This happens on my desktop with ubuntu 16.10 (Kernel 4.8.0-27) and my laptop (kernel 4.4.0-38) NO USB3 hardware is involved in my case, both machines have USB2-ports only, lsmod does NOT show and xhci modules loaded. I tried the command SANE_DEBUG_AVISION=8 SANE_DEBUG_SANEI_USB=5 scanimage > scanfehlerxx.txt and produced the files attached. The key statement might be: [sanei_usb] sanei_usb_read_bulk: trying to read 61054 bytes [sanei_usb] sanei_usb_read_bulk: read failed: No such device (it may have been disconnected) [avision] read 0 bytes [avision] No data arrived. This error occurs as well with Fedora 24, but NOT with debian 8.6. So it may be related with the more recent kernels and their behaviour on the USB ports.
