"unable to initialize libusb: -99" error in udoo quad

[tuxx]

Hi all,

I have started experimenting with linux-armv7 on my udoo quad.

I used latest image of 01/06, updated to latest packages and installed linux-armv7 along with uboot-udoo-quad.

The system boots but usb devices are not recognized. When i give lsusb, the output is:

$this->bbcode_second_pass_quote('', 'u')nable to initialize libusb: -99

USB works with 3.15 mainline, if you update the DTS files for Udoo Quad.

git://git.kernel.org/pub/scm/linux/kern ... /linux.git
89de473 ARM: dts: imx6q-udoo: Add USB Host support

I did a clean installation and usb works fine. I assume there was an update in kernel or something like that.

Which kernel you are using?

linux-armv7 from Archlinuxarm repositories.

Ah ok, this kernel is modified and not an unmodified kernel.org mainline one.

The PKGBUILD (https://github.com/archlinuxarm/PKGBUIL ... 7/PKGBUILD) uses
"http://rcn-ee.net/deb/sid-armhf/v${pkgver}-${rcnrel}/patch-${pkgver%.0}-${rcnrel}.diff.gz"

I looked at:
http://rcn-ee.net/deb/sid-armhf/v3.15.0 ... x2.diff.gz

There is the patch for the UDOO dts file included.

I thought with mainline not an ArchLinuxARM one, but the official one.
If you mean an unmodified ArchLinuxARM one, ok...
