I had some issues with USB3 with an ASMedia controller the first time I
tried using it.  I didn't need USB3 on the machine and moved my device to
a USB2 port and had no issues.  I have never tried the port again since.
I have used USB3 on my laptop in linux and the intel USB3 works fine.
I am not sure how good those ASMedia controllers really are.

You are using the USB3 cable I would assume.

Have you tried on a box with a different USB3 controller type?

http://marc.info/?l=linux-usb&m=134236551409964&w=2 for example mentions
the ASM1042 has known bugs.
