I recently acquired two Compaq Armada M300 laptops at auction. They both have
the same problem: they won't recognise anything put in the usb port (pendrive,
external cdrom, usb mouse). I notice a setting in the bios for 'legacy usb'
and tried both switching that on and then off, but to no effect. Any
suggestions, apart from 'broken'? TIA

Since USB ports carry voltage, it's possible that the previous users shorted
them out. That may be repairable, but working on laptops is difficult. You
might check to see if there is a voltage on the port. There is a diagram on
this page:
http://www.usbman.com/Guides/Belki [...] sembly.htm

An alternative would be a PC card slot adapter for USB. The disadvantage
there is that the PC slot doesn't provide voltage to the USB device, so many
of them come with a pigtail to the keyboard port or built in USB. If the
built in USB is fried, but still provides voltage, that still okay. But if
there is no voltage, be sure to go for a card that uses the keyboard PS2
port.

Hmmm. I wonder why they were at auction. I think we know. ;-)

What operating systems are they running? HP/Compaq still has drivers for
lots of Windows os's for this machine. Here's a Tinyurled link:

You might try installing drivers, etc. and see if that does it. Another
good way to test if you have a hardware problem or a Windows problem is
to boot with Knoppix, a Linux distro that runs from cd. If the USB
ports are recognized by Knoppix, you'll know that it is a Windows
problem, probably drivers. If Knoppix doesn't see the USB ports either,
then sadly you know the answer is "broken".

Another poster has suggested getting a PC card USB adapter. That's a
good idea, and offers some advantages. Generally the PC card adapters
have two USB sockets. Having only one built-in adapter is frustrating.
Also, you can get a USB2 adapter, which is a lot faster than USB1. It's
true that you can't high-current self-powered devices from one, but I
have no trouble with flash memories (for instance).

I've got an M300, and it's a great little machine. The built-in USB
port works, but I'd say I use a PC card adapter more than the built-in
USB port because of the speed of USB2.

Thanks for the two replies. Both laptops will now recognise most usb devices.
The problem turned out to be caused by my first trying a usb2.0 device
(external cdrom) on what I now believe to be a usb1.1-only enabled laptop. It
wouldn't recognise the cdrom but then somehow fouled the windows (98SE) system
up, refusing then to see any usb1.1 device. After shutting down and booting
windows it then recognised the 1.1 devices! This happened on both the laptops.

Is there no way to get a usb2.0 device that's not backward-compatible to
work on a machine with an older motherboard? I assume a bios update wouldn't
do the trick?

Everythink I've read says that 98SE is marginal when it comes to USB
support. Could this be the problem?

You're just being hopeful, MrB. ;-) Win98 FE was iffy with USB; SE was
OK although of course you needed to supply drivers. I really think your
ports are broken. Try what I suggested with Knoppix - if you're unsure
how to do this or it feels too geeky, get a knowledgeable friend or
local pc shop to test for you. Otherwise, boot with Knoppix and plug in
a USB drive. If Knoppix sees it, then you know for sure the problem is
your operating system (Windows). If Knoppix doesn't see it, then you
know its hardware.

I had Dell notebook with USB1 port and Windows 98SE. USB2 devices often
would not work with it at all. The same machine with Windows XP will
happily take USB2 devices in its USB port (though only working at USB1
speed of course).

My Compaq Armada M300 has Windows XP. Plugging USB2 devices into its
USB port (USB1) doesn't upset it.
