I have tried value of 1 - still get dups. Duplicated data occurs rarer, but a larger chunks of it get duplicated. I attach test data - typescript of `at&v' command and corresponding usbmon data. File name notation: *-n1 data with ACM_NRU=ACM_NRB=1 *-n16 data with ACM_NRU=ACM_NRB=16 *-old data with 2.6.15 cdc_acm driver. In the `n1' case the second attempt of at&v results in a duplicated line. `n16' produces lots of small dups. `old' produces no dups. -- Alexander.
