USB 2.0 & 1.0 Confusion?
Posted by Radith on August 2nd, 2005


Just wondering:

Would a USB 1.0 device still work @ 12Mbps in a USB 2.0 port.

Thanks in advance.

Yes. USB 2 will slow down accordingly.

Yes it would. But, a USB 2.0 device would NOT work in a USB 1.0 port.

I have a USB 2.0 Flash Drive that works fine in a USB 1.0 port!

I think you can have a USB 1 or 2 device plugged into a USB 1 or 2
controller. You will only get full speed with USB 2 device into USB 2
controller. As soon as one end starts talking at USB 1 speed, then both
devices switch to the slower speed. Everything should be compatible though.

works at the lower speed when plugged into a USB 1.0 port. With XP you get a
message advising you of this.

Same with my Canon EOS 350d. USB2 camera. PC is USB 1 - works fine, but at
USB 1 speed (obviously).
