the OTG which would allow to connect USB memory sticks via the USB-C port.

I havent used them but some companies are making flash drive with usb c and usb a if all you want it for is a flash drive you can get a flash drive that works without an adapter

Be careful of hard adapters, they (Ha Ha, YOU) will break themselves or your port
Edit, these may not be OTG also. Yet similar OTG 90* adapters have similar drawbacks/ benefits.
There are 2 like this on Amazon.

I am going to get this soon.
This right angle horizontal, is not yet reviewed, but a sister item with right angle (up) is.
Frys usually stocks this style in micro, maybe a C version is there?

I have used one! The one I use works only with USB flash drives that are fat32 format! The brand of mine is belkin and I bought it from best buy!
Very nice to use this for watching movies and not having to use up storage on the device.
Only drawback is that the usb-c port does not allow you to use wired headphones at the same time! So, I had to go wireless Bluetooth headset!

Curious question. Since this is one of the first phones where the add-on option comes into play (mods), couldnt one devise an external ssd drive moto mod? Either that or one of those all-in-one adapter mods where i can plug in older tech? Im always skeptical about destroying the one & only port on the phone anyway.

In case anyone only wants flash storage I purchased the Sandisk Dual ultra and it works great, usb c and a usb a connector.
Also only have to carry one thing as opposed to two. I bought mine with 128gb storage, preformatted to fat32, was simply plug and play.
