I'm having trouble getting my iPod working under Centos 4. I was hoping someone else using their iPod with Centos 4 could shed some light on this.
When I attach my iPod via USB, I get these messages: 19:36:44 brahma kernel: usb 1-8: new high speed USB device using address 2 19:36:45 brahma kernel: Initializing USB Mass Storage driver... 19:36:45 brahma kernel: scsi2 : SCSI emulation for USB Mass Storage devices 19:37:35 brahma kernel: usb 1-8: reset high speed USB device using address 2 19:37:51 brahma kernel: scsi: Device offlined - not ready after error recovery: host 2 channel 0 id 0 lun 0
I had no problems getting my iPod to work under Centos 3 (2.4.x kernel), once I had recompiled without the EFI partition option. In this case I don't think EFI is a factor though, as the device isn't even making it to the partition scanning stage.
I tried using just the slower uhci_hcd but got the same results. Then I tried using the latest FC3 kernel (2.6.11-1.35_FC3), and surprise, the iPod mounts (with ehci) without any problems.
Obviously I'd prefer to run the RHEL/Centos kernel though, even if it requires a small patch. At least then I know what's changed.
