My galaxy a52s gets restarted on connecting my 2 TB transcend ext hard drive via otg cable. I tested it using an 8 GB flash drive and it worked fine. what should I do to prevent this restart ?
Try not connecting a hard drive to a phone for a start!
Seriously though, what makes you think connecting a thumb drive is comparable to connecting a hard drive? The power draw from the spin up will cause a massive drain on your battery, probably pulling down the voltage in the power rails that supply your phones hardware. Most hardware relies on there being at a steady voltage. This will cause fatal errors which may prompt the phone to abruptly shutdown to try and protect itself. I dread to think what damage this could do to the hardware if your doing it repeatedly. Data loss from the abrupt shutdowns is an immediate concern.
If you want data from the hard drive then connect it and your phone to a computer and use the computer to transfer the data.

I had xiaomi redmi note 7 before a52s and I used to connect my 2 TB hard drive to it and transfere data, I even connected dvd rom and it worked fine so I expected upgrading to a52s will give better experience

Not all phones are made equal. Why are you connecting it to a phone anyway? Curious minds want to know exactly what your trying to achieve.
The ability to connect a 2TB hard drive or dvd rom to your phone is great and ends the need to take your laptop with you every where.

All digital hardware relies on stable voltages and when you connect another device to your phone, the power draw can pull down those voltages and cause hardware errors so the phone forces a restart. I'm guessing the A52s has better hardware which draws more power itself. This may give it less tolerance to any power disruption from the attached hardware. I dont know the specs of the Xiaomi but my guess is that it has a better tolerance but its a guess and I can't be certain.

Phones have never been designed to have that kind of hardware attached to them. You could be doing serious damage if you continue. You're also unlikely to be covered under warranty in that scenario.
As for not taking your laptop with you, there are much better ways to achieve this. Pulling out a hard drive for a single file would seem cumbersome to me. Other ways to do this are cloud storage, using a thumb drive (which you said works fine), using an SD card (in a slot if you have one or use an OTG SD card reader) or just put them on the phone directly. If you're accessing multimedia files then you could consider a NAS and access it remotely. Thats what I do and work files go via the cloud. Neither of which require more than my phone itself.
I found the problem
Any usb device formated with NTFS file system
It's going the a52s to suddenly freezing and reboot
Try format the same usb device at fat32 or xfat and the problem will disappear
It's a bug in the firmware

Hey people,
Massive regret if this has already been covered to the point of solving somewhere but i just can't seem to find a clear solution to my problem.
One of the main reasons i opted for the Archos 101IT was because of the usb storage possibilities and i am sadly let down by the lack of functionality. After searching over XDA forums, ArchosFans and a few other forums i have gathered alot of information about the usb ports and was even suggested a kernel that will let me extend the power supplied to the port (Currently only 100mAh i believe?)
My problem is im already on a different kernel and don't wish to trade my perm root and higher overclock just so i can use the ports as they should already work anyway. I have a 16gb and 8 gb sandisk flash drive that i would love to use but sadly it dosn't work. I also found a conversation (can't seem to find it again) where a list of successfull usb host adapter cables was created and so believing it i went ahead and bought one and it still dosn't work.
I have no doubt in my mind it's probably something i am doing wrong and if someone could slap me in the right direction i would be very greatful.
Again, sorry if my attempt at searching has failed but despite the countless conversations on this topic the only solutions that i have come across are completely changing my kernel and a cable that didn't work!
Why is it so difficult to use damn storage? that's what the usb is there for am i wrong?!
Thanks in advance =]
your post doesn't make that much sense - Archos 70 and below requires usb host cable - the 10 already has a full size usb host port and sufficient power to run flash drives
Yes it does, but as i said it only powers up to 100 mAh without the usb power kernel and i believe it's the mini usb that powers higher normally. It's my understanding that on the other posts i have read a host cable from the Mini usb port is supposed to give you the option of powering a flash drive as the mini usb offers a greater power supply.
I hope this makes sense now, im just reporting what i'v gatherd viewing other peoples issues and im confused to hell about any real/ideal solutions and also as to why the bloody thing can't just work as advertised.
Maybe if we can't get any meantime solutions people could start listing what's working for them? If anything at all? As i have seen reports of success with flash drives on both the 101 and 70 and also people saying they had it working at one time then it's never worked since. All threads seem to end in either "Sold my archos" Or "Sent back to archos and and they replaced it but now it's still not working" Also i can see archos have no apparent interest in the complaints that people have made.
Cheers
The 100mA limit is only on the A70. The A101's full-size host post puts out about 450mA, but alot of devices have an initial spike higher than that in the initial plug in, just to charge the capacitors and enter active mode. The problem with the A101 is that it shuts down current when it spikes like that, resetting the device, and requiring another start-up cycle. No solution I know of yet. I've managed to find low-power devices, you can also use an in-line power supply usb cable.
Hi msticninja, cheers for your reply.
Sorry for my complete lack of electronics but im understanding that the flash drive's im using require more then the 450 just to power up and then they would use less?
Does inline mean a mains powered usb? as i have a 2 tb mains powred HD that i havnt tested yet but if it worked it would be a temp solution for home, but i would love to be able to use my flash drives (or any flashd drives) when on the go. Could you suggest some of the flash drives that have worked for you under that power spike?
Thanks!

Yes, after the power up they use less, but that initial spike causes the Archos to shut down the USB port.
Definitely try the mains powered HD just to test. Also, sometimes a really quick unplug and replug can help.
My Kingston Datatraveler G2 (16GB) works fine, and I have some generic 1GB sticks that work as well. It's kind of hit or miss, to be honest. If you have a local electronics store, they may have some that aren't packaged, so you could test them in-store.
http://cgi.ebay.co.uk/Kingston-16-G...660?pt=LH_DefaultDomain_3&hash=item19c64a7c54
Is that the right one? I sadly live about 20 miles away from any decent modern electronic store so id rather just buy one, if there's anything i have learned about flash drives as a producer, you can never have enough and also they will always sell on ebay for near the original price.
Thanks again =]
Also, Just plugged an old microsoft mouse into the large usb port, it lights up for a second then turns off with no real connection made.
Tried the same mouse in the smaller usb port with a host cable and nothing happens, could be the cable though.

I don't think the mini-usb operates in host mode on the A101, only on the A70. As for the mouse, I have had better luck with wireless mice. I think the wired ones, older "red" optical ones in particular, use more power than I expected.
I think I told you the wrong USB drive though. I'm just plugging it in to double check and it's not working. Let me look around and figure out what I was using.
Haha yeh it was a wired oiptical one, i assume the wireless ones work better as most are powered by battery and im guessing the usb reciever only needs a small ammount of power. Is that the correct usb on the ebay link though? If so i will buy it asap as im desperate for a working solution.
Thanks =]
Looking through logcat though, I don't see a power error. I think I formatted this [email protected] with NTFS, and it can't mount it. Give me a couple of minutes to test this out.
Yep, that's the problem. I just turned on NTFS support in UrukConfig and it mounted just fine. That link on eBay should work fine for you as long as you don't use NTFS without urukdroid.
Ok cool, is it having trouble recognising it now? Both mine are Fat32 i believe in order to switch between my mac and windows computers, let me know if it still works when you can =]
It's fine with NTFS enabled in UrukConfig. Fat32 should work by default. BTW, you can enable NTFS support on Mac pretty easily. If you have files bigger than 4GB, it's essential.
Haha i havnt had to cross that issue yet as i mostly work with sound samples around 2mb or under, but i will definately be correcting that soon. So is this the correct model before i purchase it? im excited now that you have re confirmed it! =]
http://cgi.ebay.co.uk/Kingston-16-G...660?pt=LH_DefaultDomain_3&hash=item19c64a7c54
Thanks for the info!
Yup, that's the one. It's a tiny bit big, but it's very fast.
Haha mate, size isnt an issue at all, aslong as the damn thing works im going to be a happy bunny. All i have been missing since buying this thing is the extra storage. My sd card is currently running whole OS as it was needed for 'perm root' and it also has 259 swapfile so that's the 8gb gone. If this usb storage works it means i'll finally be able to free up the enitre internal storage i've been clogging up with music and movie for some more apps.
Wish me luck =p thanks again! =]
That's why I like to run Android from the Internal Storage, so I can remove the Sdcard without shutting the tablet down.
Good luck!!
As soon as a decent root comes along where i can overclock to 1.2ghz on internal storage id be more then happy to run on internal, sadly the only one i know is archangels and it only works when in a wifi area =/ unless im mistaken then id gladly eat my words! =]

Technically you could, but it's a bit of an involved process. You do need the SDE installed though. Actually, I wonder if anyone's tried ardatdat's kernel recently with Uruk. It hasn't worked for a while, but there's been multiple beta updates since the last time I tried it.
That would be very tempting, im on sde anyways. Just a question, whats the 1 watt speaker about in ur sig? Is that a hack?

My speakers went out, because they're horribly overdriven, like most people's. I replaced them with 1 Watt Kobitone speakers that have a higher sensitivity, so it's louder at lower volume settings, and can go to a very high max volume without damaging the speakers. It's a simple replacement, but you have to open the case and solder in the new speakers.
About 3 months, I had some issues connecting my i605, rooted, running Jelly Beans Build 13 ROM to my PC (windows 8). It started with not being able to detect the phone at all, it then evolved into spotty charging, and the phone randomly going into "car mode" because from what I could tell, it thought it was docked. So I figured this was due to a faulty charging port, so I took it to a renowned shop and got the port replaced. Prior to getting it replaced charging got better and car mode (which was incredibly annoying because it caused many stutters and force closes from constantly turning on and off in quick succession) pretty much disappeared completely except for once. Since getting it repaired, charging has improved, and car mode has yet to appear, however it will not transfer files still. The PC is 50/50 with recognizing the device at all. Sometimes it will show up under "My computer" sometimes not. When it DOES I can explore the SD card (sandisk 64gb class 10) fine, and the phone onboard memory, but when I try transferring TO the phone I get an error that says, "The device is not responsive, or has been disconnected". Now when transferring from the card to my pc I get another error, but that error is also 50/50. I just tried it and can transfer from the card to my desktop fine, but not vice versa EVER. Anyone have similar issues or even better, a solution?
EDIT: I tried changing the ROM's extension to just .file and it moved over fine. This leads me to believe it for what ever reason just will not transfer .zips(seeing as that's all I've tried transferring, and .file worked fine).

You say Car Mode still hasn't started up since having it replaced? Could it be an issue with the replacement? I have replaced ports on plenty on phones, doing it myself not taking it to shops, and have never had this issue but it could be they didn't do a good job, didnt use enough solder to fill the PCB holes, and it isnt making contact the entire time.
It may also be a driver issue but to me it sounds like maybe the replacement isnt a quality replacement, maybe he didn't use enough or used to much solder, or there is another underlying problem with your phones MoBo that is causing this.

No, not having car mode is a GOOD thing. Car mode was giving me hell. It'd randomly at anytime just start turning on and off rapidly. The only remaining issue is the transferring of .zip files.

Have you tried troubleshooting this issue using just the micro sd card in a card reader?
It could be that windows 8 hasn't the proper drivers to interface with the phone.
Also, a cheap workaround could be to transfer the zip files to a flash drive and
use an otg cable to connect flash drive to the phone for transfer there. If the zips transfer that way I would suspect
the windows 8 pc samsung drivers to be the culprit. After considering all the facts, though, you might want to return your phone for a port repair again. My curiosity got the better of me. Does it charge with the factory wall charger with no interrupts?

You mean put the micro SD into an adapter to make it a regular SD card and then try that? If that's what you're talking about I've tried that too, for what ever reason that card (64gb sandisk class 10) is read only. I can't write to that card. Maybe its the formatting or something but if I recall right I researched why I couldn't write to it months ago, and though it's very fuzzy I feel like my research amounted to: "you're **** out of luck". Trying with an OTG might work, but I'd have to get an OTG cable first. Thing is it USED to transfer .zips. That's how I rooted and placed ROMs on my phone. It's only recently after all this charging port problems that transferring became an issue. I thought it was simply because the port became loose and the "connectors" (excuse my lack of hardware-speak) were touching and then jiggling during charging or unplugging the phone or whatever caused the port to lose connection with the rest of the phone. So I blamed a defective port for all my issues and decided to replace it. Now since it's been replaced all past issues are gone, except this transfer issue. And to answer your final question, it did not prior to the repair, it does now from what I've seen.
Hey everyone, I have a Samsung Galaxy SIII (LTE Version) and no matter how hard I try I can't get it to solidly connect to my computer!
What happens whenever I plug the Galaxy SIII into my PC (Windows 8) is a follows:
I hear the device connected sound from my PC and the charging indication from my SIII. So far so good, but most of the time when I go to "My Computer" the phone isn't listed anywhere. After a couple of times plugging the USB cable in and out it shows up on the PC, but almost instantly after being listed I can hear the device disconnected sound and the window closes. If I move the cable for the SIII even a tiny bit I can hear the device connected sound almost instantly followed by the device disconnected sound and a message from Windows telling me that the USB device malfunctioned.
This makes the task of copying photos or movies to and from the device near enough impossible. The phone is only a few months old and is completely unmodified! The USB cable is also the stock out-of-the-box one. This doesn't seem to be a new issue either! It's been happening almost out of the box but I assumed it was down to drivers (which were updated but made no change) and now it's starting to annoy me very much!
Any help would be much appreciated

Beware if you dont know already, factory reset wipes your internal sd card. Maybe use dropbox to auto upload all your photos before you get to that stage.

Alright, so I went digging in the cupboard and found the cable from my old Xperia Play. Upon using that as opposed to the one Samsung shipped with the phone, the connection issues seem to have vanished. (I'll update here if they return)
I suppose this goes to show badly made the stock Samsung cables are which is quite a shock considering Samsung expect people to rely on them.
The cables are crap. The s3 has built in stability detection. If connection unstable with cable, lowers charge to 100mA.
Almost all the "slow charging" threads are down to crap sammy cable

Ha! I was also suffering from really slow charging with that cable! Again though, thank you for your help
I had the same issue, new cable did the trick!
I dont really know where this goes...General or Troubleshooting. Anyways, be very careful when using OTG. I dont know if it was because I did not hook power to the cable, or something else, but I destroyed a 32GB sdcard (which had years of stuff on it - and I mean destroyed...no file recovery possible and I tried multiple times) and screwed up an ipod classic. I had the classic on rockbox and was transferring music from my sdcard to the ipod classic and after I moved 1 folder, both the phone and the ipod classic reset. The ipod would not work until I flashed apples os on it and the phone just rebooted. I found out later that my sdcard was not working and thats when i went into panic mode only to realize after days of working with it that it was trash. So, just a warning.
On another note, be careful with editing settings.db. Soft bricked my phone with that one. Always, when you have made changes, copy a new settings.db to edit and dont use one created days ago...what a fun time I have had with this device

Maybe you have a bad OTG cable?
I'm always plugging in an external reader and thumbdrives to transfer stuff. Usually daily. Not 1 issue.
(I have the "official" Samsung OTG cable)
I have never had a single issue with my OTG and flash drives, card readers etc and I have both 2.0 and 3.0 cables. I don't think that even a bad cable would cause data loss or your card to be "destroyed" Sounds like it had to be something else
I think my main issue is it was an ipod classic which uses a lot of power (only know because the RPi cant power it without a powered hub) and the fact I did not power the OTG cable, basically just plugged the ipod cable in one end and the other end into the phone - no power. It rebooted during a move process when I was moving a folder off sd to ipod. Rockbox isn't 100% for the classic either, but it did work. Just a general watch out for people not supplying power to the cable, or maybe I am the only one who doesnt plug the other end in to something. Flash drives and the like dont require a whole lot of power that Ive seen and Ive used them on the EVO 3D without power.
Just wanted to put out a warning to anyone who tries to hook up an ipod without powering the OTG cable - DONT DO IT! LOL.
Ill look into getting an official OTG cable soon and stop using this one as you could be right, though Ive never had issue before. I think I'm going to try getting a 3.0 cable.
In your case. Maybe android and samsung is just allergic to apple products. Hahaha

Hi I have an LG Gpad X8.0 v520. It has a full size USB A port. I used to use a Kingston USB 64gb with it. But then one day suddenly it stopped working. The USB was not being detected nor any other device such as usb dongle for a wireless controller. They don't get detected even when I connect using the charging micro-B port with an OTG converter. Sometimes it works perfectly and then it works for like a day maybe two then stops working again. I have no idea what triggers it but the not working times are much more than the working times. My suspicion is that it has something to do with charging the device. Perhaps media is disabled during charging and it doesn't get reenabled. But I don't have the expertise to diagnose the problem I was hoping someone could help. I have already tried restarting every time and the USB devices all work perfectly on their own.
Any help or advice would be greatly appreciated.
I am not sure if your device has a mechanical issue ( contacts or pins inside connector? ) or only software.
i have a handful of V521's and some are fast when detecting USB , other take a min or two. whenever the STOCK rom/firmware hangs or does not populate with a new usb device, i power down the device after plugging it into charger. ( this isn't fast..) when its completely in stand-by , waiting to be turned on, wait for the battery icon to pop up on the screen ( charging level / status ). the battery icon that pop's up indicates a hardware controlled charging status. insert your USB and then power ON your tablet. (note: A 1tb SSD - it takes about 9 minutes to populate under LG's file explorer after this) This should work, but from this point on, use the EJECT option ( software ) before removing the device.
-i can confirm on 4 separate V521's that if the battery is 20% or LESS, USB devices won't always work. i never found the perfect tablet charge level, but 80% seems to have no issues for me.
The FACTORY rom only likes certain partition tables, so if your USB drive or thumb drive gets messed up, check it in a linux device. (it ALSO doesn't seem to like more than 2 partitions PER usb device)
-the V521 will see a 4TB SATA SSD in a usb enclosure, but don't expect it to instantly appear.
i use a dedicated LG-v521 tablet , to transfer files wirelessly with my SHIELD TV's.
-last note for ANYONE having issues, try a WOODEN TOOTHPICK if the USB connectors are pushed down or need re-bending. I like to smash a toothpick end with a flat hammer, dip the toothpick in some super thin superglue (CA) , let it dry, and it becomes the perfect contact adjustment tool.
-DE-OX-IT contact cleaner ALSO works wonders, just kind of pricey for a one time fix. ( this stuff is amazing, but ALWAYS WIPE IT OFF after using it, otherwise it continues to remove oxidation and makes a mess )
-there is a current limit set for the USB port on this tablet, and if the USB you try, bumps it or exceeds it, i'll start the process over again with restrictions ( lower power levels ) until a valid handshake.

I am having this issue as well. No noticeable physical damage. I factory reset the device too. The usb provides power just fine. But there is no data exchange. I am using a CarPlay dongle with it and it worked all day yesterday then it suddenly didn’t work. At first I thought it was because I drained the battery to 20%. So I charged it and the issue still persists. Any ideas?

Tried multiple dongles too. Tired usb thumb drives and they don’t detect either.
- does the tablet have WIFI/CELL signal ?
- did you try power cycling with and then WITHOUT the USB device inserted ?
-is the battery near the end of life, IE: old lipo EVEN IF CHARGED will cause nightmares..( changed 7 tablets batteries over weird issues )
- You confirm the USB port still provides power when needed ? (ill post a pic)
Stock ROM? ROOTED?
-whatever device you plug in, does the STOCK FILE EXPLORER show anything ?
-i turned off AUDIO ROUTING USB under DEV settings, not sure if this matters ?
-Conflicting APPS trying to all see the same port ? ( ES FILE EXPLORER gave me issues )
-its possible if you plugged in a USB DEVICE that pulled too much power, the regulating IC failed?
-ODD one here, but did you wait a bit, to see if it populated ?
below is a 8TB drive in a cheap china case, works great, just need to wait about 10 mins for it to populate.
(i use a dedicated V521 for compressing files , then moving them to HARD DRIVES)
- not sure what MICRO SD card everyone uses, but i personaly like the SANSDISK EXTREME PRO ( BLACK RED ) just wish they weren't so expensive. - the V521 will move files from the MICRO SD to HDD at about 50-70MBS
