Hi, these calculations done in ftdi_2232h_baud_base_to_divisor look suspicious to me: /* hi-speed baud rate is 10-bit sampling instead of 16-bit */ divisor3 = (base / 10 / baud) * 8; divisor = divisor3 >> 3; divisor |= (__u32)divfrac[divisor3 & 0x7] << 14; Is it supposed to always use divfrac[0] (== 0)? If not, I'd write divisor3 = base * 8 / (baud * 10); instead. Daniel -- Dipl.-Math.
