I have a wireless bluetooth keyboard (a Logitech diNovo ultra-flat, about seven years old) that I love. Every time I update my Ubuntu installation there’s a ~50% chance that it’ll stop working, and on the update to 15.10 that I just did I got unlucky.<\/p>\n

To get it working again I had to comment out the following two lines in \/lib\/udev\/rules.d\/97-hid2hci.rules<\/code> and then reboot.<\/p>\n

KERNEL==\"hiddev*\", ATTRS{idVendor}==\"046d\", ATTRS{idProduct}==\"c70[345abce]|c71[3bc]\", \\\r\n\u00a0 RUN+=\"hid2hci --method=logitech-hid --devpath=%p\"\r\n<\/pre>\n
I’ve had to do something similar on more than one previous occasion. The idea originated here<\/a>, but note that the name of the rules file has changed since that was written.<\/p>\n
(When I updated to 15.04 this problem did not<\/em> manifest. However, I got unlucky and the batteries in the keyboard died while the update was occurring. Batteries in this keyboard typically last 4–5 months, and diagnosing dead batteries is normally easy — hey, the keyboard stopped working suddenly! — but because Ubuntu updates had caused troubles with this keyboard in the past I assumed the update was the cause. I didn’t think to try new batteries until I’d spent a couple of tedious hours deep in the bluetooth configuration weeds. Lesson learned.)<\/p>\n","protected":false},"excerpt":{"rendered":"
