| Subject: xhci: Disable streams on Asmedia 1042 xhci controllers |
| |
| From: Hans de Goede <hdegoede@redhat.com> |
| |
| commit 2391eacbd00b706ff4902db7dbee21e33b6f1850 upstream. |
| |
| Streams seem to be broken on the Asmedia 1042. An uas capable Seagate disk |
| which is known to work fine with other controllers causes the system to freeze |
| when connected over usb-3 with this controller, where as it works fine with |
| uas in usb-2 ports, indicating a problem with streams. |
| |
| This is a bit bigger hammer then I would like to use for this, but for now it |
| will have to make do. I've ordered a pci-e usb controller card with an Asmedia |
| 1042, once that arrives I'll try to get streams to work (with a quirk flag if |
| necessary) and then we can re-enable them. For now this at least makes uas |
| capable disk enclosures work again by forcing fallback to the usb-storage |
| driver. |
