good afternoon,
I hope some one can help me.
about 2 weeks ao i installed the revolution Rom on my asus eee pad transformer.
But now the USB ports of my dckingstation are not beiing regonized any more when i put a usb stick or something in it.
Any one that has an solution for it?
Restart your tablet.
For me restarting after inserting sticks or cards brings them up. You need to reboot each time. Will show both usb and SD if all inserted and then you reboot.

I have still got the problem.
I have tried a usb mounting app but that app doesn't find my usbstick or my usb harddrive.

Not 100 percent sure but i beleive someone said that you need to boot the device with the usb plugged in for it to recognize some drives?

It should be listed as usbdrive using your favorite file manager. Usually under
...
...
sdcard
sdcard2
usbdrive
Its not like windows. It doesn't pop up with a window when you plug it in. Flash drive must be formatted fat32. Android doesn't like ntfs

I do see the USB drive bit it's always empty. USB drive is fat32 formatted.
Using a USB mouse works great. I don't get a popup which notifies me about a connected usb drive like my archos 101 did.
Did a little discovery:
When connecting the tab to pc with a usb cable only then a "mount usb" message pops up.
Then a usb drive will work.
Now how do i get the gtab to mount the usb drive ?
I don't think any of these roms are gonna give you a popup when you load a usb drive. I just plugged one in on tnt 3.1 and it reads it thru file manager. I was on vegan beta4 and did the same thing yesterday
Edit: usb disk not usb drive
When you connect a cable from your pc to the tablet the pop up is to allow the tab to unmount the internal sdcard so your pc can read it.

I do not understand...what is location of the usb files then ?
Open iFileManager and hit the icon that looks like a house. Scroll down and you will find a folder named usbdisk. That is your usb drive. Open the folder. I'm assuming the usb drive is plugged in

/usbdrive is empty.
It becomes populates when i insert a mini usb cable and connect it to the pc.
This give me the mount option and only then i see files under /usbdrive.
idk then, I never had a problem reading the usb drive on vegan beta4. Sorry I can't help
OK, found it.
I have to unmount the sdcard first. Then the usb drive shows with files.
Thanks.
Cool....You may wanna drop a note in the vegan thread on what you did. Maybe others have had the same issue.

Hey. I just got a USB Flash Drive and tried connecting it to my GTab but no dice. I am running Vegan 5.1 and using ES File Explore. I navigate to the root directory and see sdcard, sdcard2, and usbdisk. Sdcard and sdcard2 has my internal storage and my micro usb storage files respectively. But nothing pops us in usbdisk. I tried removing the microsd, rebooting with the USB inserted, and unmounting the microSD but no dice.
Any hints?
Thanks,
Scott
Update: So I tried going to settings and unmounting the sdcard and now I can see the USBdisk. Odd. If I want to transfer data from one drive to another, I cant accomplish that because the SDcard is unmounted. Also all my appdata and stuff are not present. Any way to have both of these drives mounted at the same time?
Thanks
Hi to all!
Here's the problem that I have.
After upgrading my Xoom (US 3G) to Tiamat 2.1 Hammerhead USBOTG stopped to work. When I try to connect flashdrive via this cable it blinks only once and that's all. The folder USBOtg is empty -> nothing is shown (but I know that there are files). I tried to format flashdrive to various filesystems (NTFS, FAT32) -> no result.
Another strange thing after upgrade is with MicroSD folder. It shows me only old data. All new one that I copied to it via PC it doesn't show at all. AND!!! PC doesn't see the content of folder with name "external" on Xoom but when I copy there files from PC then Xoom can see them.
May anyone advice any steps to return usbotg and microsd in normal working state?
I tried to re-flash Xoom with previous various versions of firmwares (mods) -> the same situation.

Two different issues--if you read the release notes with the Hammerhead Rom, Team Tiamat removed the USB Mass Storage enabling that had been in earlier Rom, due to various difficulties. So that means you can no longer use your PC to copy files into the micro sd card in the Xoom, but you can cop files directly to the sdcard using an adapter or card reader. Your Xoom should still have access to the files on your micro sd card at mnt/external1.
The usbOTG works fine for me but it needs the help of an app like USB Mass Storage Watcher OTG or Drive Mount. Both will work. It also helps to reboot with the drive plugged in the first time if you are having a hard time getting the Xoom to recognize it.
Thanx! Drive Mount helped me with recognizing and mounting flash drive (but only after Xoom reboot with drive plugged in). USB Storage Watcher OTG crashes everytime when I start it with drive connected -> with disconnected it starts normally but won't see any after-connected drives. Ssems that I'll use Drive Mount program
As for MicroSD -> even connected directly to PC and copied some files to it Xoom still sees only old data. Any ideas?

Actually, try checking the folder mnt/external1 (1) as this is HC3.2's official mount point. The Microsd mount point is an artifact of an older Rom.
i am using hammerhead rom with tachi kernel.
yup the usb otg not working.
tried both usb watcher and drive mount.

Make sure that you are using a REAL usbOTG cable.
A real USB otg cable? What needs to be special about the cable in order for it to work?

This is where I will suggest that you do some research. Start with this forum and then search elsewhere. Just today I have answered this question 3 times. Search on my name and you will see my posts with your answer.
i am using micro usb male to normal usb female.

but others have also mentioned that usbotg not working after they updated to 3.2

Your cable will never work because it is not OTG. OTG has a different pin configuration to allow the Xoom to function in usb host mode. If you are handy with a soldering iron you could make one, but why not buy one, they are availble. Here is my Google search for USBOTG Xoom to get you started: http://www.google.com/search?hl=en&source=hp&q=usb+otg+xoom&aq=2s&aqi=g1g-s9&aql=&oq=usbOTG
Hey guys, just got a Unitek Micro SD Card Reader (SN:131000001778) with a 32gb micro sd card. I hooked it up using Stickmount, I can access the memory card, but when I go to unmount it, nothing happens and when I pull the reader, I get "USB storage unexpectedly removed". I uninstalled Stickmount and loaded USB OTG Helper, when I hook up the reader and hit mount I get-
"Mount started at: /storage/UsbOtgDrives"
"No drives mounted! (code 9)"
When pressing unmount, I get-
"No drives found to unmount!' Of course.
Is there any way to get it to mount or unmount, and am I possibly looking at data corruption if I'm unable to get the drive to mount or unmount when inserting or unplugging it?
Solved: Kinda
Guess I have to use Settings/Storage to mount and unmount usb storage. Still doesn't explain why Stickmount and USB OTG Helper do not work. Is it an Android 4.x limitation?
Stickmount works just fine with my Meenova... not sure why it wouldn't work unless that OTG is not compatible...

Not sure why, I just got done using it and unmount through settings works perfectly. I just uninstalled USB Otg Helper and it still unmounts fine. I'm not gonna worry about it unless my data starts getting corrupted which it shouldn't now or I use a rom or kernel that doesn't have USB Otg built in which would be a rarity now a days.
HI guys, I am very satisfied with this phone when I got it a week ago. However, I was facing sometimes my phone unable to mount USB OTG storage, I mean the USB drive won't lit at all / detect by phone, I have to reboot the phone then it only gets detected. Any other way round to solve this without rebooting?
I haven't had trouble using my OTG usb stick so far. Have you tried using Nexus Media Importer? It lets you mount/unmount on demand.
Does it show the USB drive as unmounted in the Storage menu?
Also, did you try a different thumb drive with a different filesystem on it? I cannot reproduce your issue at all.
Ok after my investigation, the USB OTG still works but just the USB port of my phone unable to supply power, if I use a power bank + USB hub then connect to my phone, my phone detects the USB drive. Similar to somewhat my phone requires external power to mount. But if I reboot my phone then the USB OTG work properly again though. Until I remove and remount it next time, then the problem occur again.
Currently my phone setup as my signature. No custom kernel but just recovery.

Ok I know whats the problem now. You can try during deep sleep insert in your USB OTG. It can't detect at all even if you remove and reinsert. Have to reboot the phone. So my guess is right I think. The phone have to screen on to insert USB OTG or else it cannot detect.

I don't have 1TB but I have 500GB and it works without external power.

few older phones supported 500gig portable hard drive too but did not support 1tb, my phone will be delivered tomorrow I'll update here then.
Fingers crossed.
I just tried a 16GB USB drive through an OTG cable, and it didn't detect it. My screen was on, and I was running stickmount as well.
I had to restart the phone to get it to detect.
I have the same issue with my N8010. Have to restart to get it to recognise the USB.
Hopefully, there will be a simple solution to this.

Awesome, so my 1TB is working with the one no problems whatsoever.:thumbup:

Well it seems in my case it's rather random, sometimes USB drives (or HDD's) will mount, other times nothing happens at all, while some drives refuse to mount at all.
Maybe it's faulty cable don't know?
I have problem
I was able to mount USB 3.0 64 gb without any formating, and it shows in settings too, but now I can't see it in settings and in El file explorer it is very slow.. What should I do, I can't format to fat32
Same Problem
I can not get any drive to stay mounted, cable works fine on nexus 5 so do the drives but no luck with opo has anyone any info on this since oct 2014 post
