I'm also seeing the regression reported by @richard (#42). In particular, the software for the Syscomp CGR-101 isn't seeing the scope on a 64 bit Ubuntu Maverick 10.10. Building the latest version of the ftdio_sio driver from the 2.6.35-8 linux tree didn't fix the bug, but porting the version @tz (#7) found to the new kernel fixed the issue. I've attached the ported version of the older driver for those who need a fix now. The install instructions are the same as before: To install: 1) open a terminal window 2) install the latest kernel headers: # sudo apt-get install linux-headers-generic 3) download and uncompress the attached file ftdifix.backport.maverick.tar.gz 4) change to the directory where you uncompressed the file, e.g. # cd ftdifix.backport.maverick 5) build the driver: # make 6) install the driver # sudo make install Until this is fixed, you may have to repeat these steps each time you install a new version of the kernel. This isn't a good long-term fix, however - there have been a lot of changes to the driver, many of which add support for new devices. The right fix is probably to do a bisection on the kernel checkins to find the one that broke this driver for this scenario, and then report the bug upstream (ideally with a patch). I'll start the process but I'm not sure how much time I'll be able to devote to it - if some else wants to give this a try, feel free. ** Attachment added: "port of ftdi driver from linux kernel 2.6.31.8" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/460857/+attachment/1725253/+files/ftdifix.backport.maverick.tar.gz -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

tz's makefile worked like a charm. For those who don't want to download the linux kernel sources for two files, here are the two files and a modified version of tz's makefile (with a 'make install' option added). To install: 1) open a terminal window 2) install the latest kernel headers: # sudo apt-get install kernel-headers-generic 3) download and uncompress the attached file ftdifix.tar.gz 4) change to the directory where you uncompressed the file, e.g. # cd ftdifix 5) build the driver: # make 6) install the driver # sudo make install Until this is fixed, you may have to repeat these steps each time you install a new version of the kernel. ** Attachment added: "ftdifix.tar.gz" http://launchpadlibrarian.net/36889614/ftdifix.tar.gz -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It appears that anyone can change the status of a bug (including us). Kalda and Peter both have 0 lauchpad karma - Peter has posted two bug comments in the past two years and Kalda's account was created today. Neither one includes a public email address, so we can't contact them directly. Thus I'm concerned that they may not be people in an appropriate position to mark bugs as incomplete. Kalda and Peter, if you're active contributors to the project, could you let us know what information is missing? All of us would like to help strengthen the project, and are willing to help if you let us know what is needed. If we don't hear back from Kalda and Peter in the next couple of days, I suggest we change the status back to "new" to make sure this bug stays on the radar. -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It sounds like both of the status changes from new to incomplete were unintentional, so I've changed the status back to new. ** Changed in: linux Status: Incomplete => New ** Changed in: linux (Ubuntu) Status: Incomplete => New -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@David (#16) Good catch - that should be "sudo apt-get install linux-headers-generic" (I shouldn't have typed it from memory). Hopefully this will get the patch to work for you. If you see an error during the first "make", however, there are still problems - please post the error and we'll see if we can help. I'm using this on 64-bit Karmic, and have just verified that I'm able to "cat /dev/ttyUSB0" and see serial data sent from an Arduino. -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 460857] Re: ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48)
@David (#30) Unfortunately it looks like the drivers on the ftdi site may not work with newer versions of the kernel, including the kernel in karmic. The ftdi_sio.h and .c I grabbed were from the linux kernel tree (version 2.6.31.8). A number of changes seem to have been made without increasing the version number - lots of reformatting and rearrangement (which makes it hard to diff), but also a much longer list of supported device ids. Running the modified version of tz's makefile with the ftdi version also gives a list of errors which look like the result of changes to the usb structure in newer kernels (references to the fields tty and open_count that aren't in the usb_serial_port structure in the kernel headers). I'm not an expert in kernel drivers, however, so there may be an easy way to update this driver that I'm missing. To be honest, I'm worried that you're grappling with an additional bug (e.g. a bug in the driver for your usb chipset) in addition to the FTDI bug the rest of us had. It sounds like the symptoms you are encountering are somewhat different than what the rest of us had, and the fix that worked for the rest of us (tz's) isn't working for you. I've been hesitant to suggest this, however, because I don't have a good suggestion of how to fix this new bug. Doing a search on "khubd karmic" turns up a lot of bugs with similar symptoms, many of which are unresolved. It's not clear to me which (if any) match the problem you're encountering, however; this looks like it may just be a common mode of failure. It may be worth doing some additional searches based on your laptop model and usb chipset to see if any existing bug seems to match what you're seeing. If not, it may be worth opening a new bug. -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 468243] [NEW] [Thinkpad X61 tablet] suspend/resume failure
Public bug reported: The machine during suspend from the desktop every (4/4) time I tried, hybernate from desktop hung 1/1 time tried, but I had no problems . Suspend worked fine when I tried it (once) from the (graphical) login screen. While suspend from the desktop hasn't worked yet on my machine, my room mate (with a very similar computer) has had no problems. Perhaps this is an obsolete driver or driver setting?
