I built a kernel (the 2.6.8 version that shipped with Sarge) with CONFIG_USB_STORAGE_DEBUG=y.
I then rebooted the system, waited 16 minutes, and tried to read from the disk with: dd if=/dev/sda of=/dev/null count=1 This failed with an I/O error. I have attached the dmesg output and also the output from lsusb.
