I
sc (PS2)
2.1 A Maximum output current of the host PS2 port.
C
a (USB)
20 µF This value is the maximum total capacitance that can be
connected to each USB port when used singly or together.
The total capacitance of each USB peripheral and its cable
must not exceed the indicated value.
C
a (PS2)
20 µF This value is the maximum total capacitance that can be
connected to a single PS2 port when used alone, or the sum
of the total capacitance connected to both PS2 ports when
used simultaneously. If multiple PS2 peripheral devices are
used, the total capacitance of all devices and their cables
must not exceed the indicated value.
L

L
a (PS2)
3.11 µH This value is the maximum total inductance that can be
connected to each USB and PS2 port. The total inductance
of each peripheral device and its cable must not exceed the
the indicated value.
