Hi Harvey,
Thanks a lot for your report, and sorry you're having problems.

Bonjour,
I have a very old Hewlett-Packard PC with Ubuntu 12.04. Recently my built-in usb ports have become very flaky so I have bought a new low profile PCI 4-port USB 2.0 hub (VIA Technologies, Inc.) which has failed to install.
This is a plug-in PCI card, right?
Quoted 21 lines
Immediately apparent is the !!!error notice. I have spent several hours in research with no success - I am obviously not doing it right!
Odd, too, that lspci and lshw only enumerate 3 ports on this card, whereas there are 4.
Any help gratefully received. Failing direct help, I should appreciate some pointers on how to start self-helping ... Ta! For example, I imagine it would be useful to understand the error message!
I shall be glad to supply any further diagnostics - just tell me! I am not a stranger to programming, but my major interests have been DBs rather than hardware...

lsusb does not find these ports
dmesg has no references to this card, that I can discover/recognise.lspci -vvv -s 01:01

This particular device looks like a bridge, not a USB controller. Can you collect the complete "lspci -vvvxxx" output (as root) and the complete dmesg log?
The first step is to figure out whether the PCI core is enumerating the device. If nothing else works, you could collect the dmesg log with the card removed, then again with the card installed, and diff the two. The PCI core prints at least one line for each PCI device it finds.

With the card installed, your dmesg log shows the following new devices:
pci 0000:01:01.0: [1106:3038] type 0 class 0x000c03 pci 0000:01:01.1: [1106:3038] type 0 class 0x000c03 pci 0000:01:01.2: [1106:3104] type 0 class 0x000c03
But I think there's a hardware problem with your card or the bus it's plugged into. Look at the hex data:

^ ^ ^ ^Bit 0x02 of every byte with low-order address bits of 0x2 is set. I think that wire on the bus is stuck.
Can you try a different copy of the same board? Clean out the socket? I'm guessing you don't have another copy of the motherboard to try. But this sure looks like a hardware problem, not a software one.
