I took usb-linus branch (up to 7a3c296ae08f), I checkedout git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git and built. build was done using make deb-config LOCALVERSION=-khan DEB_PKGVERSION=$(make kernelversion)-1 uname -a Linux pc 4.15.0-rc3-khan #1 SMP Sun Dec 17 21:00:45 IST 2017 x86_64 GNU/Linux my usbip config settings are : grep USBIP /boot/config-4.15.0-rc3-khan CONFIG_USBIP_CORE=m CONFIG_USBIP_VHCI_HCD=m CONFIG_USBIP_VHCI_HC_PORTS=4 CONFIG_USBIP_VHCI_NR_HCS=8 CONFIG_USBIP_HOST=m CONFIG_USBIP_VUDC=m Thanks ! -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
