Message-ID: <1618816c0711182218o538f659ci68b8fb0680f1f38c@mail.gmail.com> Date: Sun, 18 Nov 2007 23:18:48 -0700 From: "Raymano Garibaldi" <raymano@...nos.com> To: "Denys Vlasenko" <vda.linux@...glemail.com> Cc: linux-kernel@...r.kernel.org Subject: Re: [BUG] USB_PERSIST The last time I tried this and it worked was 2.6.21. Below is a portion of the kernel log file where I had a USB storage device attached to the computer, then suspended the computer, while computer was suspended detached and reattached the USB storage device, and resumed the computer. -------------------------------------------------------------------------------------------------------------------------------- Nov 18 23:07:42 myfaun Stopping tasks ... done.
