Computer newbies forum: USB 2.0/1.1

Are you asking: what is the difference between 12 Mbps (mega (millions) of bits per second) and 480 Mbps?

If so, then about 468 Mbps, or 40x.

Of course, the real world hasn't seen results near those theoretical limits yet.

As for the actual pin out, the pins are the same.

Except that with my Sony Vaio 2001 model year computer, an add-on pci with five usb 2.0 ports continually crashed my system, and created horrible digital artifacts with my usb audio. I recommend that if you are using usb audio stay with your "built-in" usb ports even if they're 1.1 because there can be major conflicts with the motherboard and bios, which you experience pops and clicks that are very annoying. I also had freezing on images on my webcam.
After three upgrade cards I realized that it wouldn't work with usb audio,or webcams, but did work with the printer, but that isn't worth the problems that occured with my audio. I look forward to my next computer with build in usb 2.0 ports.

My machine specs:

Home built with Shuttle main board with 6 USB-2 ports, AMD 2600+ XP processor, 512 Meg RAM.

Optical drive: Sony 52/32/52 CD burner.

Drive case: BYTECC USB-2.

Procedure: Copy a large file from the USB drive to a folder on my HD. I used the supplied USB-2 cable that came with the case and a several year old USB-1 cable from an older USB Zip-100 drive.

File copied: IE6 full, 48 Meg in size from a CD-RW disk that I had burned a while back.

Results:

USB-1 cable took 25 seconds.

USB-2 cable took 19 seconds.
