2  General Category / Success stories / Using the plug as a full PC with an external display (usb2vga) on: June 13, 2009, 06:01:27 PM
I got my usb2vga adapter working with the plug, here's a video of it all working:


sheevaplug+sdcard+usb2vga adapter+keyboard+mouse.

I had to recompile the kernel to add support for the sisusb driver.  Then installed xorg + gnome + firefox and added the appropriate entries to xorg.conf.  It's not the speediest PC in the world, but it's definitely usable.  Would work well for email+web browsing. 

I'm using the StarTech.com USB 2.0 to VGA Dual Display Adapter, but any usb2vga adapter which uses the sisusb driver would work.  Price for the adapter is around $60-$80.

I'm trying to get a starcom usb2vga device working on the plug.  This device uses the sisusb driver, which unlike the displaylink devices is fully supported in Linux with an Xorg driver (see: http://www.winischhofer.eu/linuxsisusbvga.shtml). 

I think the problem that I'm having (but I'm not sure) is that the driver isn't compiled into the kernel that I'm using, I'm using the orion kernel 2.6.30-rc6 (from here http://plugcomputer.org/plugforum/index.php?topic=298.0).   I have a fully working gnome desktop running which I am able to vnc into, but I'd like to go a step further and get an external monitor working, I've been able to get the device working on a couple of other Linux PC's pretty easily.  But I realize that those machines have much more stuff loaded into their kernels.  Any help would be greatly appreciated.

Here's what I see so far:

I have the xserver-xorg-video-sisusb driver installed.

When I plug in the device, and do lsusb, I get:

Bus 001 Device 003: ID 0711:0900 Magic Control Technology Corp. SVGA Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root

But lsmod doesn't show the device as loaded:

Module                  Size  Used by
ipv6                  266168  10
dm_crypt               14084  0
dm_mod                 59152  1 dm_crypt

My kernel.log shows:

Jun  6 18:30:30 lallafa kernel: usb 1-1: new high speed USB device using orion-ehci and address 3
Jun  6 18:30:30 lallafa kernel: usb 1-1: configuration #1 chosen from 1 choice

When I do startx I get the following:

(II) LoadModule: "sisusb"
(II) Loading /usr/lib/xorg/modules/drivers//sisusb_drv.so
(II) Module sisusb: vendor="X.Org Foundation"
   compiled for, module version = 0.9.0

(II) SISUSB: driver for SiSUSB chipsets: SIS315E/PRO USB
(WW) Falling back to old probe method for v4l
(WW) Falling back to old probe method for sisusb
(EE) No devices detected.

Here's another link I found where someone has a working version on an olpc computer.

Worked great for me, and saved my butt, I was getting CRC errors on the nand drive, and now I can boot it of SD.  Thanks, it's a great utility and is really easy to use.
