X-Git-Tag: v2.6.39-rc1~472^2~24 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aa1b13efb7cfa9f7bf4942c1e858463e335c9500;p=pandora-kernel.git xhci: Modify check for TT info. Commit d199c96d by Alan Stern ensured that low speed and full speed devices below a high speed hub without a transaction translator (TT) would never get enumerated. Simplify the check for a TT in the xHCI virtual device allocation to only check if the usb_device references a parent's TT. Make sure not to set the TT information on LS/FS devices directly connected to the roothub. The xHCI host doesn't really have a TT, and the host will throw an error when those virtual device TT fields are set for a device connected to the roothub. We need this check because the xHCI driver will shortly register two roothubs: a USB 2.0 roothub and a USB 3.0 roothub. Signed-off-by: Sarah Sharp --- Reading git-diff-tree failed
