The patch didn't help, obviously... You're still getting these errors, and I still think they look like low-level hardware errors. It wouldn't be surprising if the same errors occur when you use the player with Windows -- maybe Windows is just better at recovering from the errors when they occur. It would be interesting to see a log of the Windows USB activity. It is possible for you to create such a log, using a program like usbsnoop. See <http://sourceforge.net/projects/usbsnoop/>. There is a patch to improve the error recovery in Linux. However it will only apply to 2.6.12-4; it won't work with a 2.6.11 kernel. Most likely that means you won't want to try it out until you have a lot more free time. There's one other thing you can try easily. Maybe the ub driver will work better than usb-storage. You can find it in menuconfig under Device Drivers / Block devices / Low Performance USB Block Driver. To use it all you have to do is rmmod usb-storage and modprobe ub.
