Description Aleksey Nogin 2004-02-24 02:48:32 UTC
When I plug in my USB printer (HP LaserJet 1200), I see the following
on the console:

cat: /sys//class/usb/lp0/bNumConfigurations: No such file or directory
/etc/hotplug/usb.agent: line 144: [: too many arguments

After the printer is inserted, /sys/class/usb/lp0 contains:

# ls -l /sys/class/usb/lp0/

and no "bNumConfigurations" anywhere...

I currently have hotplug-2004_01_05-1 and kernel-2.6.3-1.97

I'm seeing this too, with an HP DeskJet 990cse. On both FC devel and
Mandrake cooker. So, whatever this problem is, it's not specific just
to FC devel...

Comment 2 John Thacker 2004-03-28 16:50:41 UTC
Fixed in upstream CVS on March 14.

See:
http://cvs.sourceforge.net/viewcvs.py/linux-hotplug/admin/etc/hotplug/usb.agent?r1=1.36&r2=1.37

Perhaps this patch should be included if a new version of hotplug
isn't released before FC2?

Comment 3 John Thacker 2004-03-28 16:59:31 UTC
As a further note, this is only representative of a large number of
error and warning messages I see with hotplug and the latest
development kernel (2.6.3-2.1.253.2.1).  There's a lot of syntax
changes, all of which are currently fixed in the current hotplug CVS.

(Other example messages:
input.agent[697]: ... no modules for INPUT product
input.agent[1489]: ... no modules for INPUT product 0011/0001/0001/ab41
pci.agent[1861]: ... no modules for PCI slot )

I don't like saying that we should upgrade to CVS, but if there's not
a new hotplug release before FC2, it might be better than spewing lots
of error and warning messages.
