| wgrant | Is 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 |

| kjdro | using ext3 Tryed first on ubuntu 8.04 and was slow.. and some forums i'w read that ubuntu 8.10 solved the issu.. so i downed 8.10 and used live cd ... whit boot option pci=routeirq .... still nothing... | 11:01 |
| anubhav | kjdro:it works okay with windows? | 11:01 |
| kjdro | sadly yes | 11:01 |
| kjdro | but ... i cant untar to ext3 there... | 11:02 |
| anubhav | kjdro:why not untar it onto a FAT partition and then copy | 11:04 |
| anubhav | kjdro:also file a bug with all the required info | 11:04 |
| kjdro | well i need the debian base station on stick to boot up my debian-slug.. so i need ext3 file sistem... | 11:04 |
| kjdro | and well.. i tryed both aproaches.. untar in on hdd witch takes a few seconds | 11:05 |
| anubhav | kjdro:have you filed a bug report? | 11:06 |
| kjdro | then there is a bug files.. it always has been ... google it.. :D there are dosns.. | 11:06 |

| kjdro | looking for a solution to speed up usb transfer without restarting | 11:09 |
| anubhav | kjdro:whats the output of hwinfo --usb | 11:10 |
| kjdro | well this: > block.5: /dev/sdc .. and it hangs after | 11:11 |
| kjdro | hold on.. i see some movement | 11:12 |
| kjdro | ok.. so this may take a while | 11:13 |
| kjdro | > block.5.1: /dev/sdc geo | 11:13 |
| kjdro | i'm still copying some info on the stick.. really dont want to interupt... what is strange... is ... i tryed untaring .. and each time i start up again and mount usb drive.. it looks empty... like nothing has been copyed on it | 11:14 |
| kjdro | > block.5.2: /dev/sdc serial | 11:21 |
| kjdro | ok so i gess .. this is a *bump* again.... yo alex_joni: che faci... | 11:24 |
| kjdro | alex_joni: esti ? | 11:24 |
| kjdro | nvm | 11:25 |
| kjdro | anubhav: are you there? take a look at this: | 11:58 |
| kjdro | http://paste.ubuntu.com/128179/ | 11:58 |
| kjdro | this is the otuput.... | 11:58 |
| anubhav | kjdro:okay | 11:58 |
| kjdro | everithing seems alright ? | 12:00 |
| kjdro | to me at least it dose | 12:01 |
| anubhav | kjdro:can you start a thread on ubuntuforums and provide the output of dmesg,lspci -vvn ? | 12:02 |
| kjdro | of course | 12:02 |
| anubhav | okay once you do that send me the link of the thread | 12:03 |
| kjdro | http://paste.ubuntu.com/128181/ | 12:04 |
| kjdro | this is lspci | 12:04 |
| kjdro | yeah well | 12:05 |
| kjdro | in dmesg you could see a lot of: usb 8-1: reset high speed USB device using ehci_hcd and address 4 | 12:05 |
| kjdro | what specificly interest you so i use grep ... | 12:06 |
| kjdro | or if you want all i could redirect output to a file | 12:06 |
| kjdro | witch is it ? | 12:07 |
| anubhav | u can try dmesg|tail | 12:07 |
| anubhav | okay complete dmesg will be better | 12:07 |
| kjdro | yeah well: | 12:07 |
| kjdro | dmesg | tail | 12:08 |

| kjdro | as i sad... :( | 12:08 |
| kjdro | some 2 pages of that ore more in the full output of dmesg | 12:08 |
| kjdro | well .. about the forum.. i read now.. well... kinda lack the time... right now.. | 12:09 |
| kjdro | my copy is at 41%.... since 9:00 am this moring .. now it's 14:09 | 12:09 |
| anubhav | can you try a plugging your device to a different port? | 12:10 |
| kjdro | well 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 files | 12:12 |
| kjdro | is there ? | 12:12 |
| anubhav | i think cp -u | 12:13 |
| kjdro | hmmm ... | 12:13 |
| anubhav | u can just check the man page | 12:13 |
| kjdro | copy only when the SOURCE file is newer than the destination file or when the destination file is missing | 12:14 |
| kjdro | your right.. | 12:14 |
| kjdro | now how do i copy multi structured paths... anyway .. give me a min to ready man cp | 12:14 |
| kjdro | -r ... | 12:15 |
| kjdro | ok | 12:15 |
| anubhav | do you copy using the gui? | 12:16 |
| kjdro | hmm 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 |
| kjdro | i am usiong mc's copy | 12:16 |
| kjdro | midnight commander | 12:16 |
| anubhav | with cp you have to be carefull that it copies all symbolic links etc | 12:18 |
| kjdro | aha... so best would be if i untar the file system directly... shiut... | 12:19 |
| anubhav | yeah | 12:20 |

| lesshaste | how do I get alt-sysrq to work in ubuntu? | 21:00 |
| doctormo | I'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 |
| doctormo | Given that the windows program works in wine, should it be easy to watch the io of wine to sniff out the protocol? | 22:52 |
| JanC | is there any extra protocol involved? | 22:56 |
| doctormo | JanC: Yes, the one that sends the images to be displayed on the device via serial. | 23:06 |
| doctormo | I'm trying to find a guide on logging a processes io, but not having much luck | 23:06 |
| JanC | ah, so there is more than the usb <-> serial chip | 23:07 |
| doctormo | JanC: Yes, the ttyUSB0 is sym linked to wine's com1 | 23:08 |
| JanC | i guess there must be something that experienced reverse engineers use ツ | 23:08 |
| doctormo | did you just use the katakana Shi as a smilie face? | 23:08 |
| JanC | yep | 23:09 |
| doctormo | are you Japanese? | 23:09 |
| JanC | no, its use as a smiley probably started inside ubuntu-nl (although I'm not sure about that) | 23:10 |
| doctormo | heh, oh well | 23:11 |
| doctormo | Back to logging serial io... still no results in google. keep trying | 23:14 |
| JanC | the "easiest" way would be to have a fake serial device that logs everything and sits between the app & the real hardware driver | 23:17 |
| JanC | or maybe the driver that creates the ttyusb devices can already do that? | 23:18 |
| johanbr | doctormo: There's something called usbsnoop for windows. It might work under wine. | 23:18 |
| JanC | johanbr: 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 |
| JanC | doctormo: http://linux.die.net/man/1/slsnif sounds useful | 23:22 |
| JanC | doctormo: and http://www.suspectclass.com/~sgifford/interceptty/ | 23:23 |
| doctormo | thanks | 23:42 |
