A simple list of working and nonworking devices: Works: * Logitech MouseMan Optical Dual * Apple Pro Keyboard * Iomega ZIP 100 Works not: * TerraCAM USB Pro: (ov511 v2.28) drivers/usb/media/ov511.c: init isoc: usb_submit_urb(0) ret -38 * USB-to-Serial (pl2303) pl2303_open - failed submitting interrupt urb, error -28 Perhaps a driver programming bug?
