Upstream requested changes and the original author never followed up as far as I can tell. We can't apply this as-is. Moving this bug to rawhide as it needs to be fixed there first if we get to it. Maybe duplicate of #1235715 This bug still exists with kernels 4.7.3.200-fc24.x86_64 and 4.7.4.200-fc24.x86_64 This has not been fixed with the Fedora 25 Beta 1 release. Kernel 4.8.0-0.rc7.git0.1.fc25.x86_64 USB-Serial Adapter driver: ch341 idVendor=1a86, idProduct=7523 The chipset is recognized, and the ch341 kernel module is loaded, but the baud rate is not set correctly, and so garbage is sent/received through the usb/serial adapter instead of valid characters (for instance with minicom). Fixed. Thanks. See: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1235715 |
