The Power key on my Mac USB keyboard doesn’t seem to work.

the ServSwitch USB’s rightmost USB-peripherals port (see Section 4.3.2).

I can’t do any of the Mac Power-key functions with my PC USB or PS/2 keyboard.
Unfortunately true. For Power-key functions, you must plug a Mac USB keyboard,
at least temporarily, into the ServSwitch USB’s rightmost USB-peripherals port (see
Section 4.3.2

My video quality is poor (smearing, fuzziness, rippling, etc.).

ServSwitch USB Plus only: My PS/2 mouse doesn’t move the cursor/pointer.
Check the mouse connection to the Switch; if it’s OK, try changing the CPU
channel to recover the mouse (see Section 5.5).

ServSwitch USB Plus only: My PS/2 or PC/AT type keyboard doesn’t function when
it’s attached to the Switch, or functions only intermittently. The Num Lock LED
doesn’t always light when the Num Lock key is pressed.
Some older keyboards were designed for use with specific computers and are not
truly PC/AT or PS/2 compatible. These are not common, but if you’re having
problems like this and you’re using an old keyboard, try a newer keyboard.

ServSwitch USB Plus only: Just using my PS/2 mouse normally causes the Switch to
change the CPU channel unexpectedly.
Some cheaper PS/2 mice are not fully compatible with the ServSwitch USB Plus
and can lose data, which—if mouse switching is enabled (see Sections 3.5 and
5.5
change the CPU channel unexpectedly.
Some cheaper PS/2 mice are not fully compatible with the ServSwitch USB Plus
and can lose data, which—if mouse switching is enabled (see Sections 3.5 and
5.5
)—sometimes causes the Switch to interpret a data stream as a channel-change
request. Try using a Microsoft, Logitech, IBM, Compaq

, or Hewlett-Packard

mouse instead.
