Acer A500 internal storage is not auto-mounted by Ubuntu I just got my Acer A500 and have problems accessing the it's storage from my ubuntu machines.

If I try it with Win7 in VirtualBox it is automatically mounted without requiring any actions on the tablet itself.

Ubuntu accepts the USB device (it can be passed to vbox) but nothing further. The only dmesg entry is:

[119174.117100] usb 1-1.2: new high speed USB device using ehci_hcd and address 22


I'm able to mount and use other usb storage devices.
On Ubuntu, your device needs to be manually identified to the udev system:

As root:
Create or edit /etc/udev/rules.d/51-android.rules and add this line:

SUBSYSTEM=="usb", SYSFS{idVendor}=="0502″, MODE="0666"


Then:

# chmod a+rx /etc/udev/rules.d/51-android.rules
# restart udev
udev start/running, process 3793


This works for my Sidekick on my Ubuntu 10.04 system.
