Title:
  Samsung UpStage Phone USB Mass Storage not accessible

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: linux-image

  Probably similar to other usb bugs posted, but it seems that a bug for this particular device
  has not been reported yet.

  Mass Storage on my Samsung Upstage Phone (MPH-620) was recognized and automounted  under Ubuntu 7.04 (running the 7.04 LiveCD on my system) but access is broken on 7.10 (installed).
  This is running off a usb 1.1 port so the ehci_hcd issue shouldn't apply here.

  The dmesg output after the phone is connected and put in mass storage
  mode is:

  Running on the same system on the ubuntu 7.04 live CD, the output is:

  The phone's usb mass storage is available and automounts.  Reading/writing is fine.
  Not so under ubuntu 7.10

  WORKAROUND: I modified
  /etc/udev/rules.d/65-persistent-storage.rules
  in the following way:

  Beginning near line 60 I commented out : IMPORT{program}="vol_id
  --export $tempnode"

  And replaced with: (1 line)
  ENV{DEVTYPE}!="disk", ENV{ID_VENDOR}!="Samsung", ENV{DEVNAME}!="/dev/sdb",
  IMPORT{program}="vol_id --export $tempnode"

  After rebooting, now the USB storage on my phone is accessible.
