I'm trying to set up a usb-uirt (http://www.usbuirt.com) on my up-to-date F8 box with a 2.6.23.9-85.fc8 kernel and lirc-0.8.2-2.fc8 I'm installing MythTV on. When I start lircd I see no errors, but when I run irw, I see [root@janus ~]# lircd -n -d /dev/ttyUSB0 --driver=usb_uirt_raw lircd-0.8.2[10913]: lircd(userspace) ready lircd-0.8.2[10913]: accepted new client on /dev/lircd lircd-0.8.2[10913]: uirt2_raw: checksum error lircd-0.8.2[10913]: uirt2_raw: UIRT version 0905 ok lircd-0.8.2[10913]: uirt2_raw: could not set DTR lircd-0.8.2[10913]: caught signal Poking around, this sounds like an old bug somewhere upstream (kernel): http://www.gossamer-threads.com/lists/mythtv/users/293503 Is there any way to track down this problem? Is it really broken from back to the 2.6.22 kernels? Anything I can do about it? Thanks.
