Hi all, I checkout the usb-next branch (on 2/18) and following the https://wiki.ubuntu.com/KernelTeam/GitKernelBuild to build the kernel. After reboot, the new kernel version is Linux dev 3.8.0-rc5-usbnext #1 SMP Mon Feb 18 18:04:02 CST 2013 i686 i686 i386 GNU/Linux. I try the same operation to produce the issue, and it also fails.

The device reset automatically disables the endpoints, so when usb_reset_and_verify_device calls usb_hcd_alloc_bandwidth, and that routine tries to drop the endpoints, it fails because the endpoints are already disabled. >> >> Sarah is going to to have to figure out the right way to fix this. >> She's the maintainer for xhci-hcd. >> >> Alan Stern >> > > > > -- > Best regards > Tianyu Lan > > ------Please consider the environment before printing this e-mail. > -- Best regards Tianyu Lan -- 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
