You can use USB for everything! I have these speakers but I lost the adapter. I read some things about USB powering and I started to make an USB adapter for my speakers and it worked!
Step 1: Materials
- Speakers with a plug showed on the picture
- A pair of scissors, a knife or anything to strip the wire (even your naisl will work)
- Usb wire, doesn't matter what kind but it must have a male plug.
- Connecting brock.
