This is a placeholder topic for “USB OTG Cable - Female A to Micro A - 4"” comments.
USB On-The-Go is a really useful USB specification! It allows some small devices that would usually be unable to act as a host to have limited hosting capabilities! USB-OTG is common for things like tablet computers and smartphones in order to allow for USB peripherals like flash-drives, keyboards, etc. to be hooked up.Read more
Is this cable for sumsung users ?
This is not specifically designed for Samsung. It should work with Samsung devices though, as long as it has a microUSB port!
If the Micro USB side has the ID (pin 4) tied to ground it will work with a Samsung Phone. Have used a similar cable very successfully. The phone switches to Host mode when the cable is plugged in; allowing access to the data on a SD card or USB stick. The USB stick shows up as another storage device in file manager.
But, it will not work with portable spinning USB hard drives; the current draw by the disk motor is too high.
The above is from personal experience.
