Package: hotplug
Version: 0.0.20040329-25
Severity: normal
When I plug in my mobile (Sony Ericsson K750i) the corect drivers
(cdc-acm and usb-storage) are not loaded. If I turn on the debugging
I get stuff like this in syslog:
Sep 11 20:25:50 lastan2 default.hotplug[9721]: arguments (usb) env
(OLDPWD=/ DEVPATH=/devices/pci0000:00/0000:00:10.1/usb2/2-1/2-1:1.2
PATH=/bin:/sbin:/usr/sbin:/usr/bin ACTION=add PWD=/etc/hotplug HOME=/ SHLVL=2
DEVICE=/proc/bus/usb/002/004 PRODUCT=fce/d016/0 TYPE=2/0/0 DEBUG=yes SEQNUM=414
_=/usr/bin/env)
cdc-acm should be descovered by the interface class/subclass/protocol as
defined in /lib/modules/2.6.8-11-amd64-k8/modules.usbmap:
cdc-acm 0x0380 0x0000 0x0000 0x0000 0x0000 0x00
0x00 0x00 0x02 0x02 0x01 0x0
The problem seems to be in the /etc/hotplug/usb.agent. Since INTERFACE
is not defined in the environment, usb_convert_vars() tries to get this
info from sysfs. [ -r $SYSFS/$DEVPATH/bInterfaceClass ] fails because
sysfs does not have the new info yet and the interface parameters get
set to default values (1000).
If I add a 'sleep 1' before the call to usb_convert_vars() sysfs is
refreshed with the device info and the drivers get loaded.
