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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
