Plugable USB 2.0 MicroSD Card Reader for Phone, Laptop, and Tablet

This allows users to swap a single storage device between a wide array of devices like most popular Android phones and tablets– even those lacking MicroSD slots like– as well as traditional notebook and desktop PC’s. If you need an easy way to move data back and forth from devices with only a MicroUSB connection and your tablet, notebook, or ultrabook with full-size USB type A ports, the USB2-OTGTF should help.

To access the card, simply use Windows Explorer, the Finder in OS X, or your Android file manager of choice.

Q: How do I insert the microSD card?
To use, simply insert a formatted MicroSD card into the upper portion of the full size USB “Type A” port as illustrated here.

Correct Card Placement

Micro SD not insertedCorrect Micro SD placement
Take care to align the SD card so it is in the upper portion of the USB 2.0 full-size “Type A” connector, covering the gold dots in the connector as shown above.

Incorrect Card Placement

Incorrect Micro SD placement
Before fulling inserting the MicroSD card, make sure the gold dots are covered and you can see the card in the small cutouts in the USB 2.0 Type A port.

Be very careful to *NOT* insert the card fully when the gold dots and electrical contacts in the top of the USB 2.0 full-size “Type A” port are still visible. Doing so will prevent the card from working until it is inserted correctly, make the card very difficult to remove, and may even result in damage to the card or device if used when improperly inserted.

Q: Do I have to install drivers?
A: This answer will depend on which device you are using.

For PC’s and Macs, no- the USB2-OTGTF is plug-and-play. Just insert a media card, connect to a USB port on your PC, and go!

For Android devices, please note that not all Android builds include support for the USB Mass storage class. For example, the popular Nexus 5 requires additional applications to enable access. Other devices, like the Samsung Note 2, will automatically mount properly formatted MicroSD cards. If you have trouble accessing the card, check our blog post on options for adding USB Mass Storage support to Android devices.

Q: How do I import pictures from my media cards?
A: This depends on what operating system you run. On most Windows PC’s you can use the “Import photos and videos” feature by simply plugging in the media card reader with a card in it. A similar import manager is available in OS X, as well as most major Linux distributions.

Q: What does the blue LED mean?
A: A solid blue LED indicates the reader is powered and ready to work. The LED will flash during active data transfer.
