I think I have found an error in the usbnet.c included in Linux 2.4.22.
My Zaurus won't connect unless I modify this file.
drivers/usb/usbnet.c has USB_DEVICE_ID_MATCH_INT_INFO set for Zaurus
devices:
{
.match_flags = USB_DEVICE_ID_MATCH_INT_INFO
| USB_DEVICE_ID_MATCH_DEVICE,
.idVendor = 0x04DD,
.idProduct = 0x8004,
.bInterfaceClass = 0x0a,
.bInterfaceSubClass = 0x00,
.bInterfaceProtocol = 0x00,
.driver_info = (unsigned long) &zaurus_sl5x00_info,
}
...
I use hotplug, and the modules.usbmap derived from the above entry.
On my system, /sbin/hotplug is not called with an INTERFACE= argument.
/sbin/hotplug: arguments (usb) env (PWD=/etc/hotplug DEVICE=/proc/bus/usb/002/002
ACTION=add DEBUG=yes OLDPWD=/ DEVFS=/proc/bus/usb TYPE=2/0/0 SHLVL=1 HOME=/
PATH=/bin:/sbin:/usr/sbin:/usr/bin PRODUCT=4dd/8004/0 _=/usr/bin/env)
Thus this never matches.
It appears from the code in usb.c that there will only be an INTERFACE=
argument if the class is 0, which it isn't.
This module (usbnet) seems to be the only one in the usb group that
sets this flag. The macros in linux/usb.h only set one flag or another,
not two.
After the following change, it works well.
Is this an error in usbnet.c, or do I have something else that is old or
mis-configured?
