Just tested 014b45d9 with an EPSON ES-H300 and the epson2 as well as
epson backends.  SANE backends configured with

  ./configure --enable-libusb_1_0

I had no trouble scanning three times in a row with scanimage using
either backend with the scanner connected to a bus controlled by the
xhci_hcd driver.  So your changes didn't break anything for me :-)

Tested on Debian GNU/Linux jessie (last updated 2014-12-16), running
with linux-image-3.16.0-4-amd64.

Hope this helps,
