I'm having considerable problems with my Archos Jukebox and my Sony Clie. They seem to have the same problem when I use them. In both instances when I install the hardware and try to load the module the modprobe hangs. The device is unusable and on previous kernels the machine would effectively lock up even though I could reboot it with the sysrq commands.
If I load the modules then plug in the devices the module loads correctly but that's about it. For readability sake I'm attaching a bzip'd logfile of the tests with the archos with all the output. If you need any additional debug output let me know. Robert :wq! --------------------------------------------------------------------------- Robert L.
