12 Mbps for original and 480 Mbps for high speed.

Perhaps a computer processing unit from about 2010.
40 times faster at maximum. 480 MB speed at 2.0.
All of the USB devices themselves as Hi-speed. USB 3.0, is the recent hi-speed USB.
USB cables for original USB can be up to 3 meters (9 feet, 10 inches) and hi speed USB cables can be up to 5 meters (16 feet, 5 inches). (reference p 404 guide to managing & maintaining your PC)

The Generic USB Hub is a HI-SPEED USB device and will function at reduced speed when plugged into a non-HI-SPEED port
A Hi-Speed USB port is 40 times faster than Original USB port running at 12 Mbps because 12 divided by 8 equals 1.5 which is how many Megabytes not Megabits that can be transferred with USB 1.1 since there are 8 bits in one byte.
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.
USB 1.0 has a specified data rate of 1.5 Mbit/s for "low speed" and 12 Mbit/s for "full speed" USB 2.0 has a maximum speed of 480 Mbit/s which has been being called "high speed" however, USB 3 is on the way, (to be called "super speed") and will be capable of transfer speeds up to 5.0Gbps in full duplex. FYI: 8 bits = 1 byte (roughly) 1,024 bytes = 1 Kb (kilobyte) 122Kb = 1 Mbit
Hint hint... high speed
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
USB version 1.1( sometimes called Basic speed USB or Orginal USB) allows for two speesd,1.5 Mbps and 12 Mbps. USB version 2.0 (sometimes called hi-speed USB or USB2) allows for up to 480Mbps.
