A digital camera which was working fine in 2.6.11/12 now fails on 2.6.13-rc6
(not sure when it started failing).
All the messages seem to indicate that it's working but the digikam
application now says it fails to initialise the camera.
The relevant info from dmesg says:
usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: usbfs: interface 0 claimed by usbfs while 'digikamcameracl' sets
config #1
usb 3-1: USB disconnect, address 2
the only difference from previously is this:
-usb 3-1: usbfs: interface 0 claimed while 'digikamcameracl' sets config #1
+usb 3-1: usbfs: interface 0 claimed by usbfs while 'digikamcameracl' sets
config #1
dmesg difference does not show any significant difference either apart from
this:
+usbmon: debugs is not available
-drivers/usb/input/hid-core.c: v2.0:USB HID core driver
+drivers/usb/input/hid-core.c: v2.01:USB HID core driver
lsusb -v shows no difference, here is the relevant section:
