Sharp Zaurus SL-C3000 Instruction Manual page 73

renders it to the monitor. However, the VGA application crashes after a while so it needs a bit more
work to iron out the bugs and fix the instability.
The image on the monitor remains even when rebooting
the Zaurus so I guess the last image displayed is buffered
by the USB dongle and the monitor is getting the cached
data from it.
This proves that it is technically possible to have VGA out
for the Zaurus via USB, however, the current state of the
driver and application is very limited and needs more
work. It is also very slow due to the slow USB bus speed
implemented by the Zaurus.
I then plugged the USB dongle into one of my PCs and
used it to mirror and split the display on a Win2000
system without any problems. The speed was ok there because it was using USB 2.0 High Speed
instead of USB 2.0 Full Speed that the Zaurus uses.
At this stage, the USB dongle does not perform better than displaying via a VNC server on the
Zaurus and a VNC client on a PC to display the Zaurus desktop on a larger monitor. This works fine
if you can network your Zaurus and the PC, but can't be done directly to a projector so this is where
the USB dongle could be useful. With a USB dongle you do not need a PC or a laptop to act as the
bridge device since the Zaurus can be directly connected to a projector or monitor.

Similarly, there are CF cards with VGA out capabilities similar to the USB dongle, however, none of
those cards are manufactured anymore so you would need to get them second hand if you can find
them. But even if you find those CF cards, you still need to compile drivers and applications for
them if you manage to get the driver source code so they work on the C3x00, ie 2.4.20 kernel and
glibc 2.2.2.
Connecting to Mobile Phone (SonyEriccson K750i)
recognise the manufacturer id as a mass storage device by default. To fix that, you need the
append the following to /etc/hotplug/usb.usermap:
usb-storage 0x000f 0x0fce 0xd016 0x0000 0x0000 0x00 0x00 0x00 0x08 0x06 0x50
0x00000000
usb-storage 0x0380 0x0fce 0xd016 0x0000 0x0000 0x00 0x00 0x00 0x08 0x06
0x50 0x00000000
This should make the Zaurus detect the K750i's Memory Stick as a Mass Storage device the next
time it is plugged in. However, if it does not, then try appending the above into
/lib/modules/2.4.20/modules.usbmap and/or /etc/hotplug/usb.handmap
Using Bluetooth to access Memory Stick

The Sony Ericsson K750i is a mobile phone with many features. It has a 2
mega-pixel camera, and a slot for a Memory Stick Pro Duo card. I have
upgraded mine to 1 GB. It also has Infrared, Bluetooth and comes with a USB
interface which can be used for file transfer with the Zaurus. The phone also
has a GSM modem via a serial line as well.
Using the USB cable to access the Memory Stick
The memory stick can be accessed as a mass storage device when the mobile
is connected to the Zaurus via a USB cable. However, the Zaurus does not
