-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list users, I've been experiencing very strange errors for the last week with usbserial/PL2303 driver. Everything used to magically work until a week ago. syslog output is attached. Eventually used stty parameters are attached. Distribution is Slackware64-13.1 (64bit) I've tested kernels 2.6.32.25, 2.6.32.28 and 2.6.32.31 and it does happen in all of them. - ---- # uname -a Linux osiris 2.6.32.31-v4l #3 SMP Fri Mar 4 06:55:55 CET 2011 x86_64 Intel(R) Celeron(R) CPU E3200 @ 2.40GHz GenuineIntel GNU/Linux - --- I don't say it's faulty driver. No! But I do seek some "consultancy" what the heck is going wrong :( If any more info is needed, please, let me know. Thank you for any suggestions.
