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 Bus 002 Device 001: ID 0000:0000 Bus 002 Device 002: ID 0471:0308 Philips PCVC680K WebCam [pwc] Bus 002 Device 003: ID 03eb:3301 Atmel Corp. 4-port Hub Bus 002 Device 004: ID 046d:c207 Logitech, Inc.

More infos: * Epox kta3+pro * Athlon 1400 * Modules: ... joydev 6112 0 (unused) pwcx 86272 0 (unused) pwc 44328 0 [pwcx] videodev 6144 1 [pwc] mousedev 4404 1 usb-storage 24368 0 hid 19364 0 (unused) uhci 27056 0 (unused) usbcore 64224 1 [pwc usb-storage hid uhci] ... 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.
