Hi,
my Delock external USB drive stopped working after updating from a
UAS-disabled distro kernel to latest 3.17-rc7 with UAS on. That UAS was
key became clear to me only after looking at storage_probe(): the device
is ignored by usb-storage if it is UAS-capable. However, nothing causes
uas.ko to be loaded when the drive is plugged here. How is this supposed
to work in the normal case?
lsusb of the device below.
