Hi, Having an UST2009 dual serial port and try to use it I ran into an unexpected effect. Attached is a part of /var/log/debug it starts at 09:30 when I inserted "usbserial" and "mos7720" both with debug enabled. in the attached debug-log file the driver does overrides for functions that the mos7720 driver clearly provides. as such status = ioctl(hartfd.fd, TIOCMGET, &parm); on /dev/ttyUSB0 returns error 22. Why does it do the overrides? From the debug log I can see doe it never reaches the ioctl in the mos7720 driver. kind regards Kees PS: Linux version 2.6.30 (root@xxxxxxxxxxxxxxxxxxxxxxxxxxx) (gcc version 4.3.3 (Debian 4.3.3-3) ) #1 SMP PREEMPT Mon Jun 22 11:07:33 CEST 2009 -------------------------------------------------------
