Hi.

I just got a brand new Xperia Arc running Android 2.3 (Gingerbread). I also run 10.10 on an iMac. Usually I don't have any problems connecting usb devices to the iMac. My old Nokia N86 connected without problems (as a USB disk). Now, when I connect the Arc to the iMac I get:


[535484.028139] usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd gvfs-gphoto2-vo rqt 192 rq 8 len 1000 ret -110
[535484.033234] scsi 12:0:0:0: CD-ROM SEMC CD-ROM 0100 PQ: 0 ANSI: 2

[535544.024045] usb 1-1: reset high speed USB device using ehci_hcd and address 17


Then after a while I get a popup "Media player device error Unable to open the (null)(null) device"

I tried to connect the Arc to a Win 7 machine and it popped up as an USB drive without problems.

Any thoughts?

Thanks in advance,

I just got the same problem and found your post here :)

I noticed my Xperia arc was configured to use MTP mode when connected to a usb host. I changed it to MSC and the problem was solved. If you are ok with MSC mode, you could do the same.

1. Go to Settings-> Sony Ericsson -> Connection
2. Tap USB connection mode and choose MSC

Note: The above menu item names could be different on yours since I'm using it in Japanese language.

I tried that solution with my Xperia Arc but I am still not having any luck. I have it in MSC mode but it doesn't pop-up as a flash drive or anything. The disk utility can see a SEMC Mass Storage device but it cannot see the media.

Any thoughts?

Here's what you need to do:

(Before you do this, take note that apps that were moved to SD will disappear as the SD card needs to be unmounted!!!)

To mount:

1. Connect the device via usb
2. Go to notification, Set the USB connection mode to MSC (SEMC should pop up)
3. Again in notification > connect phone memory card (this step will unmount your SD card).
4. Wait until the notification in the device tells you that the phone memory card is connected. After that, the SEMC storage can now be accessed.

To unmount:

1. Go to notification > phone memory card connected > disconnect
2. Wait till a notification is received, your apps should return as usual

This works with ubuntu lucid version

Hope this helps!

SAME Menu and THANK YOU... it worked for me!!!
While still plugged in, I changed to MSC and right away the connect message came up in UBUNTU.
Thanks Again!

Changing MTP to MSC will do nothing unless you haven't installed Wine. Use Ubuntu Software Center to install it. Then you change USB connection mode to MSC in your phone settings and check PC companion. Ubuntu recognized my Sony Ericsson Experia Arc S after I did that.
