Yes... http://marc.info/?l=linux-usb-devel&m=118598561010046&w=2 However, I have not tested this with a VIA EHCI controller (though it's been tested with Intel, Broadcom, and nVidia). This patch uses the "inactivate" bit in the QH, which wasn't previously used by the linux kernel, and I found that the different vendors of EHCI controllers (Intel, Broadcom, nVidia) all handle this a little differently. There's probably something about the way VIA controllers respond to seeing this bit set that is breaking things. I'll try to get my hands on a VIA EHCI controller so I can look at this... if you happen to know of an add-in card that has one of these, please let me know! It would be a lot easier for me to debug this myself here than to try to get someone else to run test kernels for me... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
