ACPI kills USB mouse

[Robert William Vesterman]

Hi,

I've been having a hard time getting my USB mouse to work.  Tonight, I 
accidentally booted without ACPI support, and the USB mouse magically 
worked.  I tried booting with and without ACPI support several times 
thereafter, and each time, the USB mouse worked if and only if I hadn't 
booted with ACPI support.

Is this a known problem? Is there a workaround? Is there any sort of 
information I can gather that might help to narrow down the problem?

This is with 5.3-RELEASE, by the way.

Thanks in advance for any help.

Bob Vesterman.
