answer those questions.

<SimpleSect><Title>How do I report a bug?
In addition to the information required in
/usr/src/linux/REPORTING-BUGS, it also helps
enormously if you provide the output of
/proc/bus/usb/devices. If you are having problems
with your host controller being recognised, it helps to have the
output of lspci -v. If it is supposed to be UHCI, it
helps to know whether interrupts are being generated every second.
What is a good book on USB
I have only read one, and thought it was very poor. I suggest that you
get the specifications from http://www.usb.org
, which are at no cost, are quite readable, and are up to date.
How do I make USB work on my Sony Vaio laptop?</>
<Para>
You may need to turn off the BIOS option for Plug-n-Play operating
system support on some models of Vaio. Then USB should work fine,
although you may have problems with using the modem. This is only
needed on some models.

<SimpleSect><Title>How do I make USB be detected on my machine?</>
<Para>
If you are sure that you actually have a suitable hardware setup,
look for a BIOS option that could be applicable. It might be labelled
as USB, or it might be more obscure, discussing Plug-n-Play, or
having options for various types of operating systems. You may need
to try various combinations.</>

<SimpleSect><Title>I've upgraded and USB doesn't work on my machine anymore</>
<Para>
If you have a motherboard with BIOS set to MPS 1.4, try MPS 1.1.

<SimpleSect><Title>My Asus motherboard doesn't work, or works with only one device</>
<Para>
Some early Asus P2B-DS and P2B-D motherboards have a design flaw that means that
the chipset doesn't get sufficient voltage. I suggest returning the motherboard.
Alternatively, check the Asus website at
