Sugar does not see/mount USB Flash drive

[mungewell]

Binary package hint: sugar

When inserted a USB Flash key is not seen by Sugar/Sugar-Emulator (it should show up the bottom bar of Journal, see http://en.flossmanuals.net/Sugar/BackingUp), instead the USB Flash drive is mounted by the underlying OS.

At a (wild) guess there will need to be some HAL tinkering to ensure that Sugar gets notified and the underlying OS does not.

The OS should still automount, as this is what happens on the XO. In
addition to this, sugar should detect the mounting and add the device
to the journal.

After lfaraone said it worked for him, I tried a few couple of different USB sticks, both worked OK but the original one still failed.

Lexar 1GByte - worked, mounted first partition of 2 (sdb1 = VFAT) and displayed the contents of /media/LEXAR/syslinux (yes this is a Fedora bootable USB of Sugar ;-)
Unbranded 2GByte - worked, mounted first partition of 2 (sdb1 = VFAT) and displayed the contents of /media/live/casper (bootable Ubuntu Sugar)
Sandisk Cruzer 4GByte - failed. 1 partition (sdb1 = VFAT), USB-ID 0x0781:5406

Maybe this is just a problem with larger size USB drives, or with Sandisk specifically.

Couple of points

1). I am an idiot. The Sandisk is only 512MByte version, so it unlikely to be an issue with large disks.

2). If I insert a 'working' USB key with sugar-emulator running it is sometimes mounted UID=1000 (my user ID) and sometimes mounted UID=500. There seems to be a race condition here somewhere. Regardless of UID it appears in the Journal.

3) The Sandisk shows the same 500/1000 issue with sugar-emulator, but still doesn't appear in the Journal.

4) Without Sugar-emulator running they both always (so far) mount as UID=1000.

Sandisk HAL listing does not include the correct HAL properties, and thus fails the test in /usr/share/activities/Journal.activity/volumesmanager.py

This is most likely a HAL problem.
