Hi,
I've recently started working on ixp465, with 2.4.20 linux from Monta
vista. Currently I'm trying to test USB host port on ixp465 board and
I'm running into problems.
Please excuse me if I sound too dumb, as I don't have lot of working
experience with Linux and USB is totally new for me.
I want to test USB host port, by attaching some flash/pen drive. My
questions are:
1. How do I know that kernel is recognizing USB port? lspci and
/proc/pci output does not show any USB entry. All it shows, an entry
for intel's processor and another for ethernet. I don't see any USB
entry in /proc/interrupts.
cat /proc/pci shows:
PCI devices found:
Bus 0, device 0, function 0:
Co-processor: PCI device 8086:8501 (Intel Corp.) (rev 0).
Prefetchable 32 bit memory at 0x0 [0xffffff].
Prefetchable 32 bit memory at 0x1000000 [0x1ffffff].
Prefetchable 32 bit memory at 0x2000000 [0x2ffffff].
Prefetchable 32 bit memory at 0x3000000 [0x3ffffff].
Prefetchable 32 bit memory at 0xff000000 [0xffffffff].
I/O at 0xffffff00 [0xffffffff].
Bus 0, device 1, function 0:
Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 8).
IRQ 28.
Master Capable. Latency=128. Min Gnt=8.Max Lat=56.
Non-prefetchable 32 bit memory at 0x4bfff000 [0x4bffffff].
I/O at 0xffffffc0 [0xffffffff].
Non-prefetchable 32 bit memory at 0x4be00000 [0x4befffff].
2. I configured kernel, using make menuconfig for :
a) USB support b) Different host controllers as modules. I tried with
EHCI, UHCI, OHCI and nonPCI-OHCI. However, anytime I try to load these
module I don't see any message on console/dmesg. The only time I see
some output on console is when i use uhci.o and that too, it just
displays the version(Host Controller, v1.1) and then insmod fails
saying "no device found".
3.I configured kernel for USB device filesystem and mounted usbdevfs
on /proc/bus/usb. After mounting, I could see 2 sub directories
devices and drivers. I don't see any other numbered directory such as
00 or 01(which I guess, indicates number of host controllers).
Am I missing something very basic in my understanding on USB working?
I'm assuming the host controller driver(EHCI/UHCI) provided in linux
2.4.20 should be sufficient enough to detect USB host port on board.
Please correct me if my understanding is wrong. Do I need to do any
development to get host functioanlity working for USB on ixp465.
Response appreciated,
Hallu
