USB modems will consume CPU cycles to perform their work. They consume some CPU cycles even when not online; since they attempt to remain synchronised with the exchange whenever it is plugged into the PC. On a P200 using 512kbps download the CPU load is around 30%. On a Pentium-III class system with an Intel USB controller such as the 82801BA/BAM, CPU load will be less than 1% - this varies according to the chipset used on the motherboard though.
