Dock USB problems - Asus Eee Pad Transformer Prime

i just received my dock today and plugged in my USB flash drive and found out that it did not work. There was no power going to the flash drive at all. As soon as/ plugged in the keyboard, I downloaded two firmware updates and there was still no USB power. Anyone have this problem? i also rebooted after the update.

same here, my sandisk cruzer doesn't work with the dock either. as soon as i plug it in, i get a short "preparing usb device" notification, but it immediately disappears and then nothing happens.
the drive must be powered though as it lights up. usb hard disks with their own power supply get recognized without a problem..

i found out that it work if i reboot my tablet with the usb plugged in. it works but that is very inconvenient.

Same problem with my sandisk cruzer. Tried to plug it in an usb hub and it worked instantly. Maybe sandisk related problem. Reboot also worked for me.

I had the same problem with my kindle and solved it by rebooting it with the kindle connected to it...
Hope they fix it... It's a big annoyance to have to reboot the tablet to get the USB working....

same issue here
however better workaround than rebooting , go into settings storage and under
usbdisk1 there should be an option to mount external storage..
That worked for me , still annoying we have to do this but better than rebooting..
well it sorta works , after i mounted and checked i could access files i came down and made this post , after that i went back to the tablet and screen had turned off , on resume it had unmounted it so had to mount it again..

I had no problem with Patriot 32gb Rage XT.

I have a 16gb sandisk cruzer "blade", and it works fine... I plug it in, it "prepares" the external storage, and then mounts it ready for use.
So, it seems it depends on the flash drive... I have a few various thumb drives kicking around, I'll give them each a whirl and report back.

I had the same problem when i got mine in!

when i saw the "mount external storage" i facepalmed, literally.(OF COURSE IT ISNT WORKING ITS NOT MOUNTED -__-)
its not the usb not working people, its the external storage not auto mounting.
any app that can do this ?
just got my sandisk cruzer working, sandisk isnt the problem, auto mounting is

[Q] Problem with Archos 101 USB port and external HHD

I have looked around on here and cant find an answer....
My friend just bought a A101. He used a external hard drive once (Seagate Portable Drive, 500GB) After he connected it the first time, it has never worked since....
Does anyone know what would cause this, or how to fix it? He even has already reformatted both and did a factory reset on the A101...
Thanks for any help
Hi,
that happened some of us when we upgraded to FM 2.071.
I called Archos and advised me to send it for repair.
Regards.
Javier-
Did they say they would charge you for it? Have you sent it in yet or received it back? Just ordered a Seagate 500gb HD and now I'm a little worried.

I had the same issue, sent it in for repair, came back faster then ever, but now looking at same problem
This sounds more like an underpowered usb port, rather than a failed usb port.
The usb port only supplies 200ma power, most hdd require 500ma, especially if you are powering said hdd off the port.
I suggest installing SDE, then installing UrukDroid 1.0, then look in the UrukDriod dev forum for Sibere's V10 kernel - it raises the ma from 200 to 500, but even then, it's not a 'complete' fix - the port seems to share power with the display.
Good luck!
Question:
Has the Seagate 500GB external portable HDD worked properly before it was connected to the A101IT.... like were there any problems whatsoever with it being connected to a laptop/desktop at all??
If the portable HDD HAS worked then you have a guaranteed FUBAR USB port, period! I actually had the same problem and I thought the problem lied with my Western Digital 500GB external portable USB-powered HDD because it was working with my A101IT for a long time then one day my A101IT couldn't find my WD HDD when it was connected. I then disconnected it from my A101IT and found that when I reconnected my WD HDD back to my laptop that there really was no problem with my WD HDD at all, it was the USB port on the A101IT! Also you can plug a thumb drive/usb stick with like 1 GB+ that has stuff like documents, movies, music, etcetera on it and if the information on the thumb drive still doesn't come up after you have connected it to your A101IT the problem is a definite A101IT USB Port problem.
P.S. - By the way, reformatting the entire A101IT AND upgrading/downgrading to a newer/older firmware will also not work.

Can't read SD cards from dock

Hello everyone,
I noticed that after last update, my dock doesn't detect any SD card I place in and this is quite scaring me, since I don't really want to send the dock back to ASUS... do you think a full wipe could make this fix?
I tried with a Cl.10 16GB SD by Samsung and a Mediacom 4GB (don't know the class) but my tablet just says that available space is 0,0 GB and it can't unmount the card...
What do you think about it?
Tiwiz
I have sent my dock in twice for an RMA because both my USB and SD card are not detected by my Prime. Sent back twice and I still can't see anything plugged into these ports.
Just did a factory reset on my Prime and still no luck. I guess another RMA and see if I can send both dock and tablet in together to let them see that the ports are not being detected?
Coincidentally, yesterday I tried to read a micro SD card via an adapter card on the dock to copy some music onto the micro SD card in my tablet. It shows the card in ES File Explorer or the Asus File Manager, but when you browse, it displays an empty card?!? Hopefully its a driver issue, rather than a hardware fault...
After reading the posts I thought I'd try my keyboard dock ports and I plugged in a 160gb hard drive to the USB. It took a few seconds to read it and then I could open it from the status bar or the stock file manager. Was pretty easy.
I plugged in my Atrix phone and that doesn't do anything. Thought maybe it might charge or something. Didn't try the SD slot.
I think you're going to have to do the dreaded RMA and I wish you luck for a speedy turnaround.

same here. after reading this thread i decided to test out my dock sd card slot. it works perfectly. i can find the card in asus file manager and i can find it using 3rd. party file explorers also, like astro.
I actually just tried out the SD card slot on my dock last night for the first time. The first time it detected the card immediately. It showed two of the SD card icons (one in the tab, one in the dock.) After I took the card out of the dock, put some other files on it and plugged it back in, it didn't recognize it. I tried searching for it with ES explorer and it wasn't there. When I ejected it, ES prompted me that the card was empty...... weird. I then plugged the card into the tablet and it worked fine. Plugged that same card back into the dock, but was not prompted that it was being prepared, but all of my file explorers showed it there. Now, I no longer have the two icons in the tray. It only shows one when I have two cards plugged in. Veeeerrrryyyyy glitchy
---------- Post added at 09:25 PM ---------- Previous post was at 09:18 PM ----------
and just like that, i once again am showing both sd card icons in the tray. i didnt even do anything. just appeared while i was reading other posts.
the prime is reading my mind.....
Aye, it's very temperamental. But it does work, for me.

jsjames - I have had this exact problem. I have also sent my dock in twice, and it still does not work. And I've tried the factory reset. Did you end up sending in your dock and tablet together? Did it work?

Yes, I sent both in and I got them back about 20 days later working again. Not sure what they did, but the card readers work again.
However, the glass on my tablet is popping up a little bit on the right side. Not sure if they did it or it's just the tablet. I just keep pushing it down and it sticks for a while. Must be double sided tape under it?

How to connect to PC

Is there anything I am missing here? I cannot for the life of me get my Prime to show up as an external storage device. Also it will not charge when connected to my PC. Charges just fine with the regular charger.
should show up as a MTP device. I wish i could have it as an external storage device, im interested in this as well. Anyone know how to do it?

Incorrect, the prime charges fine over USB, as long as it is USB 3, my laptop charges the prime just fine.
USB 2 and previous do not output the power needed to charge the prime, the prime needs at least 11.1 volts to charge, the adapter puts out 15 when connected to a USB 3 cord, but a perfect 5 volts when connected to a USB 2 cord, so your phone is fine to charge on that charger as well.
As for connecting to the computer, check out Samba network fileshare.
It works perfectly for browsing, there is even a hack to allow you to browse your root directory as well if you have root.
However natively it only connects as a media device.
Thanks for the replies!
Well that sucks big time.. transferring movies over WiFi takes for eeeeeeeeeeever. Can't believe it's not supported as external file storage. Oh well.. get my dock tomorrow. Should simplify things I hope.
I guess you can't connect the dock to a PC to transfer either?
That is correct, the dock adds no special abilities.
Use an SD card adapter, put the car in your computer and transfer that way, as fast as it can possibly get.
Does any of the custom ROM's allow the device to be recognized as a storage device? This would actually be worth it for me to unlock my boot loader.

My TF201 is recognized as media device named Transformer Prime TF201 in Windows Explorer and I can manage the memory storage without problem.
Is the right driver installed on your pc?
You can also use AirDroid (free on Play Store) to manage your files. But it's through Wi-fi.
Btw: my TF201 is rooted. I don't know if it make a difference.
I second the advice about charging. No charge when i plug to my pc (USB2), charging when plugged to my notebook (USB3)
Usb3? Sure, if you got it.

That's not true. Like pnoire stated, you can get your TF201 to be recognized as a media storage device. And also like you, when I first tried to connect my new TF201 to my pc, it wasn't even detected as plugged in. After a few tries, I figured maybe that USB port was bad as I've known it be kind of bad from time to time. So I tried a different port. This time my pc detected it as being connected but then it was listed as "Unknown device" under Device Manager. After some Googling and searching the forums, I ran across the thread about the Universal Naked Driver Beta in the development forum and it mentioning that some USB drivers for some Android devices conflicting with others. Since I had installed the Samsung USB drivers for my Samsung phone, I thought maybe that's what was causing the problem. I proceeded to uninstall the Samsung USB drivers and then retried connecting my TF201. Sure enough, my PC detected it again and proceeded automatically install the drivers it found from searching the internet and VOILA! My TF201 is now a working media storage device displaying both the internal sdcard and my microSD card I put in it.
Long story short, try uninstalling any other Android USB drivers for any other Android devices you might've installed earlier. Sometimes the only way of uninstalling the drivers is to first connect that device to your PC and uninstalling the drivers while viewing the device in Device Manager.
I'm not entirely sure how much help this will be but I had the exact same problem as the OP when I got my prime 2 months ago. I looked everywhere and found a solution although unfortunately I couldn't find the solution again after just trying to link you to it. Go to the device manager and find your prime listed as an MTP device. right click and go to properties. I'm pretty fuzzy on this so bear with me. You should have an option to select driver from a list. click that option and you'll have a ton a driver options to select. Look for the driver called something like "Universal MTP..." and install that. I was able to browse all internal storage on my prime after I did that and it would auto-connect like any other USB device once I plugged in the prime there after. Good luck!
I don't know if this will help or not, but when I tried with mine it wasn't recognized either. So after trying a couple of times I tried wiggling the usb end of the cable going into the PC and bingo it shows up as "Transformer Prime TF201" and I can transfer files no problem.
Hope this helps.

I am confused. My normal state. Do you use the cable that is the charger cable or do you need a micro USB cable.
Thanks.

The charger cable that came with the Prime.
I had this problem with MTP drivers being screwed up on my computer and several devices wouldn't work correctly.
I Google the MTP driver error I was getting on connection and in device manager and found it was due to a registry problem. If you're having that problem I can find the guide again and send it to you.

Atrix charging issues

My phone isn't charging properly. It isn't recognizing that it's plugged in although I've tried different outlets and 2 different chargers that do work. I have some luck charging it while plugged into the Wii or ps3 USB ports.
Anyone else experienced this or know what can be done?

I had a issue similar to that once. I have 3 cords. Computer, A/C, Car (all worked and didnt work, I did the common thing which was pull battery and reset but of course it was a temp fix. I ended up killing the battery on purpose and using my wifes phone and charged it on her's (same phone) and also updated my rom on mine and its worked fine since. So I dont know it if was the Rom or what but ive never had a issue since I changed the rom. I dont think my wifes phone really did anything but I put it here in case.
What ROM are you using now and what were you using before.
I am using MIUI v4 2.8.10 and my phone is charging fine (from the laptop and the wall outlet). When I connect it to my laptop it does not mount the SD card (I have a SD card). It does no mount the internal memory neither the SD card.
This is driving me crazy. Any suggestions ?

[Q] GS2 OTG Problem or...?

Hello guys,
I bought a converted GS2, it was a M250S version, it's now converted to i9100.
I bought a OTG cable to connect pen drives and keyboards, and all that. The problem is, if I connect the cable, it says "USB Connector plugged in" (Something like that I'm translating it from Portuguese). I then procede to insert a pen drive or keyboard or anything else and nothing happens, I can't find the PEN DRIVE mounted on any place! Tried a lot of programs from the market, checked other topics and discussions, nothing helps my situation, why? Is there a common problem on GS2 or am I missing something?
I had NEATROM! Today I flashed OMEGA. All of them, full versions, and still OTG isn't working.
The real thing that bothers me is, the cable must be alright correct? Because the phone detects it, it only doesn't detect what I attach to it!
PS: If I insert a flashdrive with a LED light indicator, the LED normally blinks when its connected, it should blink as well when I conect it to the phone correct? It does nothing
I hope this has a easy solution, just went from an iPhone 4S to this GS2 because I tought it could help me at work, where I need to download files and transfer them into pen drives to use on other computers that down have internet access! The idea sounded awesome, but it isn't working

try connecting the pen drive to the cable first and then plug the cable into the phone. Go to settings>storage and see whether your pen drive is shown there as usb storage. If it shows then your otg works fine. Use root explorer and go to storage folder. Then you should have a folder called usb disk. That is your pen drive. If this does not work try connecting a usb mouse and see whether your otg cable works

Hmmm might it have something to do with the fact that the phone is partitioned? 2GB for the system and the rest appears under USB Storage, and then again I have a microSD card wich appears under SD Card, all these shown in Settings - Storage
BTW as said, should the leds get on ?!
Anyone with the same problem? Am I missing something?

Well make sure that the pendrive you're using is formatted FAT32 and not NTFS(for ntfs you'll need to use another app if you wanna mount it)..
Whenever a pendrive gets mounted on your phone...its mounted on directory Internal Memory>usbstorage if you're running stock...and shows up just below your mmc in settings>storage..
Also as soon as it gets mounted, in notification panel you get press to unmount...for unmounting the device..
If you still have problem you can use stickmount...
LED's of pendrive will get lit...
Press Thanx if i helped..

I connected a pen drive formatted as fat32, and a USB mouse (IE 3.0), the pen drive led doesn't light up, but as soon as I connect the OTG cabble it says USB Connector Plugged In (something like that I'm translating it from Portuguese) so the cable works I guess? but nothing connected to it does?

Would a mouse work in a stock Nexus 7? Either way if the LASER doesn't light up then it's the cable fault right?
I can test it in a new Nexus 7 with stock ROM 4.2.1 later or tomorrow.
