I've had a Galaxy Tab A 10.1 for over a year now and get the most use out of it by connecting a thumb drive via the usb connection (for viewing pdf files). It's worked great until a few days ago.
After connecting as usual there appeared a message at the bottom "something something disconnected" (the "something something" being I don't remember exactly what and the message disappeared before I could see) and now the usb/connection doesn't show up in the "My Files" window (just the "internal storage" and "sd" indicators, whereas before I got the additional thumb drive designation).
I've tried two different utg connectors, no good. I've checked the thumb drive in my pc, it's fine. I've tried connecting the tablet to my pc via the usb, it doesn't show up at all. I can still move files between my pc and the tablet via wifi but I want my usb connectivity back!! I suspect the connection the utg plugs into.
Also, (I'm not sure if this is a separate issue or related) battery recharge seems to take much longer ... is this a sign of the tablet getting old? I could understand if it was 3 years+ but 1 year??!!
Thanks for any help or ideas as how to fix this!

I'm assuming you are using an OTG cable to USB Drive or a micro USB drive right? In other words the part you plug into you Tab is a micro USB and not Type-C USB? If it is micro USB and not Type-C try this ... https://www.youtube.com/watch?v=sGGdsMsK3VU. If it doesn't work the pins inside are probably damage and you need to replace the OTG cable or the drive, what ever you are using. If Type-C USB same thing. Needs replacing. Those pins ware out over time and use. Thats my best guess with out pics and further information.
Edit: Found this Image of what damaged micro USB pins look like, the damaged ones being on the right...

Yes, I'm using a usb (to take the thumb drive) to micro usb connector. I suspect it's not a connector issue as I tried three separate connectors and none showed a connection to the tablet (i.e. the thumb drive did not show in the "My Files" page as it used to) ... all the pins on all 3 connectors look good, the fit into the tablet port is tight, no looseness. I've looked closer at the micro usb port on the tablet and I'm beginning to suspect that's the issue as a receiving contact on the outer edge seems to be damaged (possibly) ..
Thanks for the reply and the link to the Youtube video!

No Problem, I've never had a female Micro USB port go bad on me , but have heard of it happening. A good tug in the wrong direction I suppose could pull the solder connections apart or maybe even damage the innards. Is the Tablet taking a charge? I'm a little confused to actuality what part your referring too. Here is an image explaining what the different types of USB's I think you are using. Tell me what color circle you think is damaged. Or if you are using something else entirely different.

Can anyone confirm that the Universal does not have USB host. Most places just say no but there isn't really any hard evidence of it. I know the processor supports it but did they put in the necessary circuitry for it? Whats strange is that the Universal's miniUSB port is the same as my Sharp Zaurus's miniUSB port and my USB host adapter fits in. Does not fit into normal miniUSB ports. Just the Zaurus which had USB host and the HTC Universal. Just seemed a bit odd to me. I tried it of course and did not do anything.
I'll experiment with this further and check that image of the mainboard closely.
everybody who posted about it in this forum reported it to not support host
connector means nothing all htc devices since the universal have had the same connector
heck these days they are talking about making it the std connector for all phones nokia and the likes too
This all hinges on the connector, and the hardware used to drive the connector. The Universal(and indedd, all mobile devices) use mini-USB connectors, which do NOT incorporate a host control circuit. This means that, since USB uses a protocol that might be termed as "Speak when spoken to", your device can answer the computer when it asks, it can NOT ask another device to speak to it.
To sum it up, you can't connect a pendrive to your PDA, but you can connect it to your computer, precisely because of the lack of the USB host controller unit.
Hope this cleared it up for you...
Cheers
This is not what I meant. I'm talking about a specific type of miniUSB connector.
And in the recent announcement to make a standard cell phone connector, they chose microUSB.
This is what I mean.

HTC Universal's miniUSB port.
A normal miniUSB port.
My miniUSB -> USB host adapter from my Sharp Zaurus fits into only the Zaurus and the HTC Universal. Doesn't do anything in the HTC Universal though.
Not possible.
If you check on the internals, you will find that there is no power output to the usb port in anyway. so, its a hardware limitation and there is no way it will support hosting, be rest assured!

I found a thread in the German PPCWelt.info forum where several people say that there MDA Pro supported USB host, with a special driver:
http://www.ppc-welt.info/community/showthread.php?t=74113&highlight=mda+pro+usb+host
I don't know how reliable this is (not every USB client can act as a USB host because of different hardware AND software), but perhaps you want to try it.
Alex
EDIT: They also say that your USB device needs a power supply because the MDA can't do that (external hub). Other people even say that without such a power supply your MDA could be damaged. This Engadget article is also mentioned:

I know that. I just wanted to know if the hardware was there for it thats all.
the hardware maybe there deep inside the cpu but the pcb lanes where maybe support chips were never connected rendering it absent
can some of german guys test it and report it to this thread.?>
Hello,
I wanted to notify you guys about something that we (my sister and I) accidently discovered. After I gave my phone to her (I get a new one) I installed NoData to prevent extra costs. I forgot to put the USB cable back into the charger, and somehow she got her hands on an Mini-USB cable and plugged it in. The day after, when I woke up, I was surprised that this cable did exactly the same as the original does. I've tested it with the PC also.
So for all users out here; you can use Mini-USB as well.
I'm sorry if this has been discovered already.
Regards,
NLCJ
EDIT:
I'm not totally sure whether this USB type is called Mini-USB, but I found it using Google, so I guess it is.

Het warm water opnieuw uitgevonden? Neen het is al langer bekend het noemt een usb ext aansluiting van htc, dit is een mini usb met extra audioconnectie.
Yep thats been seen before, HTC uses ext-usb, which is just mini-usb with some added pins.
neocivis basically said the same thing, but in dutch

Here is connection of that cable.
Am i the only one who cant use a normal mini-usb cable for data transfer? It charges, but when its connected to a pc i cant start usb-transfer. Is this normal?

No, this is not normal. Additional pins only affect the audio.
Perhaps try a different cable.
ye known for a while thouht it was obvious so didnt bother posting it....
PS3
Yes, it is possible. I am using PS3 cable, usually used for charge controller. It is possible to use another USB for phone, but isn´t possible to use HTC cable in another USB "holes"
I try mini usb cable it's work with active sync, disk drive & charger
Thank you brother

I know this is a little old but for those who have the same problem, there are differences in USB cables, some are for charging only and don't include a wire for sync; you need to make sure the cable you are using is sync capable.
I know there was a lot of confusion when details were first released on multiple sites including engadget but it looks like the USB adapter will work for the 10.1 check there web site for details. they are out and for sale.
on the bottom of the page it says goes great with.. and youll see all 10.1 devices

I think the confusion was with the SD adapter. It said "8.9 only" on Samsung CTIA slide. Hopefully they'll have one.
Anyone else think it's a bit of a con to release these all as separate adapters (i.e. if you want HDMI then that's an adapter, USB is another adapter, SD card slot is another adapter). I think Samsung could have put all those connections into a single adapter. Also, it's weird how the HDMi adapter has a little bit of cable to give some flex in the connection where as the USB adapter is just a single block.

Considering how big these adapters are, shame they couldn't put USB and SD or USB and HDMI or all three on a single adapter.
Even the media port doesn't appear to have HDMI out it, looks like it has another 30 pin port on the back and you have to buy the HDMI adapter for that.
All these adapters, all being sold separately is gonna get quite pricey too. Even Apple was compassionate enough to sell the USB and SD adapter in a single kit for $30 (saving $10 over buying each separately for $20).
PS. Though I imagine some third party might save us and come up with some adapter that combines multiple things together. They've done it with the iPad adapters.
Ugh these accessories are such a rip off. $19.99 for the damned additional data cable?! The hdmi cable port is also $29.99, just absolutely ridiculous. I'll prob eventually snag one regardless... :-/

Most definitely. This tablet is going to have so much aftermarket accessory support, we won't know where to begin.

With the exception of jump drives, most USB devices have their own cable.
Does anyone know if the HDMI converter works with the 7" Tab?
You guys are lucky to see accessories, the UK mob don't even have a clue about the 10.1
$40 for HDMI!?! Are they ****ing serious?! Who do they think they are? Apple?!
A bit more on this....

Hi, I am relatively new to digital 'prototyping' so USB protocols and almost everything digital is new to me.
The long and short of my question is, if I plugged a standard USB flash drive into an OTG adapter, and then plugged all that into a micro USB to standard USB (which I doubt actually exists) and plugged that combo into a PC, would I be able to access the flash drive? How exactly do OTG devices VS 'regular' USB devices work?
From the circuit schematics I've studied, it appears that the only difference between a standard USB and OTG interface is a bridge across pins 4 and 5. So how would this affect plugging said OTG device into a PC?
Yes. Long as your device supports it.

That is my $2 otg adapter...I plug in external HDD...flash drives ...keyboard... Mouse...PlayStation controller..
.tech you can make your own BC the pin config is only diff.

So if I directly hardmodded a standard USB flash drive with a micro USB plug, bridging pins 4 and 5 to make the device OTG-ready, if I plugged that now hardmodded flash drive into a micro USB (female) to USB A (male) the PC would still read the drive as a standard flash drive?
This makes sense because apparently on the micro-usb interface, pin 4 is "sense"?

Thank you for your assistance.
Yes/no.
The standard (full-size) USB A and B connectors only have 4 contacts and 4 conductors.
The ID pin (#4) is only on USB mini and micro connectors.
You need to signal your cell phone to go into host mode.
That means that the connector plugged directly into the cell phone has to have a grounded pin #4.
Pin #4 is never carried over the cable.
In short, you need an OTG adapter plugged into your cell phone.
Modding other parts of the cable or the USB device you are using won't do anything.
You can (as I have done) take a razor to the connector that plugs into your cell phone,
take the connector apart and solder a wire from pin #4 to ground.
I recently bought a USB 3.0 Data cable and it seems it has problems connecting this way to my computer... Yes, I'm connecting the USB 3.0 to the right port (the color blue one), I already try the restart, the blow a bit in the cable :silly: and nothing happens.
The very first time I thick the option to connect as USB 3.0 I get a message saying "UNABLE TO CONNECT DEVICE AS USB 3.0". See attachments for my info of the phone.
Any help will be appreciated so much

Check your PC settings to make sure the USB port on your PC is 3.0: open Device Manager > USB Root Hub > Properties > Details > Hardware Ids and make sure the Value = USB\ROOT_HUB30

Everything seems in order. The problem is that I can connect USB 3.0 HDD and everything works great. But the Galaxy S5 shows that error.
Hi, was this ever resolved? I also have a 900H but don't even get any USB 3.0 option or notification.....I think the cable I bought might be a scam
have u tried with another usb port?
cauze i had had the same issue and i tried to another and worked..
Here is what happens and I expect should happen.
IF I plugin the phone to a usb3 port it is detected by windows and in the system tray I get a popup alerting me I plugged in a usb3 device into a usb2 port so it wont run as fast as possible.
On the phone notification tray it will show usb connected in media mode, if I tap that I can choose between usb2 media mode, ptp mode and usb3 media mode.
This is if I use a usb3 cable. I have 2 usb3 cables, one is official samsung, another is different brand but still works.
If I use my S5 dock, (this dock claims to be USB3 and comes with a usb3 cable as well as using usb3 connectors) the same thing happens on windows, it alerts me I have plugged in a usb3 device to a usb2 port however I have no option to change to usb3 on the phone, based on this I believe my dock to be faulty and actually only usb2.
So in my opinion if you get no usb3 option on the phone it means either the cable or the port on the pc can only use usb2. There is also a chance of driver problems on the pc, I had to update my intel usb drivers to get usb3 working properly.
Use belkin usb 3.0 which Ian using it. No usb 3.0 displays. It charges good and also does good speed offile transfer .
It appears the cable I bought was the culprit....fake cable even though it had all nice samsung logos and numberings....
I took the cable of my hdd which is a toshiba 3.0 1TB hdd and it worked with that. NOW I do get the USB 3.0 notification...
I really want to use the samsung cable since it will be like 2 feet longer than the hdd cable but how to spot the fake ones from the good ones when buying??
