I tried unloading and reloading the module afterward and I still do not seem to get the serial device back. I need to pull the cable or issue a USBDEVFS_RESET IOCTL call to the the hub that the FT232R is connected to (issuing the IOCTL to the FT232R isn't enough). I also read that the internal EEPROM must match what I tell ftdi_set_bitmode() call, which is a drag. Offhand, how do you control CBUS4? There aren't enough bits in the bitmode call to control it. -A. -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
