These interfaces use the FTDI chipset with different Vendor and Product IDs. I also addd two additional baud rate enumerations. The vehicle bus interfaces use a baud rate of 2000000. I also added 3000000 since it is the other FTDI baud divisor special case. A better fix would be to calculate the divisors on the fly for any arbitrary baud rate (+ the two 2M and 3M special cases). >How-To-Repeat: >Fix: --- usbdevs.orig Thu May 20 19:36:48 2004 +++ usbdevs Sat May 29 14:42:55 2004 @@ -316,6 +316,7 @@ vendor BIOMETRIC 0x0929 American Biometric Company vendor TOSHIBA 0x0930 Toshiba Corporation vendor PLEXTOR 0x093b Plextor Corp. +vendor INTREPIDCS 0x093c Intrepid Control Systems vendor YANO 0x094f Yano vendor KINGSTON 0x0951 Kingston Technology vendor BLUEWATER 0x0956 BlueWater Systems @@ -793,6 +794,10 @@ /* Intersil products */ product INTERSIL PRISM_2X 0x3642 Prism2.x or Atmel WLAN + +/* Interpid Control Systems products */ +product INTREPIDCS VALUECAN 0x0601 ValueCAN CAN bus interface +product INTREPIDCS NEOVI 0x0701 NeoVI Blue vehicle bus interface /* I/O DATA products */ product IODATA USBETT 0x0901 USB ETT --- uftdi.c.orig Wed Mar 17 18:02:46 2004 +++ uftdi.c Sat May 29 14:44:21 2004 @@ -164,6 +164,15 @@ uaa->product == USB_PRODUCT_FTDI_LK204)) return (UMATCH_VENDOR_PRODUCT); + /* + * The Intrepid Control Systems' ValueCAN and NeoVI vehicle + * bus interfaces use the FTDI interface. + */ + if (uaa->vendor == USB_VENDOR_INTREPIDCS && + (uaa->product == USB_PRODUCT_INTREPIDCS_VALUECAN || + uaa->product == USB_PRODUCT_INTREPIDCS_NEOVI)) + return (UMATCH_VENDOR_PRODUCT); + return (UMATCH_NONE); } @@ -223,6 +232,8 @@ case USB_PRODUCT_FTDI_MX4_5: case USB_PRODUCT_FTDI_LK202: case USB_PRODUCT_FTDI_LK204: + case USB_PRODUCT_INTREPIDCS_VALUECAN: + case USB_PRODUCT_INTREPIDCS_NEOVI: sc->sc_type = UFTDI_TYPE_8U232AM; sc->sc_hdrlen = 0; break; @@ -499,6 +510,8 @@ case 230400: rate = ftdi_8u232am_b230400; break; case 460800: rate = ftdi_8u232am_b460800; break; case 921600: rate = ftdi_8u232am_b921600; break; + case 2000000: rate = ftdi_8u232am_b2000000; break; + case 3000000: rate = ftdi_8u232am_b3000000; break; default: return (EINVAL); } --- uftdireg.h.orig Sat May 29 09:55:02 2004 +++ uftdireg.h Sat May 29 09:56:20 2004 @@ -104,7 +104,9 @@ ftdi_8u232am_b115200 = 0x001a, ftdi_8u232am_b230400 = 0x000d, ftdi_8u232am_b460800 = 0x4006, - ftdi_8u232am_b921600 = 0x8003 + ftdi_8u232am_b921600 = 0x8003, + ftdi_8u232am_b2000000 = 0x0001, /* special case for 2M baud */ + ftdi_8u232am_b3000000 = 0x0000 /* special case for 3M baud */ }; /* >Release-Note: >Audit-Trail: >Unformatted:
