Is this stock Raspbian or another variant?

If it is Raspbian, I think it might be affected by a Debian issue with
libusb-0.1. It is possible to rebuild from source and use libusb-1.0 instead -
let us know if that sounds reasonable. You can also check the list archives for
previous discussions (although I think we were seeing issues with Tripp-Lite
hardware more frequently).

Also, sometimes swapping out the USB cable can help.
