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"

Here's another link I found where someone has a working version on an olpc computer.http://wiki.laptop.org/go/Adding_USB_SVGA
