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.

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

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

You will probably need an app like USB MassStorage Watcher or Drive Mount (both free) to mount/unmount the drive. It will show up on the same directory level as sdcard (internal storage) and external1. It will be at usbOTG.

i m in same boat. I have XOOM wifi USA version. It is NOT ROOTED.
does it work to read USB drive without rooting?
current OS version on my XOOM is 3.2.1 (HTK75D)
No, you must be rooted and running a custom kernel or Rom that support usb host mode.

Thanks for reply. I m totally new to rooting etc.
well is android 4.0 is going to release for this XOOM model soon? and does it resolve this issue?
I'm betting that our developers are making us an ICS Rom with usb host mode support...
will this also work with a usb gender like http://www.amazon.com/USB-Gender-Changer-Female/dp/B000BSN4UY/ref=pd_sim_e_2 in stead of a usb otg?
I have installed android 4.0 on my motorola xoom wifi usa version.
it is NOT ROOTED.
Can i read usb drive ( pen drive or external hard disk ) with this Or still rooting is needed?
I have following adapter.
http://www.amazon.com/Micro-USB-Mal...3?s=electronics&ie=UTF8&qid=1327371621&sr=1-3
is only rooted is Ok or it need to install other custom OS version?
it will be great somebody can reply ASAP.
So there is no other app that doesn't require root? I just want to hold on rooting the device..is USB OTG supported with 4.0?
I haven't been able to get my external hard drive (Samsung S2 750GB NTFS formatted) to mount since upgrading to Team EOS Wifi ICS ROM. I normally use USB Mass Storage Watcher app to mount the drive but although this is recognizing that I have the drive connected and it allows me to click mount it doesn't mount the drive and the option doesn't seem to acknowledge that's its mounted by changing to unmount. TBH I'm not even sure if the drive is already mounted as its location could have been moved in ICS, like the micro SD cards was. I've also tried selecting the USB mount option in Storage settings but this doesn't seem to work either, though it does cause the drive light to flash off and on when its selected. Also I've noticed in USB Mass storage watcher the drive location is listed as dev/block/sda but I've tried checking here and mint/usbotg with root explorer but have had no luck. BTW I'm on build 45 ATM.
Any help appreciated.

This works for me too, on my ICS rooted Xoom. None of the others I could find, including 'mass storage watcher' did.
I managed to sort the problem by using USB Mass Storage Watcher to create a new folder for my drive, after that I could access it fine. Weirdly the drive would not show up before that and I am 100% certain I was checking the correct location.
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.

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.

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?

Hi,
I am extremely sorry if this is not the right place to ask this.
I got my Mi4i on the first flash. As soon as I got the phone, I did the MIUI 6.5.3.0 (LXIMICD) update. I did not check the USB OTG before the update, so not sure if it worked before the update or not. When I tried USB OTG, the Mount USB storage option is greyed out - always. I tried 2 different USBs and 2 different cables - still no luck. I am starting to suspect if its something wrong with this ROM release, as lots of areas in the setting is greyed out for me (for example, in the Headphones and Audio effects settings, the equalizer settings are always greyed out). So, have any of you tried USB OTG on MIUI 6.5.3.0? Any insights?
Yes I can assure u that USB OTG is working fine on MIUI 6.5.3.0
Check if the USB is a fat32 or ntfs?
Ntfs file system doesn't work with mi4i
Format the pen drive in fat32 and try again
I also tired a sd card reader it works brilliantly
Audio settings will be greyed out until u plugin headphones. Try any earphones or headphones then check if it still is greyed out

Thank you for the reply but I am still facing the issue...
Yes, the file system is Fat32 and the mi4i is still not recognizing the USB. Since the USB OTG is working fine for you, I suspect my OTG cable might be damaged ( weird- I tried 2 different cables).. Maybe I should try a different OTG pen drive?
PS: You were right about the audio settings, those worked when I plugged in the headphone..

If you're USB or SD Card is of huge capacity it may take time to load so I would suggest you to wait for a while, Android checks if the storage has an errors. It doesnt show in MIUI though. But wait for a while after plugging in.

Aren't there root apps which enable ntfs support by installing a ntfs-3g driver?
The functionality is kernel-baked and not all kernels support the ntfs-3g driver. Also Xiaomi seems reluctant to release its sources anytime soon. There are alternatives like Stickmount however.
