wgrantIs there any chance of seeing a more recent aufs in Jaunty's kernel? I see something on the ML about recent versions of aufs1 requiring changes to build with 2.6.28, but I have custom kernels with it working fine.03:39

kjdrohttp://paste.ubuntu.com/128181/12:04
kjdrothis is lspci12:04
kjdroyeah well12:05
kjdroin dmesg you could see a lot of:  usb 8-1: reset high speed USB device using ehci_hcd and address 412:05
kjdrowhat specificly interest you so i use grep ...12:06
kjdroor if you want all i could redirect output to a file 12:06
kjdrowitch is it ?12:07

kjdroas i sad... :(12:08
kjdrosome 2 pages of that ore more in the full output of dmesg12:08
kjdrowell .. about the forum.. i read now.. well... kinda lack the time... right now.. 12:09
kjdromy copy is at 41%.... since 9:00 am this moring .. now it's 14:0912:09
anubhavcan you try a plugging your device to a different port?12:10
kjdrowell only if i interupt the copy proces.. witch understandably is not what i want to do.. only if there would be a way to restart the copy where it left of.. skiiping the already copied files12:12
kjdrois there ?12:12
anubhavi think cp -u12:13
kjdrohmmm ...12:13
anubhavu can just check the man page12:13
kjdrocopy only when the SOURCE file is newer than the destination file or when the destination file is missing12:14
kjdroyour right..12:14
kjdronow how do i copy multi structured paths... anyway .. give me a min to ready man cp12:14
kjdro-r ...12:15
kjdrook12:15
anubhavdo you copy using the gui?12:16
kjdrohmm final thought... will a sistem boot up if i copy all the files it needs using cp .. with dircetory structure to the root partition ?12:16
kjdroi am usiong mc's copy12:16
kjdromidnight commander12:16
anubhavwith cp you have to be carefull that it copies all symbolic links etc12:18
kjdroaha... so best would be if i untar the file system directly... shiut...12:19

lesshastehow do I get alt-sysrq to work in ubuntu?21:00
doctormoI'm looking for advice, I have a serial device I'm going to try and reverse engineer. It's a USB <-> Serial chip which produces a /dev/ttyUSB0 as expected.22:52
doctormoGiven that the windows program works in wine, should it be easy to watch the io of wine to sniff out the protocol?22:52
JanCis there any extra protocol involved?22:56
doctormoJanC: Yes, the one that sends the images to be displayed on the device via serial.23:06
doctormoI'm trying to find a guide on logging a processes io, but not having much luck23:06
JanCah, so there is more than the usb <-> serial chip23:07
doctormoJanC: Yes, the ttyUSB0 is sym linked to wine's com123:08
JanCi guess there must be something that experienced reverse engineers use  ツ23:08
doctormodid you just use the katakana Shi as a smilie face?23:08
JanCyep23:09
doctormoare you Japanese?23:09
JanCno, its use as a smiley probably started inside ubuntu-nl (although I'm not sure about that)23:10
doctormoheh, oh well23:11
doctormoBack to logging serial io... still no results in google. keep trying23:14
JanCthe "easiest" way would be to have a fake serial device that logs everything and sits between the app & the real hardware driver23:17
JanCor maybe the driver that creates the ttyusb devices can already do that?23:18
johanbrdoctormo: There's something called usbsnoop for windows. It might work under wine.23:18
JanCjohanbr: as the app under wine accesses it as com1, that probably won't work?23:19
JanC(wine doesn't know this is an USB device)23:20
JanCdoctormo: http://linux.die.net/man/1/slsnif sounds useful23:22
JanCdoctormo: and http://www.suspectclass.com/~sgifford/interceptty/23:23
doctormothanks23:42
