Why then, have there been fewer and fewer PC card peripherals in recent
years, superseded by USB (1.1) peripherals?

CardBus is not PC Card. PC Card is very slow like ISA bus. CardBus is

IIRC, PCMCIA maxes out at around 4-5 megabytes/second, a little faster
than ISA.

Cardbus is a similar connector, that's somewhat a cut-down PCI bus, I think
the maximum for large bursts is 32 bits * 33Mhz, or about 233 megabytes/
second, the same as PCI.

fast like PCI bus, around 1 gigabit/second. They use the same pins and
look similar. CardBus cards won't fit in a PC Card socket but PC Cards
will fit in a CardBus socket since the newer bridge actually has two
separate bridges, one PC Card to ISA and one CardBus to PCI -- it uses
the appropriate one.
