Hi list, hi Nemosoft!
Chris Cheney bugged me for a bug I submitted long ago against usbutils
package (debian), and the bug is still present, but it looks like it is
a pwc/usb-subsys problem:
PWC webcam, lsusb -v breaks:
$ dpkg -l usbutils
ii usbutils 0.11-1 USB console utilities
$ lsusb

I am using:
* debian/sid
* linux-2.4.21-pre5
plus various patches (acpi, cdrw-packet, i2c, lmsensors, extfs)
but I guess this is independent of it.
* pwc from latest kernel source, BUT NOT the latest pwc source, there
are some fixes from the website, but I also think that this
would not make a difference.
More infos:
* Epox kta3+pro
* Athlon 1400
* Modules:

Do you have any idea what may be the reason for this hang? The problem
is as follows: If someone installs hotplug (on any dist) and usbutils
then the call to usbmodules to determine the driver won't work. This is
not a big problems since usbutils/lsusb/usbmodules are not necessary for
hotplug, but if they are existent, it will break, at least on my PC
always.
