Ah, I missed that one which you already sent out a v3 still applying perfectly: http://article.gmane.org/gmane.linux.ports.tegra/25396 With that it looks much better again: ubuntu@tegra-ubuntu:~$ lspci 00:02.0 PCI bridge: NVIDIA Corporation TegraK1 PCIe x1 Bridge (rev a1) 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c) I also found a more capable test device: ubuntu@tegra-ubuntu:~$ sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 576 MB in 3.01 seconds = 191.55 MB/sec However on Apalis TK1 this broke the second USB 3.0 host port which now refuses to work. Still works plugging in USB 2.0 gear though. Hm, it works if plugged in during boot. Strange. What could be the issue if hot-plugging USB 3.0 devices on the second port does not quite work? I'm also wondering whether the Tegra EHCI stuff is still required as there are now quite many USB buses showing up: ubuntu@tegra-ubuntu:~$ lsusb Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 002: ID 174c:07d1 ASMedia Technology Inc.

Thanks for testing. Thank you. BTW: Does any of you make it to GTC this year? I will attend and Toradex is showcasing its latest Apalis TK1 module. > Thierry Cheers Marcel -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
