Hello,

Here is the entry for the device with the 0xEEEF product ID:
Code: [Select]
<key>microHAM USB Port</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
<key>IOClass</key>
<string>FTDIUSBSerialDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>0</integer>
<key>idProduct</key>
<integer>61167</integer>
<key>idVendor</key>
<integer>1027</integer>
</dict>

And for reference here is a standard FT232R device:
Code: [Select]
<key>FTDI R Chip</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
<key>IOClass</key>
<string>FTDIUSBSerialDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>0</integer>
<key>bcdDevice</key>
<integer>1536</integer>
<key>idProduct</key>
<integer>24577</integer>
<key>idVendor</key>
<integer>1027</integer>
</dict>

The Microham device hasn't defined any special settings for latency timer, buffer sizes of buad rate aliasing, which is where my original comment stems from. However the have omitted the bcdDevice field which may cause issues depending on which IC they are using. If they are advising their software wont work when the FTDI defaults are used then I would stick with this advice. But in general as a stop gap solution it is perfectly fine to re-program a device to use FTDI defaults.

Best Regards,

Thanks for the information. I changed the PID of the microHAM USB Interface III to 0x6001 (24577) and it works now with the standard macOS Big Sur .dext

Related to this, it seems that there's some problem with the kext driver version 2.4.4 notarization, so the installer refuses to start even on macOS 10.15.

Any update on VCP drivers for Big Sur? I'm hearing daily from upset customers that their device does not work.. and Big Sur has been out for months now.... :(

Hello,

Unfortunately there hasn't been any updates from our driver team as of yet, but I will be sure to post any updates when I receive them.

It's been more than another month now... it seems clear that nobody is actually working on this. The new driver requirements are not *that* horrible - they are no longer .kext, but Apple is pretty transparent about how you need to set them up and sign them etc.

Any chance we'll get new drivers from FTDI this quarter?

03/19/2021 Update: No. No chance they'll get this out this quarter. Maybe this summer.

This is getting really pretty old.  When is this problem going to get any attention?

Thanks for verifying that it's possible to get a Microham device working with Big Sur's native driver.  What exactly did you have to do to get it working?  Presumably just editing some text configuration file, but which/how?

I changed the PID with FTDI's FT_Prog software on a Windows computer. It's a pretty easy exercise.

I was reminded of this problem by one of my customers. can someone give the developers some strong coffee? and make it a very big red point on the top of their list? this is becoming very embarrassing.

Hello,

I have be liaising with the driver team recently and they are making good progress. We are currently establishing which features supported in our driver but not in the Apple driver are most pertinent for a beta release. For example, baud rate aliasing or latency timer settings.

If you are using any of these feature please let me know.

Best Regards,
FTDI community.

On macOS 10.15 we had noticed that a Wacom Tablet driver was preventing both our VCP driver and apples VCP driver from attaching to devices and providing a COM port in the '/dev' folder. This may still be the case for some of your customers on Big Sur, however it could be an issue with the Apple driver itself.

I just registered an account on this forum to confirm that uninstalling Wacom resolved my connection issues.
I was fighting this problem for several days before I found this solution. I hope that my confirmation saves someone else some time.

Wacom drivers are the worst...
