           Summary: ohci_hcd hangs on insertion of usb device
    Kernel Version: 2.6.16
            Status: NEW
          Severity: normal
             Owner: greg at kroah.com
         Submitter: devilshawk at aon.at


Most recent kernel where this bug did not occur:2.6.15 series
Distribution:Gentoo Linux
Hardware Environment:x86, athlon-xp, via-kt400
Software Environment:
Problem Description:
The troublemaker is an Trekstor iBeat Organix device. It used to work just fine
under the 2.6.15 kernel series but since 2.6.16 the ohci_hcd driver hangs on
insertion of the device. rmmod ohci_hcd and the device works just fine with
uhci_hcd. The funny thing is that the whole usb subsystem becomes unusable on
insertion of the device. lsusb hangs, tail /proc/usb/devices hangs, removing or
inserting any other usb device during the hang does not work either, ...
After removal of the Organix everything starts working just fine again.
