o option, but a generic solution might be better. I obviously don't know, but would be very happy to supply further information! thanks, ben -- Ben Adler Universität Hamburg MIN-Fakultät FB Informatik, AB TAMS Vogt-Kölln-Strasse 30 22527 Hamburg Tel +49 40 42883 2504 Fax +49 40 42883 2397

Re: Serial ports for Septentrio USB GNSS receiver

and sometimes (not always) I see latencies similar to this (in milliseconds): 34 6 44 5 51 8 20 7 So I could also imagine that there is a buffer (probably of 61bytes) that only gets flushed once its full. Is there, by any chance, a 64 byte buffer in the cdc_acm module or linux USB code

ints is bulk, not interrupt, but maybe there's a few tricks to make bulk-transfers faster? Right now I'm seeing latencies between 5 and 70ms. thanks! ben -- Ben Adler Universität Hamburg MIN-Fakultät FB Informatik, AB TAMS Vogt-Kölln-Strasse 30 22527 Hamburg Tel +49 40 42883 2504 Fa
