Portable USB 3.0 drive powered with USB 1.1

post #1 of 4
Thread Starter 
Would a portable USB 3.0 drive work on a USB 1.1 port?

I know the data bus is backwards compatible, but the portable drive only gets its power from the usb port. I'm not sure if USB 1.1 would be able to deliver enough power.

This is the drive I'm talking about.

Hello

USB 1.1 and USB2.0 max load of 500mA

and for USB3.0 max load of 900mA.

So i think its smartest to send an email to the manufacturer of the external hdd.

I would be surprised if it worked. My USB3 flashdrive doesn't work on USB 1.1 ports. Little known fact - although USB's spec mandates full backwards compatibility, it does it by having a USB 1.1, USB2, and USB3 controller for each USB3 port. rolleyes.gif Many new USB3 devices (like my flashdrive) skimp and only have a USB2 and USB3 controller within. When I plug it into a USB1 port, nothing happens, indicating a complete lack of communication.
