This question seems to have been answered a couple of years ago by Anonymous, but it is of such enormity to me that I need corroboration. I have three computers(2XP,1Vista) with many external HDD's connected to each of them. On boot up, I always get an error message saying "this device would work better if connected to a high speed". Device Manager reports that I have "generic usb ports" and "generic usb hubs". I have been told by people in another forum that to have high speed ports (usb 2.0) I should be seeing the word "enhanced" in these various listings of ports and hubs. This seems incredible to me that all of my computers a stuck with puny usb1.1 ports! In each of these three computers i have installed 2 pci to 4-port usb cards
and they also give me that error message for ext. HDD's plugged into them.
Today I went to a BEST BUY store (noXP or Vista computers of course) and opened up the Device Manager in each of them. All but of one these computers reported "generic usb ports " and "usb root hub". That one computer did have a "enhanced" pci to usb " device, but it also said that it had a usb3.0 port. I talked to one of the"geeks" in their service dept. and he was adamant that a new computer sold in 2011 did not have usb1.1 ports. I'm very confused by all this. Could someone make a comment on this? Thanks for the reply.
Well, just today my pc gave me a similar message after I plugged my camera in!
I just thought it was an anomoly because I never get messages like that.
The first thing that occurs to me is I wonder if your chipset drivers are up to date. You may (and probably do) have USB 2.0, fairly common on even 3-4 year old machines. My system reports several generic USB ports and hubs. I have two "Standard enhanced pci to USB host controller". I also have 5 "Standard OpenHCD USB host controller." My motherboard is 3 years old, AM2+.
Its strange that the OS does not list these under system properties as USB 2.0. But it looks as though everything is working properly on my machine.
