My first post, but I've been reading in this forum for two months, a couple hours each day. It's habit forming.
Gtab, tnt lite v.4.1.0
I have a USB adapter made by Sigg that has a 16gig microSD inserted. Formatted (several times) FAT32. When inserted in the gtab USB host slot the disk is not mounted without a lot of plugging and unplugging and praying to the gods. There have been a few messages telling me that the 'card is damaged' when it is not. The microSD card works fine when inserted in the gtab's microSD slot. But it can take hours of fiddling to get the card to mount in the USB slot.
After lots of searching it seems that everyone else takes USB flash drives on the gtab for granted. They all seem to work. Mine doesn't, but works fine in my XPpro 32bit laptop.
If anyone can give me some ideas for troubleshooting this I'd appreciate it.
By the way, this forum is something of a phenomenon. After looking at the gtab threads I went out and bought mine at Sears. What better way to get acquainted with Android? My thanks go out to everyone here who has contributed. Someday I might be able to contribute as well.
I think about ways to better manage the gtablet xda forum, a lot. It has become a monster - but it's not a bad monster, more like a cute and cuddly Sesame Street monster.
How to organize all this fabulous information so that it can be easily searched and utilized? Good question.
All I can say is - keep up the good work. This forum is a fantastic resource.
Thanks all
Two thoughts:
First: I'd change the title. This isn't a thumbdrive issue, really, so much as a USB SD Reader problem.
Second: I've run into similar issues myself. But I've noticed that I have a couple odd ball readers tht don't work on Mac but does work on Windows. This may be a driver issue. My suggestion would be to try another SD card reader and see if that makes a difference.
I also have a USB adapter with a micro SD inside of it. I find that it does not mount on bootup, but it mounts fine if I remove it and re-insert it.
I was wondering if there is an app for sending a software command to mount the USB. I have looked, but have not found.
smalis, my question exactly!
Taking aaltieri's reply into consideration I experimented with a plain-jane thumbdrive, an adapter with a standard SD, and my adapter with the microSd. Others have demonstrated that adapters with more than one slot will not work. Both my adapters have one slot only.
So here's the intriguing results: The plain-jane thumbdrive is just as unreadable as both adapters UNLESS you boot the machine with the adapter/thumbdrive in the slot, then remove it and put it back in. Then they all read after a short detection period. BUT once the drives are removed after detection they cannot be read again until the machine is shut down and rebooted with the drive in, then remove it and put it back in for detection.
What we need is a method for mounting and unmounting USB drives. I've searched and cannot find a way to unmount the drive under tnt lite. It does not show up in settings/storage like the sd cards do.
By the way, the little Sigg adapter is very tiny, sticking out only 1/4" from the side of the gtab. I got it at Fry's Electronics for $6. I leave it in the slot full-time and it helps keep the power button from being activated when the gtab's inside it's sleeve. I use a Belkin 'non-slip' netbook sleeve (also at Fry's) and the gtab fits only slightly loose. I use a couple of ultrathin mouse pads/screen protectors, one on each side, to increase padding. The Belkin sleeve is difficult to drop due to the grippy sides. The ultrathin mouse pads are marketed for netbook use, to put under the lcd when closing the lid to protect the screen (also Fry's Electronics - what can I say, I'm hooked on the place).
The idea I had was to have 16gig in the SD slot and 16gig in the USB slot. The 32gig microSDHC's are cost prohibitive for me right now. And I still have 11gig remaining on the internal memory. I'd better get to work filling it . . .
Yeah, I have one of those tiny USB micro-SD adapters also (elago Mobile Nano II USB 2.0 microSDHC Flash Memory Card Reader from Amazon), and am very happy with its small footprint.
I had same idea as you - I have a Wintec 16 GB Class 10 MicroSD (~$30 on Newegg) in the SD slot and another one in the USB slot.
However, I have no problem reading the USB slot after unplugging and plugging it in once, or multiple times.
The only time I cannot read it is when I boot with it in. Then, I have to unplug it and plug it in once.
Yours seems more flaky.
Just wanted to note that I had similar issues reading the contents of a FAT32 formatted thumbdrive when using the default iFileManager on Vegan. I downloaded the File Manager app by Adao Team on the market and I can read the thumbdrive contents just fine when using that app.
A follow up for anyone interested.
I migrated to vegantab 5.1 to get mouse and keyboard functionality. I also loaded the small update to 5.1 that has sniffer included.
I don't think sniffer is much to write home about, but it does mount all the usb 2.0 drives and even all the multi-adapters that I've thrown at it. Some posts have pointed out that the multi-adapters don't work. But they do, at least in my experience. I used a Sony adapter that has sd, micro-sd, sony's memory stick, compact flash, and some other port. My 16gig compact flash cards from my camera are read without a problem AFTER opening sniffer. The iFile manager that comes with vegantab does not see the usb 2.0 or the adapter until sniffer is opened. Then the system sees the drives with no problem.
It works every time.
I decided to use an HP wireless mini keyboard. It's a perfect match for the gtab. I thought about dropping $80 for the new Verbatim folding bluetooth keyboard but the HP allows for much better touch typing and I need to do that. Best Buy has a cd/dcd carrying case made by Init that is essentially a hard case that fits the HP keyboard perfectly one the cd sleeves are removed. There's room under the keyboard for headphones, flash memory, and other odds and ends. With vegatab and the mouse fix, the keyboard is easily detected and the mouse pointer works great.
Anyway, it looks as if the mounting issue is one that can easily be taken care of with an app. Another more recent poster on this issue has noted that changing file managers allowed him to mount usb drives that iFileManager would not see. But sniffer works and it's there for seperate download if anyone wants it. I think it looks like crap and doesn't do much. I'll use it in the meantime, though.

I didn't even think of Sniffer. I have a cheapo USB reader that was intermittently working (1 out of 60?). After your suggesting, if I open sniffer then plug it in, it sees it every time.
Folks,
I don't know that there is an answer I have seen to all your questions/observations.
I will say:
1. microSD post and USB on the tablet are not plug and play like Windows.
2. When I change my USB key or microSD, I always shut down and likewise I
always shut down before removing them.
3. Yes, I know that's a pain if you change a lot, but for me it makes sure
Android's flicted OS searches for, finds them, and in turn properly shuts them
down before I remove them.
For me, in and out as need just doesn't work.

EDIT: P. S. -- You all seemed like sharp guys. Should I have asked if you
are looking for the files under /USBdisk?
In my experience, thumb drive mounting is hit and miss. Maybe it's just the drives that I'm using, but it's unreliable. Also, with Gingerbread and Pershoot's kernels, he references having to revert something in order to get USB mount to work (thinking about it, that might refer to mounting the tab to a computer). I would suggest getting used to unmounting your external micro card in Android and growing out a fingernail or two so you can pop that sucker out. I think this is a low priority to the devs, and maybe it should be.
I've been keeping my eye on this Asus Reader, does anyone else use this reader? What are your thoughts?
40 smackers for an SD card reader - does it come in a platinum box?
I take it that you don't have the dock which to me seems far better value, you have an SD card slot, two USB ports, a keyboard and the benefit of another battery. Alternately, I would use a microSD card with a SD adapter so you can use it in different devices but I wouldn't fork out $40 for this - the price is obscene.
Get the USB adapter instead, better expandability. I just received mine yesterday for $14.x delivered.
Dock… Returned mine (BB/BF $99) last week unopened.
Hi, as you can probably tell I'm new here but definately not in experienced in the tech area. Anyway I'll skip straight to the problem at Hand.
I have been googling hard away the last couple of days for anything along the lines of 'full size SD card adapter for smartphone' etc.
I sadly haven't located one or even seen one, a forum I visited had 1 person in possession of a micro usb powered full size SD card adapter, but was connected to a tablet so I have no idea if it would work on a 3D. No links on where he purchased it either:/
Does anyone here have a link as to where I might be able to buy one of these adapters, or somewhat further information about the actual chances of the 3D being able to support one?
The main reason I need one is because my DSLR camera uses full size SD cards and I needed a way to transfer images to my phone, touch them up with apps and have them ready to share as I'm shooting.
Thanks in advance for any answers.

There is a post somewhere if a guy who added a full sized SD card adapter to his EVO 3d. Looks pretty good and he explains how to do it.

Almost all MicroSD aftermarket cards come with a SD adaptor such as the one below:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231509
I bought one from dealextreme for about $7 several years ago. The problem is fitting the adapter in the phone. But for your use, perhaps you can just use it temporarily without the back cover on the phone.
The adapter has a small ribbon cable that connects to a micro SD plastic piece. The ribbon cable extends out to a larger plastic slot for a full size SD card.
The problem with our phone is that the microsd card sits flush with the battery. I'm not sure if there's enough room to fit the ribbon cable between the microsd side of the adapter - and the battery. If I can find my adapter - I'll check tonight.
The easy way to make this "permanent" would be to use an extended battery back cover, without actually using an extended battery. Otherwise, there's definitely not enough room behind the stock cover for the adapter.
Thanks for the replies but I don't want to have to buy another micro SD to put in a full SD in my camera. I just need a USB card adapter like the 7 in 1 types you see at most stores but one compatible for an evo:/

With Olympus Rom and Chad Goodman's Anthrax kernel it is possible to enable USB Host, which as is sounds will allow you to connect camera straight to evo (with USB OTG Cable). At this time it is really hit or miss whether it will work on your phone, some people have got it to work and others not...That is where I am at the moment. Chad is in the process of making it work on all evo 3Ds as long as they are running a rom with usb host mode enabled (Olympus is the only rom at the moment with this feature I believe). Chad has been able to use the function on his phone and had sucess with usb keyboard and usb external drive.
----or----- Try this guys method..

That is NOT what I was suggesting, I was suggesting that this might work:
http://www.dealextreme.com/p/sd-to-microsd-transflash-card-converter-module-27001
But I don't think it will fit safely into the EVO3D's microSD slot. The plastic piece which connects to the normal microSD slot is longer than a regular microSD - and will crash against the battery, unless it was bent. I was not willing to try to bend my adapter for this check, sorry.
I think your best bet is to root your phone to one of the ROM's that handles USB host as suggested above.

Well I happen to own the GSM model with which the SD card slot would work with this no problem as it is on the side facing outwards without any battery interfering with it. I might look into that at the later.
A further question about gaining USB host through rooting does anyone know how to root a GSM model with HBOOT 1.49.0013 on Vodafone Au? If not then I will have to settle for the adapter displayed above which wouldn't bother other than the fact is that I want to transfer photos from the Full SD to the Micro SD not to internal memory as that could take a while as the files arn't particularly small:/
If this is sounding strange its like the adapter Apple made for the iPad called 'camera connectivity kit' etc. This is a small inch by inch brick that simply plugs into the charging port and accepts SD cards for transfer to the internal memory.
I just got my original ET-R205UBEG OTG cable for my i717 Galaxy Note and can confirm that you can run any size drive off it as long as you power the drive from a separate power source. The note doesn't have the power to power anything more than a flash drive, keyboard, mouse, or card read.
You must format the drives partition to FAT32 because that's all the ET-R205UBEG supports since it's design really for flash drives or card readers using which support this format. You can download the free Windows utility Swissknife which will let you format any size drive with a FAT32 partition.
On a side note, I plugged in a IR receiver just for fun and was able to control my note (somewhat) with the MCE remote control that came with the receiver. I'll do a little tinkering but I suspect I'll be able to expand the functionality of the remote. Right now is can change the volume level, fast forward and reverse, move a mouse pointer around the select and select and run an app. I'm sure there's a lot more I can do but I've only been playing for an hour.
In case anyone's wondering, I got my ET-R205UBEG adapter from greytech .com in Canada - they only sell to Canadian clients and the items not listed on their site. It's $22.99. Call them at 905-470-1425.
Lacie apparent makes a low voltage drive called the Rikiki. I plan to order one and see if the note has enough power to run it. Lacie told me that it should work since it works on the MAC Air when most other external system powered drives do not.
My flash drive of course worked perfectly and respond much faster than the MicroSD class 10 32GB card inside my note. I think I'll be using the OTG adapter a lot more than I expected.
One final note, the OTG from Samsung is my third OTG adapter. The other two (both from eBay) either didn't work at one or kept disconnecting. For my money, $22.99 is a low price for a quality product that Samsung actually will support.
I paid $4 for my OTG adapter from Brando Workshop. It works perfectly fine.
I have a similar reaction as goalcam. What advantage does this $22 unit have over the lower priced units?
How about a Ssd?

card reader
A little off subject, but can someone point me to a card reader that works with an OTG host cable? I've tried 3 here and none of them seem to work. Is there some driver I need to load/enable? flash drives work fine on it. I haven't tried anything else.
Thanks
Hi
I want to get my 6T to read SD Cards from a trail cam. I purchased one from UGreen and it has almost no instructions. I can't get it to work. I did put the phone in OTG mode. I had to use an adapter from Micro USB to USB Type C. There is no indication that it is connecting. Any ideas?
If anyone has been able to do this on the 6T, even if it means buying a new adapter, let me know how.
Thanks
John
Do you have OTG storage enabled in system settings?
"OTG storage" is enabled. Are there any other OTG settings that also need to be set?
You need an OTG cable. That should work since that's how I transferred all of my photos from my micro SD card (in a card reader) to my 6T. I doubt directly plugging the card reader via adapter would work.
1. Buy a OTG microSDHC card reader.
2.Check the tipe of the files on card.
The unit is OTG but it has an micro USB fitting and I am using a micro USB to USB Type C adapter. Could that be the problem? I don't see how, the adapter should be straight through. I don't think it is a file issue, the 6T does not even see card. I might just try another reader.
use the app WiFi explorer, and you can transfer anything and everything wirelessly, via wifi..those files on your sd card need to be on another computer or somewhere they can be "seen"..
This one has been working great for me. I've used an older otg micro to A adapter with no problems before though. Could just be a faulty adapter on your end.
Yaotl, I can't figure out anything else but the reader. I think I will give the Anker reader you suggested a try.
Thanks for the help,
John
I purchased another reader. Works perfectly. Thanks for all the help. Especially, Yaotl.
