USB 2 vs USB 1?
-
Hey All, My neice just bought a used laptop and a new USB flash drive. When she plugged the flash drive into the laptop she got a message "No high speed host controller installed ...". I am assuming this to be because the laptop has USB 1 ports and the drive is a USB 2 device. Can a USB 2 device work on USB 1 ports? Is it just a matter of updating the drivers? If so where would one get the drivers? I dislike all the hardware stuff X|

You should be able to use it as is. That message is not saying otherwise, but it should be more clear. The flash drive is made for USB 2.0, but it will work with USB 1 as well (as will all USB 2.0 peripherals) - it just will not transfer data at the faster speed that USB 2.0 provides if the port does not support USB 2.0.

Yes, the standards are all backwards compatible. They just negotiate to the speed of the slowest piece of hardware, kinda like Ethernet: if you have a 10Mbit card on one end and a 10Gbit card on the other, they will negotiate the speed to 10Mbit sothey can communicate. The OS (or maybe the driver?) knows that the port is low speed and just feels like rubbing it in your face ;P

it should work, but will use the lowest common speed (just like it used to be for a 9600 and a stellar 28.8 modem for oldies like me :~ ) -- modified at 19:39 Friday 14th July, 2006

As the others are saying it should fall back. The exception to the rule are devices such as DVB-T / ATSC USB tuner sticks which receive off air at a rate faster than USB 1.0 supports. There is just no way to squeeze 24 / 19 MBits/s into 12 MBits/s
