Hi

I am running mandrake linux 9.1. my pc has 2 usb ports on the back which work fine and 2 usb ports on the front which aren't displayed with the usb info program in linux. Can you tell me if there are drivers or some way to get them to work please?

Thanks In Advance

I would try to use them actually.

I have 6 total usb ports and lspci lists:
only 3 hubs, and an EHCI controller.

But all my ports work fine.

try plugging something in and using it.

each hub = 2 ports, normal motherboard.

What USB info program are you using? lsusb ?

If that doesn't work you might check the cable from the motherboard to the front ports got installed by whoever assembled the PC!

I know there is some USB stuff in the BIOS on this PC, but I don't remember if it can be used to change the number of active ports.

i plugged my modem into the front ports and linux didnt seem to pick it up but i will try something else aswell just incase. i know the cable inside the computer is ok because the ports work in windows. i asked in a computer shop and they told me that there should be drivers for the front ports.

I was trying to mount a USB 128MB SAN DISK stick on my front USB ports a little while back.

After a few attempts I remembered that I had not connected the front USB ports, simply because the motherboard didn't have any additional USB headers to connect them to.

my front hub definately works because i can use it with windows. I connected a a device to the back hub and it appeared on the list for the first hub in USB Devices - KDE Control Module (start > Configuration > KDE > Information > USB Devices) so then i conected the same device to the front hub and reloaded the program (so that it would refesh) and it didn't appear in the list for the second hub.

I'm not sure why you would need extra drivers for them since I have a case with front USB ports and they work without drivers. Maybe you should try compiling a new kernel with support for all of the USB hub types.

Type 'lspci' in a terminal as root (or /sbin/lspci as any other user) to see if your hubs are shown. Since you have 4 ports, you should have two hubs that show up.

00:02.0 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)
00:02.1 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)
00:02.2 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)

I have six, and there's the output for the three main hubs using lspci. Remember, PCI is the entire system bus that runs things through the processor, not just the slots/cards that go into them.

Actually. PCI is Peripheral Connections interface, gennerally 32 bit arch, and the only x86 computers that are solely pci are laptops.

But lspci, lists USB onboard hubs and ports cause its connected to the PCI bus.

lspci, isadump, lsusb, etc etc.
