Re: [Linux-usb-users] FAQ?: List of know function interface cards.

[Matthew A. R. Sherian]

This is rather perplexing than, as  I have the ohci driver configured to load, and it just will not detect the new cards. It is 1.1 backwards compatible. 


    
    [root@mars root]# lsmod | grep usb
    
    usbcore                77024   0 
    
    [root@mars root]# modprobe usb-uhci
    
    /lib/modules/2.4.18-3smp/kernel/drivers/usb/usb-uhci.o: init_module: No such device
    
    Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
    
    /lib/modules/2.4.18-3smp/kernel/drivers/usb/usb-uhci.o: insmod /lib/modules/2.4.18-3smp/kernel/drivers/usb/usb-uhci.o failed
    
    /lib/modules/2.4.18-3smp/kernel/drivers/usb/usb-uhci.o: insmod usb-uhci failed
    
    [root@mars root]# 
    
    
    
From dmesg:


    
    usb-uhci.c: $Revision: 1.275 $ time 07:32:55 Apr 18 2002
    
    usb-uhci.c: High bandwidth mode enabled
    
    usb-uhci.c: v1.275:USB Universal Host Controller Interface driver
    
    
    
As you can see the drive tries to probe, but doesn't get the correct communication back. (at least that's my interpretation)

Hi Matthew,
	If it is the NEC USB2 card it should also be usable at 1.1 speeds 
using the ohci driver. You need to use that for non-USB2 devices even if 
yuou load the ehci driver (it only handles the USB2 devices). You might 
want to read;

	http://www.linux-usb.org/usb2.html

That lets you know that 2.4.19 will have EHCI support (you can try a 
pre version just now if you want to stick with 2.4).
	All interface cards are suppose to follow the three standards and 
should work (ehci, uhci or ohci).

						regards,

						Stephen.
