Update: rather than power off, I decided to do another ctl-alt-f2 at the snag of the 'stall point' below, and got a bash prompt, entering stop prefdm there then returns unknown instance and a bash prompt tried the insmod tests from there, loaded successfully with the following output: usb 1-2: USB2VGA dongle found at address 3 usb 1-2: Allocated 8 output buffers usb 1-2: 8Mb 1 ch/1 r SDR SDRAM, bus width 32 usbcore: registered new interface driver sisusb tried the rmmod, got the following output: usbcore: deregistering interface driver sisusb did it about 10 times with various 1-10 second waits before and after each step, always results as above.

Re: [support-gang] using usb2vga with 11.2.0 and 10.1.3
Last update for today, promise :-) On a fresh install of os23 on any of my XO 1.0's, (without moving the .ko driver) with a VGA adapter , doing this first time try booting using 'boot' from OFW, the system will most often hang on the set localhost line right after the [13.xxx] 'Allocated 8 output buffers' USB line. If it hangs right here, if I now unplug the VGA adapter it continues to boot. If instead, the console lines on an OFW boot continue through the [14.x] and hang on the diisplay of libertas lines, then removing the VGA adapter does not cause the boot to continue. It sits there unhappily idle. So bottom line ruight now is that the 'workaround' for the intermittent problem listed as in the ticket does not carry forward to 11.2. I cannot get it to give VGA outputon an XO 1.0 on build 11.2, at all. External power is in, and the VGA display is ready for all the above tests. Awaiting more orders.

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.

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.

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.

I will work back in builds to see when it stopped working. It looks to me like not only the sisusb, but also the ldusb devices, are unhappy with this kernel. I will inform daniel and martin. On mine, it stops loading with only one of the little progress dots on the animated start-up displaying either going to gnome or sugar. This might officially be a 'regression bug';, but, I'll probably neeed some input from D and M as to how to do a non-animated boot so I can see any errors and then do an official report. :-) Also, unfortunately way back in the 11.2 builds, the usb utilities which include the lsusb command are no longer shipped. You have to install it manually by going to terminal, doing the 'su' then doing 'yum install usbutils'. I had mentioned this before in the developer forum, it's really small, and I'm not sure why it's not included anymore, but alas it is not.

First results, and I do apologize but I wont have any more time until tomorrow to test further 3 different XO's: USB2VGA and USB2VGA2 work first time everytime using build 860. 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.

I have *not* tried the XO 1.5's yet. Also, maybe a false alarm on the LDUSB, it's kicking an error, but the sensors still seem to work. Also, the external microscopes look like they work too. In both of those cases, one plugs in the device *after* boot though. I'll start working my way up the 11.2 builds to see if/when the External VGA started or stopped working. But unfortunately, it will be tomorrow Cheers KG On Sat, Jun 18, 2011 at 5:30 AM, Daniel Drake d...@laptop.org wrote: On 18 June 2011 09:43, Kevin Gordon kgordon...@gmail.com wrote: Cherry: I too am having troubles with both the USB2VGA and USB2VGA2 on build 23 with the XO1.
