I have Lucid (10.04 LTS) and I confirm the problem. I can precisely describe the hardware in question, it is a PCI Express USB 3 card by manufacturer Delock. It uses the VIA VLI 800 chipset. Hard disks in USB-3-to-SATA adapters are only detected upon boot time. Rarely a plug&pray detection works, but then only once, not twice. Detection of a drive can be forced with rmmod xhci; modprobe xhci.
I also see numerous "WARN: short transfer on control ep" and "WARN: Stalled endpoint", but no buffer errors. I suspect there might be a 64 bit issue behind this, and both on the side of the xhci kernel module, and the hardware (or the firmware - yes, this VLI chipset does have a firmware of it's own). The card runs absolutely perfect under Windows XP 32 Bit with the enclosed Windows driver V 1.40a. It also runs flawlessly under Windows 7 32 Bit. But under Windows Vista 64 Bit I get bluescreens of death upon each and every boot, even in safe mode. And that also applies to drivers version 1.50 and 1.90, so I suspect there is a compatibility issue underneath. My kernel is a 2.6.32-42 - that is the latest that Lucid will install by itself. Lucid is still not declared dead. Yes, I know that there is Precise, and a point release has been issued. But migrating to Precise is no option for me as long as it forces me to use Unity, but that's another story. Is there a way to move to a kernel 3 without breaking thousands of things? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/647973 Title: USB 3.0: xhci_hcd WARN: Stalled endpoint To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/647973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
