USB 2.0 supports a maximum signaling rate of 480 Mbit/s
USB 3.0 > Firewire > USB 2.0
the answer is USB 2.0 High Speed
Could it be an internal media reader running on USB 3.0, 1394b, and finally USB 2.0
It has basic tape transfer speed which is minute for song, minute for transfer.
you can purchase and install a pci card that has the current generation of usb to allow faster transfer to devices that also support the new version. The newest version is usb 3 and the ports are blue
I think, if your camera is using USB 1.1 while your computer is USB 2.0, it will work just fine, with slower transfer speed. On the other way, it won't work.
USB 3.0 port
Think of it this way... Your USB drive is hi-speed. Your port isn't. So your USB cant use its hi-speed capabilities because the port is not hi-speed. If your question meant, how will this affect you? It won't affect you too much. It will simply just transfer data to and from the USB at a normal speed instead of a hi-speed.
interface rate, USB 1.1 (12 megabits/sec) , USB 2.0 (480 megabits/sec), USB 3.0 (up to 5gbps )
yes,it is possible and there is no effect on the speed of data transfer
All of the USB devices themselves as Hi-speed. USB 3.0, is the recent hi-speed USB.
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
