Hi, I've been having issues with uas (usb attached scsi) drive that is connected to a pci passed-through xhci controller (ASM1142). The drive hangs and cannot really be used. The combination seems to work fine on bare-metal. bot/msc drives work fine.
I tried to install the XHCI driver from ASMedia to see if it makes a difference. It ends up disabling uas. Not sure if that would happen on bare-metal as well. I saw https://github.com/torvalds/linux/commit/ec37198acca7b4c17b96247697406e47aafe0605 today and I wonder if vfio-pci needs to be "notified" as well. Never tried passing through another XHCI controller. Can anyone confirm the issue is vendor/device-specific? Any idea on how to further debug this?
