I installed usbip:

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -ivh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
yum install usbip-utils

Then I tried to load drivers:

modprobe usbip_core
modprobe usbip_host
modprobe: FATAL: Module usbip_host not found.

This sound strange. The module seems to do not exist. I tried to use usbip anyway:

usbipd -D


usbip list -l - busid 3-1 (04e6:5116) SCM Microsystems, Inc. : SCR331-LC1 / SCR3310 SmartCard Reader (04e6:5116)

  • busid 3-14.1 (0557:2419) ATEN International Co., Ltd : unknown product (0557:2419)


usbip --debug bind --busid=3-1
usbip: debug: usbip.c:141:[run_command] running command: `bind'
usbip: debug: sysfs_utils.c:17:[write_sysfs_attribute] error opening attribute /sys/bus/usb/drivers/usbip-host/match_busid
usbip: debug: utils.c:47:[modify_match_busid] failed to write match_busid: No such file or directory
usbip: error: unable to bind device on 3-1

doen't work. looking around it seems that usbip_host is missing. But I cannot load it because seems to be not shipped with usbip package.

I'm stuck

I just realised that the issue was in this answer:

USBIP on CentOS 7

Which there was a typo in the installation of kmod_usbip:

yum install ksmod-usbip
yum install usbip-utils

the first line is wrong. The module is just kmod not ksmod. The right command is:

yum install kmod-usbip

I'm gonna to fix original question
