Is there a Usb 3.0 to Usb 2.0 adapter?

[exomegan]

The usb 3.0 port in my laptop is broken and i only have a usb 2.0 port alive and my external hard drive can only be read in usb 3.0. Is there a usb adapter that can convert usb 3.0 to usb 2.0?

I have found one online but What worries me is the will it work?

I thought all usb 3 device/readers were backwards compatible?

You shouldn't need an adapter as the ports are supposed to be backward compatible. Your USB 3 device will simply run at USB 2 speeds when using the older port. If however your device requires higher power draw than a USB 2 port can supply, an adapter won't help.

Someone if trying to rip you off, you don't need USB 3.0 to USB 2.0. They are all backwards compatible down to USB 1.1 . The issue is if the USB device needs more power than what a USB 2.0 port can provide, than it won't work. USB 3.0 can provide 500mv where as USB 2.0 only supplies 250mv max. Some little external hard drives that run off 1 USB 3.0 port needs 2x USB 2.0 ports to run otherwise not enough power (or external power adapter).
