Kernel n00b

Hi, I've posted a couple of times on here so far and people ahve been super helpful, so hopefully you'll be able to help me with this lil problem:

I'm setting up my Speedtouch 330 USB modem by following a set of instructions, but have come unstuck on a section to do with configuring the kernel, which I don't know how to do. Here it is in full:


USB support
Your kernel obviously has to support USB to run Alcatel Speedtouch.

Depending on your USB controller (chipset on motherboard/pci card), you'll have to choose between two modules: UHCI or OHCI
Without explaining the whole thing, these are two USB incompatible standards.
This is why you have to know which chipset is yours.

To determine which to use :
# lspci -v | grep USB

You should obtain something like :

usb-ohci : CMD technologies Inc|USB0670B
usb-uhci : USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) (prog-if 00 [UHCI])

If your chipset uses OHCI standard, you'll have to pick usb-ohci (surprising !).
If, on the contrary, it uses UHCI standard you'll have to choose between usb-uhci or uhci. They should work both, but in case you have problems setting usb support with a module, pick the other one, and pray !
Options to allow usb support :

<M>/<*> Support for USB (CONFIG_USB)
<*> Preliminary USB device filesystem (CONFIG_USB_DEVICEFS)
<M> UHCI (Intel PIIX4, VIA, ...) support (CONFIG_USB_UHCI)
<M> UHCI Alternate Driver (JE) support (CONFIG_USB_UHCI_ALT)
<M> OHCI (Compaq, iMacs, OPTi, SiS, ALi, ...) support (CONFIG_USB_OHCI)


When I do the # lspci -v | grep USB thing, I get;

00:04.2 USB Controller: VIA Technologies, Inc. USB (rev 16) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
00:04.3 USB Controller: VIA Technologies, Inc. USB (rev 16) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller

Thanks alot in advance, any help will be greatly appreciated.

Try first lspci -v (verbose) in order to get more details.
According to your post it seems you have a VIA Tech. controller that usually is supported by the UHCI driver.
This link has been very explanatory to me some time ago, i hope to you as well.
