Network equipment question(s)
Greetings:
I need information on the new USB 2.0 equipment.
Is it correct for me to assume that if I buy a USB 2.0 card that plugs into a PCI slot, it will operate at the full potential of.... 60MBs?
If I buy a 4-port USB 2.0 PCI card and plug 3 USB 1.0 devices into it and plug 1 USB 2.0 device into it, will the USB 2.0 device operate at it's full potential? In other words, will the USB 1.0 devices affect the speed of the whole card?

The USB 2.0 standard is 480mbits. The USB hub if it is a true USB 2.0 rated HUB will autodetect the USB type of the device you connect to it and will assign the correct bandwidth. So, yes your 2.0 device will receive the higher bandwidth (however, there are many factors affecting the overall process like your software stacks, cpu load, bus load, etc.., so you will more likely get rates closer to -3 ports at 1.1 (12mbits for 36 total minus mbits, leaving somewhere in the neighborhood of 444mbits -NOTE: in real world it will be less because of all the foregoing factors) while your 1.0 and 1.1 devices will get their full allocation. Check USB.org for more info.
