Hi Claudio, Well, I don't think there exist a open driver for ixp465 usb HOST controller yet.
There is for the usb DEVICE controller. The IAL from Intel has some support for usb DEVICE controller but I believe the linux kernel has it's own pure code for this, not depending on IAL. The pen drive you insert is most likely a usb DEVICE, so it want to talk to a usb HOST (like your linux desktop or ixp465 usb HOST interface). Your option is either buy a dist/kernel that has a usb HOST driver for ixp465 (like Montavista) or do your own. Basically you go into drivers/usb/host and copy the ehci_pci driver to like ehci_ixp4xx, change it a lot and debug for a while. (the usb controller inside ixp465 is NOT easy to work with.... :-) ) Good luck. /Per Claudio Scordino wrote: > Hi all, > > I encountered some problems with the USB host support during the porting > of Linux 2.6.17.11 to a Intel IXDP465 architecture (IXP465 processor). > > I ported and loaded the Intel Access Library (ixp400 and ixp400_eth > modules) and loaded the Microcode (cat IxpIxNpeMicrocode.dat > >> /dev/ixNpe). >> > > Then, I loaded the following drivers, as proposed by Maulik Mankad on this > mailing list few months ago: > > usbcore > scsi_mod > sd_mod > usb-storage > ehci-hcd > > Just to be sure, I also loaded the following modules: > > sg > ch > libusual > > However, when I insert a USB host (ia pen drive) the system does not see > it: I cannot see the device using dmesg, /proc/scsi or /sys/class/usb. > > Since the Montavista kernel is not freely downloadable, I cannot either see > how they solved this problem... > > Any help and suggestion is very welcome. > > Many thanks in advance, > > Claudio > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
