[Q] USBOTG doesn't work

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

[Q] htc touch2 not detected by usb port

my htc touch2 is not being detected by my PC when connected to the usb port. The phone is getting charged but not being detected. I am out of warranty. Do I have any options other than replacing the usb port of my phone which I feel is not worth it? Can I connect my phone to the pc to transfer files via wifi? Is there a way to flash the ROM?
Thanks

I had the same problem
You need to disable "fast data synchronization" in settings-connections-USBtoPC

Remove PIN as security option and check
Also re-install the drivers properly
Also check whether it's working fine on other PC or not using different usb cable

Is the file size larger 4GB ? Either you sdcard is formatted with Fat32 filesystem with a maximum file size of 4GB per file OR the format is not compatible with MTP. Have you tried connecting the micro sd card to your computer via adapter or cardreader?

This time Yes.. But the error came out even on smaller files exceeding approx.100 MB..
It appears every 2 seconds during the copying process..

You'll have to connect it in another way. Either mount as mass storage instead of MTP OR use a card reader for the micro sd card OR convert the video files to a compatible format.

There is no 'Mass Storage mode'.. But converting video files looks like appealing.. Let me try out that..

O stock rom there is no "mass storage" mode. BUT why don't you connect the micro sd card directly to your computer??

Who does that??
I mean first
1. Open your Phone Cover. (Reduce Life of Cover)
2. Eject SD Card (Increased Risk of Damaging Card)
3. Put it in Card Reader
4. Copy Files with USB 2.0 (No benefit of USB 3.0 support)
5. Put it Back into Phone
6. Close Phone Cover.
and The whole process is time consuming and annoying to me..
Moreover, What you expect from a USD 750 Phone??

Ok i have checked whether it transfers data files other than video files..But no success:crying:. means there in no format related issue at all..

BUT seems to be caused by MTP.

Yes, as i said connect the micro sd card manually instead of using the phone for it.

Its not a fix..its an alternative..

But it's much faster, too. MTP provides lower copying speeds.

Note 3 supports USB 3.0. So MTP is faster than card reader..
Sorry for late reply..

[SOLVED]
I Use Airdroid to transfer files.. and its Fast too..

I can not transfer files to the MICRO SD via USB cable

Could anyone help me?
I can not transfer files from my computer to the Micro SD of LG G Flex 2 through a USB cable. The transfer begins but halfway to appears the message: "device has been disconnected." I have android 5.1.1.

Try a different USB cable or a different USB port on your computer.
