I have problems with Samsung SCX-3205 scanner on Toshiba Satellite L855. When is scanner connected to the notebook (via USB) I can see it via `scanimage -L` on first attempt but on any other attempt I can't see it any more, unless I turn the scanner off and on. Currently using 3.5.3-1.fc17.x86_64 kernel (but it also happens with 3.6.0-0.rc4.git2.1.fc18). The latest working kernel is 2.6.39-1.fc16 on that hardware (2.6.40 which was in fact 3.0, I guess, does not work). That scanner with identical OS - Fedora 17 - worked well on Lenovo T510 (Sandy Bridge -- USB 2.0 only), the new Toshiba L855 (Ivy Bridge with USB 3.0 -- xHCI) fails here. I somehow think it's related to the xhci driver, hence Cc-ing Sarah. Is there a way how to disable xhci driver in favor of ehci (xhci and ehci are both compiled-in), so I can try with ehci? lspci & lsusb logs in the kernel.org Bugzilla. Keep me Cc-ed, I am not in the m-l.
