I have been using an OTG cable (which was not specifically purchased for the N7 - I had one from another device) and Stickmount to mount an SD card reader w/ SD card loaded with videos to view. This, generally, has been working fine, but yesterday I encountered a situation where, while trying to watch something, I was continually interrupted for several minutes at a time. Of course the N7 went into sleep. When I woke it up, I noticed that the SD reader (which has a power./activity light on it) did not get repowered. To restore it I had to unmount it, pull the OTG cable, then reconnect it.
While not THAT big of a hassle, since I was continually getting interrupted yesterday, I was wondering if this is normal behavior for N7/OTG/Stickmout.
Ok, this is a bit strange. I replaced all the hardware components (excepting the N7 itself, of course) -- new OTG cable, new portable SDHX/SDHX Micro reader and the card and it is doing the same thing. The reader has a power light on it, that remains on when it is in use. When the N7 times out (I have it set for 2 minutes), the light on the reader extinguishes as well. When I wake up the N7, the power light on the reader does NOT come back on. Stickmount reports it is still mounted and I can traverse the tree to get to it with a file manager. However, when I try to access anything on the card, it errors out.
I repeated the test with a standard USB drive (a rather small one that would not do for what I am trying to accomplish -- media storage/play to save on space on the internal "SD" card). When the N7 timed out, the light on this unit remained on. I was able to wake the unit and continue on accessing the flash drive without issue.
What the heck is the difference between a portable reader with an SD card in it and a flash drive. And, is there anyway to get the reader to behave like the flash drive.
If anyone has any insights into this, I would appreciate it!

At the point where the light does not come on, I would test removing and replacing the media in the reader. Curious if it then works.

Nope, light doesn't come on, card is not readable. Thanks for the suggestion, though...

Interesting. This sounds like the software loading the drivers for the reader are not working. Each version (over the years) of Linux has different ways to mount USB. I am not sure which method Android uses, so I am not much help. Probably someone on XDA knows the details if they will contribute. Or, you might get support from one of the popular Android OTG media sharing app makers to help explain it.
Have you tried a powered (and/or) non powered USB hub in the middle? Curious if your results would be the same.
Unfortunately I don't have one. I NEED to get one, but not yet.
Yea, I noticed the same problem when I was using android vlc to play videos from OTG mounted stick. If I paused and went away for a while, it couldn't resume when I came back. MXPlayer works better, but only because you can start playing the same video again and it will ask if it should resume where it left off, so at least there is a way to get back to where you were after remounting the stick.
If I copy the video file to the local /sdcard storage, none of these problem with sleep crop up, so it is definitely OTG that goes funny in the head.

good day
a few questions if you don't mind. i have the sprint version and was not sure if i should post my inquiries in the general section...
1) i bought this off ebay:
http://cgi.ebay.com.au/RUBBERIZED-H...wItemQQptZPDA_Accessories?hash=item414abf348c
it's a hard rubber case for the sprint version. fits well but i noticed that upon turning on the unit, the screen gestures seemed to stop. the auto-rotate worked when i pulled out the keyboard but other functions or icons stopped responding. i couldn't even power it off as the screen asking for the yes or no didn't respond. i then removed the case and everything was back to normal. the back part was causing no problems, it was only the front (for the screen). has anyone experienced the same? now i'm thinking of getting a simple rubber case as i think the hard type is gripping the touch screen too much.
2) on micro sd cards. i have a 16gb which gives me no issues with memory. all the programs and applications are installed in the card as well. if i had another micro sd card which i wanted to use, can i simply copy and paste ALL the program contents (and other related folders/items) on the other micro sd? will this enable all the applications i've installed still run? or do i have to reinstall everything into the other micro sd?
other than those 2, very pleased with my phone. currently using an i-tech a2dp headset and i noticed that the sounds are quite loud...despite the volume on the unit being at 70% only. example, i was playing my tunez and my media player volume was at 70%...and my unit volume wasn't even cranked up...noticed that the sounds were quite loud via bluetooth.
cheers
just answered my first question. it turns out that the screen protector i had on was too wide. instead of simply covering the main screen, it was reaching all the way to both edges where the black borders are. when putting on the case, i think this was making it press on the screen harder. i simply replaced the screen protector with a standard fitting one for the htc pro 2, put the case back on, and presto...all's well.
cheers

Yes, you can simply copy the contents of your SD card over to your PC, put in a new card, format it, and then just copy everything back over to the new one. As long as you maintain the same file structure, everything should run just as it did before.

Glad to help
Make sure you save the copy of the card contents that you put on your PC during the transfer, just in case your card ever craps out and you need to restore
Hopefully someone can help... When I plug my Evo into my (off brand) car charger, it makes the SD Card unavailable (like it was plugged into a PC). At first, I thought it might be the charger, but my wife's EVO works fine. Any ideas???
Here are the things I have tried...
- Restarted the phone
- Moved all apps back from SD card to phone memory
- Disabled USB debugging
- Restarted phone again
Update...
When I unmount my SD card, plug in the charger, and then re-mount the card, it works. Pain in the rump though... and in case anyone was wondering, no my phone is not rooted or modified in any way. My wife's EVO works fine with the same charger.
Anyone have any ideas??? I would really like to be able to access my music while the charger is plugged in without having to unmount/re-mount.
Go into settings and change the default USB Connection action from USB Mass Storage to Charging. You must've changed that a while ago and forgotten about it.
Are you using DoubleTwist? It has a feature that automatically mounts the SD card to be used from a PC over the USB cable. For some reason it thinks a car charger is a PC.
This probably holds true for other programs that can auto mount SD to USB.

DoubleTwist was it! I went into the settings and disabled that option. Thank you! This is why I love forums!
THANK YOU!
The same issue was driving me nuts.
DoubleTwist is great; but the xda forum is even better ...
I tried on incredible forum and got someone asking if I've tried the obvious. PPCgeeks hasn't had any replies yet, and google searches only return me to my own threads! So....I'm trying my luck with you guys.
I've got an incredible, and was running the stock 2.1, rooted, and I had the phone set to automount the storage as a disk drive whenever connected to USB. Due to a bug in 2.1, whenever you set it up to mount automatically like this, ONLY the SD card was seen as a drive, and the phone storage portion was not available. You could make them both available, but not automatically.
This was PERFECT for me, because I have a car stereo that accepts USB disk drives, and all my music was on the SD card. The one limitation of the stereo is that it only reads the first available partition. Nothing I can do to change it. So, with that setup, it mounted only the SD, the stereo saw only the SD, and I was in music heaven.
So I got virtuous 3.01 loaded on there, and I love froyo.....except....they fixed the mounting bug, and now the phone properly presents BOTH the SD card and "phone storage" when it's plugged into USB. And of course, phone storage is the first presented partition. End result is my car stereo now CANNOT see ANY music stored on the phone. Worse yet, since it takes the phone some time to do this, the stereo doesn't always recognize that a usb drive is even plugged in, where the timing was absolutely perfect before and it picked it up every time.
This seems like it should be extremely simple, like there should be some setting in the phone to mount only one single partition when plugged into a usb port. But for some reason, after days of searching, I can't find this anywhere - everyone always has the opposite problem and wants to make it mount everything.
Can someone please point me in the direction of a setting (most preferable - since I know it worked under 2.1, I know the phone must be capable of this at the OS layer), an app, or SOMETHING, that just straight up automounts ONLY the SD card when plugged into USB?
Under 2.1, with the "bug", it worked FLAWLESSLY. Every time I got into the car, plugged it in, and bang, music. I don't wanna give up froyo because of this, but it's pretty frustrating. I hope maybe someone can show me what I've missed!
I'm having problems getting my terabyte hard drive connected to my phone with my home made otg cable.
It works just fine with my 2 gig sandisk flash drive, and my USB mouse. So I know it's not the cable.
I'm on Ravers blackedition Rc6 ICS. Just wondering if there's a workaround.
Oh, and I can't get my x-box controller to regester with my emulators, is there an app for that.
Sent from my very own Galaxy.
You need more power to power that external drive. Flash drives do not require that much juice.
Sorry I had to retype the post a few times due to my connection timing out and left some key stuff out.
The terabyte drive is self powered with an AC plug.
When I plug it in it gets as far as telling me that its connected, then reboots my home screen. I go to access the drive and it says its empty.
I can hear the drive working so I guess its scanning media.
If I leave it plugged in it will freeze the phone. And I have to pull the battery or hold the power button. Then I can't access cell or SD card functions. But a few reboots brings it back.

Probably formatted ntfs and the kernel is lacking proper support.
i have the same issue with my 1TB external harddrive. it also has the ac plugged into the wall then i hooked it up to my phone and it showed this...
also mine is formatted to NTFS.
it is probably only reading a fat partition on the external, as mentioned above if the drive is NTFS formatted, your phone probably wont read it.
This is irrelevant but I really don't see the need or the practicality of plugging in a massive (both storage and physical size) hard drive to a handheld device.

All of my music and movies are on the hard drive. its easier to copy the files from drive to the phone, instead of mounting both to the computer and copying that way.

Ok I see, why not get a 64GB SD instead then? Save the trouble of having to plug in your phone to the hard drive all the time.
I was wondering if any of you have the same problem as me.
Just bought the dk20 ion dock and pluged my ion jelly bean to it and:
- first nothing happens wen pluging it in, if mouse and power cord connected it charges and cursor appears.
- doesnt autodetect dock
- hdmi (for me most important) does not work..
- pendrives and/or flashdrives are detected ok
so the dock is as for now a nice charger and that is about it!
let me know if any of you are having the same issues, and lets see if wll together we can do something about it.
I have had zero issues with mine. USB capability seems to be hit and miss. My cheap mouse and old Logitech keyboard work fine. I could not get a Logitech k400 to work though. As for getting hdmi to work make sure the cord is plugged in and tv on. Device screen should be off while plugging it in. Once in turn on, unlock, and it should show up. Then you can pull the notifications down and hit tv launcher. You can also set it with smart connect to auto launch.

Are you using Jelly Bean on your Ion as me?
I have followed your steps and nothing, pluged the HDMI cable into the dock and turned the TV on with the HDMI 1 channel on, with phone screen off connected it (with only the HDMI cable plugged in) and nothing happens. If I use Smart Connect App, when choosing dock it does detect the dock, but the TV mode does absolutely nothing.
Im beggining to think it could be the HDMI port on my Dock that doesn't work properly, I did buy it on ebay.. so you never know!
Let me know what you think, the whole idea was using my Ion as an additional basic PC, but without hdmi it's not going to be to useful..
Yes I am running the Rogers jelly Bean. It is very easy to disturb the hdmi connection when you mess with the dock. I am using a hdmi to micro hdmi adapter. I plug my phone in then hit the power button and unlock it. It then recognizes and shows on the tv. If you pull down the notifications you have options for tv launcher and also hdmi settings.
One thing you can try is connect the hdmi to your device directly and see if it works.

I think it's the HDMI port on my dock then, because it just doesn't even notice the HDMI connection, I'm using the cable that came with the phone, I have a factory unlocked lt28h Ion that came with all the extras, hdmi micro to hdmi cable and smart tags..
I may try doing a downgrade to see if it works ok on the ICS, I have read it had less problems with that version of Android.
Once again thanks ever so much for your help and interested, ill keep the post updated just in case other people are having the same problem as me.
Pd: The HDMI port on my device works fine directly to TV, the only thing is I have to adjust the screen dimensions to 95% now I'm on Jelly Bean so the picture is ok on the TV.

Finally the new Dock arrived yesterday and guess what.. It works like a charm!!!
So in the end the problem was a faulty HDMI port, the seller was kind enough to send a new one for free.
Thank you all for your help, as compensation ill leave a few discoveries I have made so you can use your ion as a spare PC.
For ROOTED devices i strongly recommend Screen Standby App, that lets you turn the screen of whilst the phone is docket and uses 1/3 of the battery, as well as not bothering you whilst watching a film or other tasks.. it has many other functions to.
Another great app is Paragon, which lets you connect external usb and hard drives in any format, specially NTFS, please note that for usb and hard drives to work the power cord has to be connected, due to the drain of power, as device warns.
That's it for now, hope this info is useful for other Dock owners and users!
Awesome I will try this out. Glad you got a good dock to work with. If you come up with other interesting stuff let us know.

NTFS is standard format for Windows and for it to work in Android it needs to be fat32 format. Don't think there is much of a difference other than just the type of format. So you would right click your drive you want to use and format it as fat32. Then put what you want to on it and plug it into the dock. The phone should be able to see it at that point but you will need a file browser to access the drive. I will try it in a bit to confirm it works but from what I have read on the Z forum it should work fine.

Can I change the format without literally format my ext HDD?
XDAプレミアムを使 用して私のSK17iのか ら送られてきた
No. You will have to backup or move what is on the drive and do a format. Formatting wipes the drive and no way around that I know of.
The problem is Android is not programmed to read NTFS format which is a windows format.
But if you install PARAGON app it makes the OS able to read NTFS drives without having to format your hard drive to fat32.
I also have a WD 500GB Hard Drive and faced the same problem, there is other programs but paragon seems to be the one that works best.
Hope that helps, regards and good fortune!
