It appears it wasn't a module yet back then. out-crash: debug output form Ubuntu 14.04.1 which causes the Palm m505 to crash out: debug output form Ubuntu 9.04 which works fine probe string on 9.04 and 14.04 is different: 9.04: [ 640.784916] usb 2-2: palm_os_4_probe - length = 20, data = 01 00 00 00 63 6e 79 73 02 00 00 00 00 03 f3 5c 05 03 00 03 14.04.1: [ 1685.194594] usb 8-2: palm_os_4_probe - length = 20, data = 01 00 00 00 63 6e 79 73 02 00 00 00 01 36 00 5c 00 00 00 09 On Fri, Jan 16, 2015 at 10:10 AM, Oliver Neukum <oneukum@xxxxxxx> wrote: > On Thu, 2015-01-15 at 18:34 +0100, Henri Manson wrote: >> Hello Greg, >> >> Nothing goes wrong at the linux host, my Palm m505 shows as dialog box >> 'Fatal Exception' and hangs when the visor.ko module is loaded and >> hotsync activated on the Palm.
