How much data transfer can USB connections handle? Would they be a bottleneck for a broadband connection?

Depends on how broad the band is. If you are talking about a typical consumer broadband account, most definitely not. If you are talking about an OC3, well....:D.

You should have posted this on the lounge section I believe. goodness0001 06-20-2002, 10:52 AM Just a cable modem connection, i have never used it before and was just wondering for some other people that use it and complain that it is slow. Jason_Berresford 06-20-2002, 10:54 AM USB (LOW RATE) - 1.5 MBPS USB (HIGH RATE) - 12 MBPS USB 2.0 (INTEL) - 480 MBPS goodness0001 06-20-2002, 10:54 AM sorry about the locaiton, someone can move it if they desire. HostInspect 06-20-2002, 10:54 AM Looking at it closly, if it was possible, I know it isn't. We are talking about an OC3, STS3, OC-3c or maybe can top to an OC-12, STS12 speeds!
