I just tried upgrading everything to testing yesterday, and my printer works again (I had held libusbmuxd2 and usbmuxd at earlier versions since April to use my printer). So with: cups 1.7.5-1 libusbmuxd2 1.0.9-1 usbmuxd 1.0.8-5 everything now seems to be working. If you want to close these bugs, please feel free to do so. Julian
