Hi, thank you very much for your answer. The problem seems to be related to the ehci_hcd module, because the device is recognized if I remove this module.
Please find the requested info below: With ehci_hcd enabled: Output of dmesg: [ 7359.852048] usb 5-7: new high speed USB device using ehci_hcd and address 4 Output of uname -a: Linux 2.6.24-21-generic #1 SMP Tue Oct 21 23:43:45 UTC 2008 i686 GNU/Linux Output of lsb_release -a: Distributor ID: Ubuntu Description: Ubuntu 8.04.1 Release: 8.04 Codename: hardy Output of lsusb -v: See the attached usb.txt file. If I remove the ehci_hcd module, then the device starts to work.
