OTG Troubleshooter: Solution of OTG Failing to Recognize USB
"I have been trying to access my USB flash drive on Samsung Galaxy S6 using OTG cable, but it seems that OTG cannot detect the flash drive. I’m sure my OTG cable is working because it works well when testing with a mouse. How can I solve the OTG is not working problem?"
Previously, we have discussed how to watch movies on USB disk by connecting Android phone and USB pendrive with OTG cable. In the process, some complain that the computer doesn't pop anything after connecting OTG USB or the system does not detect OTG USB signal. In this post, let’s see how to fix OTG cannot detect USB.
- Backup your USB drivers first.
- Then, follow the steps below to check whether the format of your USB drive file system is supported by your phone.
STEP 1. Connect your external hard drive to your computer with the USB cable.
STEP 2. Click "Start" and then click "My Computer". In the "My Computer" window, right-click on the drive icon in which the USB device appears.
STEP 3. From the menu, click "Properties". Look next to "File system"; Windows will indicate whether the drive is NTFS, FAT32 or exFAT.
STEP 4. If the file system is NTFS or exFAT, you should format your USB storage device to FAT32 to make it recognizable for OTG. Follow the instructions below to format your USB drive to FAT32.
If the file system is FAT32 but the OTG still cannot detect it, try another USB drive to see if it works. If other USB drive works normally, maybe your original flash drive is corrupted or damaged. Just change it.
STEP 1. Connect USB device to the computer and then click "My computer."
STEP 2. In the "My Computer" window, right-click on the drive icon in which the USB device appears. From the menu, click "Format...."
STEP 3. In the "FORMAT device name (drive letter)" window, under "File system," click the drop-down arrow and select FAT32 and then click the Start button.
STEP 4. At the "WARNING..." message, click "OK" to continue.
IMPORTANT: Formatting the USB storage device will delete all content on the device. So you must backup it first.
STEP 5. At the "Format Complete" message, click "OK".
When you have reformatted your USB drive to FAT32, try again to connect it with OTG. Probably you'll succeed. If you encounter any problems during the process, do let us know.
