[Bug 18689] New: Wine serial-handling consumes 100% CPU when using USB->Serial-converter
http://bugs.winehq.org/show_bug.cgi?id=18689
Summary: Wine serial-handling consumes 100% CPU when using USB->Serial-converter Product: Wine Version: 1.1.22 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: ntdll AssignedTo: wine-bugs@winehq.org ReportedBy: henjac@gmail.com
Created an attachment (id=21403) --> (http://bugs.winehq.org/attachment.cgi?id=21403) Patch from december 2008 solving the bug
Ubuntu 9.04 Wine 1.1.22 SeaClear II v1.0.0.196 USB-GPS: GlobalSat BU-353 USB (pl-2303-driver in linuxkernel)
Symptoms: When running the above combo Wine consumes 100% of available CPU. If I start without GPS everything is as is should (no obsessive cyclestealing) The app works in both scenarios but obviously something is not quite right in how Wine handles the USB-Serial-converter. (This behavior is also verified in VectorLinux 6.0)
I found a patch for it: http://www.nabble.com/serial-04-04%3A-fix%3A-WaitCommEvent()-does-not-work-a...
The above patch solves my problem. However, the latest version of Wine I managed to apply the patch to is 1.1.17.
Could a developer take a look at the patch and if possible integrate it into the Wine-sourcetree.

It is still an issue. I have the same problem. My setup below:
Ubuntu 9.10 Wine 1.1.40 SeaClear II v1.0.0.205 USB-GPS: GlobalSat BU-353 USB (pl-2303-driver in linuxkernel)

--- Comment #5 from Alec Leamas leamas.alec@gmail.com 2010-07-22 12:48:25 --- Seems like this bug is about all serial handling, not only serial-USB converters.
I have tested a bluetooth connection to the GPS i. e., using /dev/rfcomm* for IO. The symptomes are the same, 100% CPU load. The SeaClear II program is using the serial IO from Windows. Fedora 13, wine 1.1.38
The bug can also be reproduced using /dev/pts pseudo terminals, without any hardware involved. See http://appdb.winehq.org/commentview.php?iAppId=3659&iVersionId=5417&... (although there certainly are other, less clumsy ways to reproduce the bug).

Development recommends to check the status on your bug every release or two and let to be known if the bug is still present. If not, mark it fixed. If you are no longer able to put effort to this ticket, you can abandon it.
Is this still an issue with 1.7.7 or higher ?

--- Comment #9 from Bruno Jesus 00cpxxx@gmail.com --- Fixed somewhere between 1.6 and 1.7.30, I suspect it was fixed by Dmitry between September and October 2013. Tested with real hardware. I can see the cpu burning in 1.6 and everything fine in 1.7.30.
