Re: [support-gang] using usb2vga with 11.2.0 and 10.1.3
Updates: Both USB2VGA and USB2VGA2 work just fine on Build 23 on the 1.5's. Neither work on any 11.2 build from os2 to os23 on the 1.0's. I have 5 XO 1.0s on the 'test bed', and installed all of the buildsto see if any worked. None of them come up, with an external monitor. Doing the 'check-mark' boot shows they stop booting at various places, some with the USB 8 buffers assigned (13.x) line mentioned in the ticket, some with a Starting Cronds, some with a Setting Hostname line. However, to repeat, they never boot successfully, regardless of where it stops, with an adapter plugged in to any port on any 1.0 machine with any 11.2. (Must say I don't miss those multiple keychain prompts after first install on the early builds) :-) Since it seems to never work on any build, if you like, I can concentrate on just os23 on multiple XO 1.0 machines on multiple USB ports and see if there are any differences in where it halts, even if I've previously plugged it in after boot or not. I've had it get to the 3rd dot before hanging on a couple of occasions, and I think that's the time I see the 'Starting Cronds' on the console . So, if I have a more directed rather than shotgun plan, perhaps I can be more helpful. Just to be clear, i have verified that all 5 of these XO 1.0's work great with these same external adapters using Build 860 from 10.10.1.3.

Same 3 XO 1's, using os23 the external adapters work never. Not intermittently, never. The single dot is the one with the V not the one with the X. There was one weird thing, on one of the USB ports on one of the XO's it got to the third dot then the animation switched to the console and then the machine hung. For fun, plugging in the adapter after a boot, LSUSB output does show the device correctly attached to the USB2 hub. But booting with the device attached to that port is still unsuccessful. I have *not* tried the XO 1.5's yet. In this case you should boot with the check game key to (hopefully) see more info at the point of hang. http://wiki.laptop.org/go/Cheat_codes Thanks, Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

On the ticket I suggested some next steps for debugging. http://dev.laptop.org/ticket/10568 The 3rd one you can do without a serial console. See if you can reproduce it as follows: move the sisusbvga.ko file to somewhere where modprobe can't find it, boot the system and stop X. Then run a loop at the shell of insmod;rmmod, see if that makes it possible to reproduce the hang quickly More specific instructions for this: Boot without USBVGA connector attached. Go to a root terminal and move sisusbvga.ko to /root: # mv /lib/modules/*/kernel/drivers/usb/misc/sisusbvga/sisusbvga.ko /root Power off the system, connect USBVGA, boot. It should boot successfully, but without any VGA output. Press ctrl+alt+f2 to get to a root terminal, and stop X/sugar with: # stop prefdm Now load the sisusbvga driver manually and see if it hangs: # insmod /root/sisusbvga.ko Wait a few seconds, see if the system is hung or if you can still type on the console. If you can still type, unload the module: # rmmod sisusbvga and now try loading/unloading a few more times with a few seconds pause between each step. # insmod /root/sisusbvga.ko ... # rmmod sisusbvga ... # insmod /root/sisusbvga.ko ... # rmmod sisusbvga ... etc The idea is to find out whether the system hang is caused by the loading of sisusbvga. It might not hang first time, may require a few attempts, hence the repeated loading. Thanks, Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [support-gang] using usb2vga with 11.2.0 and 10.1.3
Roger that. I will try. I do have a serial adapter cable semi-permanently attached to one of the XO's - i use it to debrick any RTC machines I get off ebay., so with training, I might be able to perform those steps too later, once I get to you on the first steps.

Other tests
Folks: Still working on testing the issues with the external VGA adapters on the XO 1's, but while waiting for the flashing of the machines, in the interim I ran most of the rest of my other tests: The LDUSB-based Vernier sensors continue to work 1.0/1.5 Build 23 Sugar and Gnome. The Veho UVC USB external microscopes continue to work 1.0/1.5 with cheese on both Sugar and Gnome, Build 23. The new wizard for attaching a USB 3G modem on the Gnome side1.0/1.5 is brilliant. Just plugged the little Sierra Wireless stick in, waited for it to be shown as recognized by lsusb, then ran the wizard from the network icon drop-down. I used defaults for Rogers here in Canada, and it connected first time, and reliably every time after that! Haven't tried that on the Sugar side. Have not done the guvcview testing or cups HP printing tests, anywhere, yet. Last but not least, on networking, WPA2 to Airport and Cradlepoint, and USB wired-ethernet adapters to router work 1.0/1.5, Gnome and Sugar, Build 23.

However, it needs to be an easy GUI feature. Anything that requires a terminal is far beyond what we can expect a teacher or child to do. I have recommended the Midnight Commander file manager for this purpose. sudo yum install mc It is a full-screen character-mode program that runs in Terminal, so it needs no Sugarizing. Among its features are sorting, filtering, selecting multiple items or groups of items, and two-click copying or moving of selections, whether files or whole directories. We would need to write some lesson plans in order to give this to children. MC is not suitable for copying to and from the Journal, but it handles everything in plain files, and simplifies using the scripts given on the page you referenced. See also http://booki.flossmanuals.net/command-line/edit/ written for the Free Software Foundation. (I am one of the authors.) Unlike conventional command-line textbooks and manuals for those planning to be developers or sysadmins, this describes only what users need to know. It is not directly suitable for young children, but again we could use it as the basis for lesson plans.
