 Posted: Wed Sep 14, 2016 9:07 pm Post subject: unable to Initialize libusb: -99 [SOLVED] |
 |
|
I am a new gentoo user. Brining up the system on a ASRock PRO4 H170 motherboard with 128GB M2 PCIe SSD.
The system just successfully booted.
I'm trying to isolate some mouse driver issues. I have verified that I have HID kernel support (let me know what you want me to post to verify this..it's been several hours since I did that and don't recall the specific commands/CONFIG_USB_XX CONFIG_HID_XX at the moment).
This problem is similar to the one posted at:
https://forums.gentoo.org/viewtopic-t-879569-start-0.html
But I suspect the problem is something else. I'm a newbie to gentoo.
Dustfinger posted this solution
| Code: |
# export LIBUSB_DEBUG=9
# lsusb
|
And I get the following:
| Code: |
libusb: debug [libusb_init] created default context
libusb: debug [libusb_init] libusb v1.0.19.10903
libusb: error [op_init] could not find usbfs
unable to initialize libusb: -99
|
libpci shows a host controller | Code: |
00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev31)
|
a dump of /proc/bus/input/devices does NOT show a mouse --It turns out that USB devices probably don't show up here  .
My dmesg log shows the following:
| Code: |
dmesg | grep usbfs
[ 0.1198381] usbcore: register new interface driver usbfs
|
I suspect that udev? is/has changed things such that the probing routines can't find the mouse. Thats my hunch.
As a result, the Xorg configuration can't find the mouse.
So I'd be happy if I could get lsusb to see the mouse and/or if I coudl get the mouse to show up in /proc/bus/input/devices.
Mouse works successfully from live CD -- All this proves is that I have power on and the mouse is connected via the USB port .
Oh and my code cut/pastes may have typos, as I'm posting this from an adjacent system.
Thanks!

<*> xHCI HCD (USB 3.0) support
Found this missing from my Kernel
From checking here:
https://chakralinux.org/forum/viewtopic.php?id=14008
(tetris4) mentioned missing modules could be to blame... so I followed that breadcrumb to this link:
https://wiki.gentoo.org/wiki/USB/Guide
And reviewed all my USB settings in my kernel (yet again), and found the H3.0 usb support was missing (somehow).
Rebuilt the Kernel... and VIOLA solved!
