Looks like it registered just fine. Try creating the device nodes manually? The difference in /proc/tty/driver/serial is because ARM doesn't have legacy X86 serial ports in fixed in IO-space (ie: com0-3 on PC) Clarified some things on IRC, I'm going to try to reproduce this tomorrow on my rev A2 with pl2303. Did magic happen here? Josh, not sure what you're aiming at, but to my knowledge things haven't changed. Kyle, did you get a chance to look at this yet? No, we dropped pandaboard as a "supported" platform in F-20 and I've been busy with other things. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.12.6-200.fc19. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 20, and are still experiencing this issue, please change the version to Fedora 20. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug has been in a needinfo state for more than 1 month and is being closed with insufficient data due to inactivity. If this is still an issue with Fedora 19, please feel free to reopen the bug and provide the additional information requested. |
