Hello everybody,
I've actually some problem when trying to read data from a u-blox LEA-6T
USB module. My kernel is the 2.6.34 and I'm using the cdc_acm driver to
read data from the GPS.
The GPS is sending a packet every second, but when I try a "hexdump
/dev/ttyACM0", <file:///dev/ttyACM0%22%2C> I do only receive some data
every 5, 10 or even 20 seconds instead of every second as if it has been
buffering the data. But I am receiving the correct number of packets
(for example 10 every 10 seconds, 5 every 5, etc.). I'm also losing some
data (a few bytes) when I receive the data.
I've checked with a few kernels and linux distros, and I haven't been
able to find some coherency.
Does someone has an idea where to search ? Thanks
Best regards,
Jérôme
