after dealing with PCI usb hub. i went and got external usb hubs and yes it worked on windows 7, but only FULL speed, my cam went from fast to laggie, iphone connect to usb hub had a message " it can perform faster if connect to a high speed port" , i check under device manager and it says " the device is operating on FULL SPEED "
i have check online, full speed = 12 mb/s , high speed = 480 mb/s
are there any ways to change this?
Most hubs can't run high speed anyway. They're connected to another usb hub whose maximum speed is high speed. This means that they can't possible go high sped because there's anywhere from 2-7 devices plugged into one port. Now, if you have a PCI USB Hub then you've got a real high speed hub.
My first question, why did you go to a PCI USB Hub in the first place and did you leave it behind (remove it), like your message suggests?
What is the new hub you bought plugged into, and what is the hub itself rated as? USB 2.0?
Devices have to match USB port speed also to run at that speed.
I too have old stuff with 1.1 ports, including G11 keyboard; for running a keyboard, microphone, or mouse, 1.x is just fine, but for external storage, yes you want 2.0 or even firewire.
I dug a little deeper, and web cams will need a higher speed USB, definitely.
Did you just recently add more USB devices + the hub?
In that case you are using up bandwidth (taking it away from camera) and if it's too much then yes you will start to take a performance hit, and if you are using 1.1 USB instead of 2.0 now, you are definitely taking a step backwards and have to get back to 2.0 or you web cam is doomed to stay a laggy beast.
