            Bug ID: 46491
           Summary: "harddisk_ioctl Unsupported ioctl 2d0c00 (and 4d004)"
                    breaks Olympus camera firmware updater
           Product: Wine
           Version: 4.0-rc7
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mountmgr.sys
          Assignee: wine-bugs at winehq.org
          Reporter: bero at lindev.ch
      Distribution: ---

The Olympus camera firmware updater
(http://support.olympus-imaging.com/ou1download/) installs correctly, but fails
to detect the camera.

The camera is supposed to be connected in USB storage mode (that works overall,
I see the camera as drive f: in "wine explorer.exe"); chances are the firmware
updater would work if only it could identify the camera correctly instead of
seeing it as some generic storage device.

While probing for the camera, wine says

0019:fixme:mountmgr:harddisk_ioctl Unsupported ioctl 2d0c00 (device=2d access=0
func=300 method=0)
0019:fixme:mountmgr:harddisk_ioctl Unsupported ioctl 4d004 (device=4 access=3
func=401 method=0)

I don't know anything about Windows IOCTLs, but I suppose those read a hardware
identifier?
