Fadeeva Marina <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #23 from Fadeeva Marina <[email protected]> --- Hi all, I've also faced with the same problem. Recent 3.17-rc7 kernel doesnt detect USB controller at all on Acer ICONIA W510. With David's patches (http://git.o2s.ch/?p=linux-stable.git;a=shortlog;h=refs/heads/v3.15-z2760) the cotroller is seen, but device enumeration fails. Same thing with earlier (3.15 and 3.16) kernels. If someone have any ideas on this to try I'm ready to test.
