Subject: [PATCH] pl2303 works at 500kbps
Date: Tue, 21 May 2013 13:31:31 +0200 [thread overview]
Message-ID: <519B5B13.1020807@ventoso.org> (raw)
My PL2303HX works at 500kbps after applying this patch.
I suppose that it could work at other non standard speeds since this fix
"correctly handle baudrates above 115200"
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/serial/pl2303.c?id=8d48fdf689fed2c73c493e5146d1463689246442
came after this one
"fix baud rate handling in case of unsupported values"
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/serial/pl2303.c?id=25b8286805e856c8c7fda127018e31032c918015
but I only can test it with 500000.
Patch made against mainline but tested with 3.4.45
Please CC me since I'm not subscribed
