Re: [9fans] evoluent mouse review

[Dave Eckhardt <davide+p9@cs.cmu.edu>]

I bought one of these ("Evoluent VerticalMouse 3 Rev 2", aka VM3R2).

It doesn't work with my KVM (IOGear GCS1734, neither top of the line
nor junk), not with Linux or Plan 9:  horizontal tracking is fine, but
vertical tracking goes only up.  It works ok plugged directly into a
Linux box.

After some mail back and forth with Evoluent, the bottom line is they
don't care.  They began with a defensible position (not all mice work
with all KVM switches), but, when asked to name *one* switch the VM3R2
works with, they quit answering mail.

Note that their web site warns against KVM switches when using the
Windows driver (as if!), but does not make a general warning.

It's an interesting device, but when using some (maybe all?) KVM
switches you're better off with an $8 Logitech throwaway.  Too bad.
