My experience of USB is that it is slow, and every now and again my Win98
system just stops, and then bursts into life again (Pentium III). This
happens when using the USB for printing.
However, my Win95 system (Pentium P200) now has up to COM10: (2 on
motherboard and 8 on a Brain Boxes Lynx ISA card) and this is incredibly
swift with no "pauses".
