Enabling OTG USB and Power Simultaneously on HP Stream 7

USB Y cable

The HP Stream 7 is a great little tablet PC for the money. Unfortunately, there are some limitations. One such restriction is the lack of a full sized USB port. This means that if you want to connect any “real” usb devices, you’ll need to use an USB OTG cable.

But what if you want to power a USB device, like an external hard drive, or an audio interface? Well, you’ll need to do this little trick to power your HP Stream 7 and enable the USB communication between the Stream 7 and the USB device.

Note: It seems worth mentioning that the Stream 7 won’t actually charge in this configuration, but it will power it. Whether there is very little drain to battery or no drain at all, remains to be seen. But at the very least, you will get many hours out of your Stream 7 with minimal to no drop in battery.

You’ll need a USB Y cable like this one and a USB Coupler to do this trick.

Here are the steps to get your HP Stream 7 to be powered by USB and work with an external USB device simultaneously.

Step 1. Insert the Red USB Male A end into the wall adapter for your HP Stream 7 charger.

Step 2. Attach the USB Coupler to the Black USB Male A end of the Y cable.

Step 2. Join the USB Coupler to the device you want the Stream 7 to communicate with.

Step 3. Plug the USB Micro Male B end into the Stream 7.

That’s it! You will notice that the Stream 7 may not charge, but it is actually being powered from the wall outlet and simultaneously communicating with the USB device. This is a great trick for not draining your Stream 7’s battery and still using an external USB device.
