DR-891 - no COM port?

Hi, new to digirig and received my dr-891 at the weekend. I’ve been having trouble getting it set up. I’m connecting it using a Digirig cable (the curly one, got it from amazon)

The audio devices appear and I can set them up as suggested but nothing appears for the silicon labs bridge (I don’t even get a Ports section in device manager).

I have tried the driver install anyway and have rebooted everything a few times and tried different USB ports with no luck. I have run the device trouble shooter and windows update as well and that didn’t help.

I’m usually a mac person and my Mac has usb-c so I thought I’d try with that, and with a completely different cable. I did the “ls /dev/tty.*” and only had two entries for bluetooth things. After plugging the dr-891 in I waited a while and ran it again but nothing new was added. I did see a new device appear in the sound part of the settings though and that disappears when I unplug the dr-891.

I’m at a bit of a loss what to try next. All suggestions gratefully received. I have screenshots of a lot of this but didn’t want to bloat the thread, can post on request.

thanks

Just to add, I’ve not plugged anything else into the dr-891 yet. Just the usb from the computer , not connected to the radio at all, in case that makes a difference. This is as per the instructions but they’re for the regular model.

John,
The COM port will appear when you connect your radio.
With DR-891 the interface doesn’t have its own serial port, but allows a USB pass through to the USB-to-serial bridge inside of FT-891.

Aha! Thanks…Ok… Will try now

Maybe worth adding that to the manual? Would have saved me 3hrs messing around :⁠-⁠)

Yes, DR-891 is a recent addition to the lineup and the support materials will have to improve. There are tutorial videos that are now starting to pop up on youtube, that make things a bit easier for the operators.

I am having a similar issue with my DR891. I ordered it a few months ago and it was on backorder, and received it. Finally got around to trying it with my FT-891. I am not showing any ports and am showing "Unknown USB device (Port reset failed) in my USB controllers. I have a couple of the standard digirigs as well and they work great. Any ideas?

Do you see COM port on your computer when you connect radio’s USB directly to computer without Digirig being involved?

I figured it out! I ended up having to download drivers and now I see the comm ports like I do on my other computer!

Just to report back, plugging into the radio meant I got the com ports! I’ve had my first qsos :⁠-⁠)
