Same problem for me using Ubuntu Zesty (17.04) I noticed two different types of error: The first one has error code -71, and I don't know what does it means:
Jul 15 10:15:17 achille kernel: [ 202.060450] usb 3-14: new full-speed USB device number 14 using xhci_hcd Jul 15 10:15:18 achille kernel: [ 202.800931] usb 3-14: unable to read config index 0 descriptor/all Jul 15 10:15:18 achille kernel: [ 202.800934] usb 3-14: can't read configurations, error -71 The second one has code -110, which seems to be related to a current drain problem: Jul 15 10:15:24 achille kernel: [ 209.099650] usb 3-14: new full-speed USB device number 16 using xhci_hcd Jul 15 10:15:30 achille kernel: [ 214.483027] usb 3-14: unable to read config index 0 descriptor/all Jul 15 10:15:30 achille kernel: [ 214.483029] usb 3-14: can't read configurations, error -110 This USB keyboard has two USB plugs, one for data and one for power. I connected both of them to different USB ports in order to have enough power, but the problem persists. No problems occurs during UEFI boot, on Grub menu and using other Linux distributions (some tests on Slackware and Debian, but only for few minutes on "live boot"). Even Windows seems to have no problems. Can it be some power management problem of ubuntu linux kernel? During boot (after Grub), the keyboard leds shut off until all kernel modules are loaded. After that there are two possible behaviours: everything works fine, or keyboard doesn't works and you have these messages on syslog. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1678477 Title: Kernel has troule recognizing Corsair Strafe RGB keyboard Status in linux package in Ubuntu: Confirmed Bug description: I recently bought a Corsair Strafe RGB keyboard, and while it works well when successfully recognized by Ubuntu at boot, that doesn't always happen. I see messages like this when booting my desktop up: [ 6.619510] usb 3-10: unable to read config index 0 descriptor/all [ 6.619543] usb 3-10: can't read configurations, error -110 They sometimes repeat at 5-second intervals, culminating on a "can't set config #1" message or even "unable to enumerate USB device". This happens on the logic that deals with a new USB device being connected, so when it doesn't work it never gets to the HID drivers part of the code. When it does, hid-generic is quite able to control the keyboard, though this message appears on dmesg: [ 6.883811] usbhid 3-10:1.2: couldn't find an input interrupt endpoint From what I have been able to determine, the Corsair Strafe RGB has three inputs, with the last one being used as input/output and having something to do with the LEDs. It only has a single USB configuration, though I don't know why it times out. Searching on Google has a lot of people recommending this userspace drive to me: https://github.com/mattanger/ckb-next , and I've tried it, but it seems to be more about programming lighting effects into the keyboard than in controlling its basic operation, which is all I'm interested in. Its daemon was supposed to handle that part too, but it didn't fix those connection errors on boot. I have the following boot parameter set in my kernel, following advice from ckb-next's README, but it doesn't see to have an appreciable effect on my success rate: usbhid.quirks=0x1B1C:0x1B20:0x20000448 ckb-next recommended 0x20000408, but I added the HID_QUIRK_MULTI_INPUT as well in an attempt to improve things, without success. GRUB is always able to correctly identify the keyboard and get it to work, too, which makes the fact that the full kernel can't always do it a little more frustrating. I would be happy to provide any extra information you require on this issue.
