What does "...fail after a while" mean? Does it report valid values after a fresh boot and then they aren't updated after that? Created attachment 889001 [details] 0001-HID-input-disable-battery-for-0A5C-4502.patch Adding a proposed patch to fix the issue: taking the hammer, and disabling the battery property :) I just scheduled a test build here, any feedback appreciated so I can also send this upstream: http://koji.fedoraproject.org/koji/taskinfo?taskID=6770010 (In reply to Josh Boyer from comment #1) > What does "...fail after a while" mean? That it times out. It usually takes longer than those 5 seconds. > Does it report valid values after a > fresh boot and then they aren't updated after that? Never does, even using the provided keyboard. The power supply class still shows up with the new kernel: $ ls -l /sys/class/power_supply/ total 0 0 lrwxrwxrwx. 1 root root 0 Apr 24 11:04 hid--battery -> ../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1/1-1.5.1:1.0/0003:0A5C:4502.0004/power_supply/hid--battery $ uname -r 3.14.1-200.bz1090555.fc20.x86_64 #define USB_VENDOR_ID_BROADCOM 0x046e That should probably read 0x0a5c? Created attachment 889340 [details] 0001-HID-input-disable-battery-for-0A5C-4502.patch V2 Sorry for the typo in the patch. New patch and new build here: http://koji.fedoraproject.org/koji/taskinfo?taskID=6775015 Bizarrely, it's not working and the battery still shows up: $ uname -r 3.14.1-200.bz1090555.1.fc20.x86_64 $ ls -l /sys/class/power_supply/ total 0 lrwxrwxrwx. 1 root root 0 Apr 24 21:04 hid--battery -> ../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.2/1-1.5.2:1.0/0003:0A5C:4503.0005/power_supply/hid--battery *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs. Fedora 20 has now been rebased to 3.14.4-200.fc20. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those. It's obviously not been resolved. *********** MASS BUG UPDATE ************** We apologize for the inconvenience.

Tested with: kernel-3.14.1-200.fc20.x86_64 kernel-3.13.10-200.fc20.x86_64 Those are the devices shown by the builtin HID/HCI Broadcom chip: Bus 001 Device 008: ID 0a5c:4503 Broadcom Corp. Mouse (Boot Interface Subclass) Bus 001 Device 007: ID 0a5c:4502 Broadcom Corp. Keyboard (Boot Interface Subclass) Bus 001 Device 004: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth) 0A5C:4502 exports a "power supply" through its HID report descriptors, but trying to get the capacity will fail after a while: $ time cat /sys/class/power_supply/hid--battery/capacity cat: /sys/class/power_supply/hid--battery/capacity: No data available real 0m5.003s user 0m0.001s sys 0m0.001s This causes a very slow boot, as udev tries to gather information about it, and will show up in upower as well with somewhat bizarre values: Device: /org/freedesktop/UPower/devices/battery_hid__battery native-path: hid--battery model: HID 0a5c:4502 power supply: no updated: Wed 23 Apr 2014 17:05:26 CEST (22 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging warning-level: action energy: 0 Wh energy-empty: 0 Wh energy-full: 0 Wh energy-full-design: 0 Wh energy-rate: 0 W percentage: 0% capacity: 100% icon-name: 'battery-caution-symbolic' This device should be blacklisted, and its power supply support not exposed.
