[Linux-uvc-devel] [PATCH 1/2] USB: EHCI: Move sysfs related bits into ehci-sysfs.c

2011-06-24 Thread Kirill Smelkov

Hello laurent: You propose to me: Try to upgrade to a recent kernel. 2.6.14 is more than 5 years old. It isn't possible to use a newer/newest kernel. I tried to compile different versions of kernels (2.6.18, 2.6.20, 2.6.22, 2.6.242.6.38 ) and basically is impossible for some reasons: 1)
