I cant find any mention of quirks for the Intel USB controller PCI IDs but I might be looking in the wrong place, do you have a link to what I should be searching though? I did however find the following which is for the exact device I'm having issues with and seems to indicate the HW might have an issue with HighSpeed mode. https://lkml.org/lkml/2012/4/19/224 http://lkml.iu.edu//hypermail/linux/kernel/1204.3/03115.html Which makes me wonder if hw.usb.ehci.no_hs=1 would also result in a working device.
