Connected scanner and started xsane.
Same issue here, with a laptop that has only USB3 ports; while my scanner doesn't seem to work properly when using this protocol.

A workaround I found, was setting up a virtual machine (both VirtualBox and VMWare [player] should be ok) with any *linux* distro you want, I configured it to be compatible with USB 2.0 protocol. Once I redirect my USB device to the VM I can scan from there. I'm wondering why it's not possible to simulate the same in the host. The VM in fact uses ehci-pci: [ 1145.397337] usb 1-1: new high-speed USB device number 2 using ehci-pci [ 1145.831386] usb 1-1: New USB device found, idVendor=04e8, idProduct=3441 [ 1145.831389] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1145.831404] usb 1-1: Product: SCX-3200 Series [ 1145.831405] usb 1-1: Manufacturer: Samsung Electronics Co., Ltd.
