Description:
When I connect my Moto G2, I am getting the following error in dmesg or the system journal.

kernel: usb usb2-port1: unable to enumerate USB device

Using the following commands as per the wiki (https://wiki.archlinux.org/index.php/MTP) fixes the issue.

# modprobe -vr uhci_hcd
# modprobe -va ohci_hcd
# modprobe -va uhci_hcd

However, adding the the following to /etc/modprobe.d/usb_hci_order.conf as suggested in the wiki does not work.

# create a dependency on ohci for uhci, which fixes problems
# with external usb devices not showing up
#
softdep uhci_hcd pre: ohci_hcd
This task depends upon

Can you reply back with an update on whether or not this is still a problem? This may have been fixed in a more recent kernel. If this is still occuring please provide the kernel versions you have tested it on or any other information you have. Waiting on your response.
