3 | RTSystems usb cables are a branded (i.e., customized) FTDI cable. They simply have different USB Vendor (VID) and Product IDs (PID) from generic FTDI USB adapters. |
||
4 | |||
5 | Apple OSX 10.9.x aka Mavericks now has a built in FTDI Driver, com.apple.driver.AppleUSBFTDI. |
||
6 | However, it does not load by default because it does not recognized the custom VID/PID combos that RTSystems cables use. |
||
7 | |||
8 | 2 | Jens Jensen | Many folks have been simply loading the FTDI OEM driver, com.FTDI.driver.FTDIUSBSerialDriver (2.2.18), and this works, but I have been able to reproduce a nasty hang when uploading from chirp to some Yaesu radios, e.g., VX-6. |
9 | |||
10 | The workaround is to disable the OEM driver, and modify and load the Apple FTDI driver. |
||

12 | Warning you take all responsibility for mucking with your system files. Know what you are doing and how to undo it before you proceed. We do not take any responsibility for issues arising from this. |
||
13 | |||
14 | Also, if you do not have any issues with your RTSystems FTDI cables, Chirp, Mavericks, and the FTDI OEM driver, then don't bother with this procedure. |
||
15 | |||
16 | This is a workaround only for people who have been having these issues. |

||
20 | |||
21 | 4 | Jens Jensen | * stop using and unplug all FTDI usb adapters |
22 | 1 | Jens Jensen | |
23 | 4 | Jens Jensen | * unload existing FTDI OEM driver (if applicable): |
24 | 5 | Jens Jensen | @ |
25 | 1 | Jens Jensen | sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver |
26 | 5 | Jens Jensen | @ |
27 | 1 | Jens Jensen | |
28 | 4 | Jens Jensen | * Disable FTDI OEM driver (if applicable): |
29 | 1 | Jens Jensen | @ |
30 | sudo mv -v /System/Library/Extensions/FTDIUSBSerialDriver.kext/ /System/Library/Extensions/FTDIUSBSerialDriver.kext_disabled |
||
31 | @ |
||
32 | |||
33 | 4 | Jens Jensen | * check to see that there are no FTDI drivers loaded: |
34 | 1 | Jens Jensen | @ |
35 | kextstat |grep -i ftdi |
||
36 | @ |
||
37 | (should not show anything) |
||
38 | |||
39 | 4 | Jens Jensen | * Add RTSystems VID/PIDs to Apple FTDI driver: |
40 | 1 | Jens Jensen | @ |
41 | sudo nano /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBFTDI.kext/Contents/Info.plist |
||
42 | @ |

72 | |||
73 | 4 | Jens Jensen | * plug in your rtsystems ftdi usb adapter |
74 | 1 | Jens Jensen | |
75 | 4 | Jens Jensen | * Force load of Apple FTDI driver: |
76 | 1 | Jens Jensen | @ |
77 | sudo kextload -b com.apple.driver.AppleUSBFTDI |
||
78 | @ |
||
79 | |||
80 | 4 | Jens Jensen | * verify Apple FTDI driver is loaded: |
81 | 1 | Jens Jensen | @ |
82 | 10 | Jens Jensen | kextstat |grep -i ftdi |
83 | 1 | Jens Jensen | 129 0 0xffffff7f826d0000 0x7000 0x7000 com.apple.driver.AppleUSBFTDI (1.0.1b3) <77 36 5 4 3> |
84 | 10 | Jens Jensen | $ |
85 | 1 | Jens Jensen | @ |
86 | |||
87 | 4 | Jens Jensen | * Verify Apple FTDI device node is created: |
88 | 1 | Jens Jensen | @ |
89 | ls -l /dev/cu.usbserial-* |
||
90 | @ |
||
91 | |||
92 | 9 | Jens Jensen | *good result*: should list a device file |
93 | *bad result*: "no such file or directory" |
||
94 | 1 | Jens Jensen | |
95 | 3 | Jens Jensen | *you should now be able to use your adapter* |
96 | 1 | Jens Jensen | |
