HCF (controllerless) driver

This package contains Linux drivers for the Conexant HCF (controllerless) modem family.

The drivers should work on most current Linux distributions, with the 2.4 or 2.6 kernels. Some systems may require kernel recompilation with special ACPI patches.

It will not work on x86_64 (amd64) unless you use a 32-bit Linux distribution.

Apple Power Macintosh (PPC) systems require at least kernel 2.4.20.

The following PCI modem devices are recognized by the hcfpcimodem driver:

  • PCI ID {127A,14F1}:{1002,1003,1004,1005,1006} (71DP v90)

  • PCI ID {127A,14F1}:{1025,1085,2005} (if it doesn't work, try HSF driver)
  • PCI ID {127A,14F1}:{2004,2006}
  • PCI ID {127A,14F1}:{1032,1033,1034,1035,1036}

  • The following USB modem devices are recognized by the hcfusbmodem driver:

  • USB Vendor ID: 0572 Product ID: 1290 (Cadmus2 HCF, Conexant)
  • USB Vendor ID: 05AC Product ID: 8202 (Cadmus2 HCF, Apple)
  • Many vendors (such as Dell, Compaq/HP, IBM, U.S. Robotics/3Com, etc..) have shipped modems based on Conexant modem chipsets. If you have a modem based on the HCF chipset but with non-standard vendor or device IDs, please contact If supported, your device could be added to the list and automatically recognized in future versions of this driver.

    See the INSTALL file for installation instructions.

    The modem AT command set is described in the file 100498D_RM_HxF_Released.pdf.

    Bug reports are welcome. (see section "REPORTING PROBLEMS" in INSTALL file)
