Hi,
A few days ago I created a bug report
(https://bugzilla.kernel.org/show_bug.cgi?id=16094) about a problem
with the CP210x driver in the linux kernel.
As suggested by Greg Kroah-Hartman, I'm forwarding the list the
kernel log messages and lsusb output.
The problem is that a fopen() to /dev/ttyUSB0 fails most of the
times with older kernels (2.6.26) and all the time with newer kernels
(2.6.33.3). I found that a simple test is stty -F /dev/ttyUSB0. This
fails with "Protocol error".
Opening the port with minicom also triggers the same issue.
I began to compare the cp210x with the ftdi_so and I found that
they use very different values for the usb_control_msg() call. The
first uses 300 while the later uses 5000. The original driver from
Silabs (available at their website) also uses 300. I changed it to
5000 (see patch below) and it seems to fix the problem for me. But
since I'm no kernel hacker, I'm not so sure if this is a proper fix or
not.
I'm not on the list, please keep me in the cc.
Kind Regards,
Thiago A. Correa
