Reach can't find 3DR radio connected via USB OTG

I have the 3dr radio connected via usb otg and it powers on but does not show up as an option in reachview.
I am trying to have nema out view uart to a uart usb converter to be read by my robot and the connections from the base be read via the 3dr radio connected to USB OTG.

When I ssh into reach lsusb does find it.

Bus 001 Device 003: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)

But it can not be found in the /dev

When I look in the /sys/bus/usb/devices it is found as 1-1 with these contents.

I can not seem to figure out how to get reach to mount the device in /dev so I can use it to get corrections. Has anyone seen this before?

Please run the following and post its output:
dmesg | grep ftdi

It returned nothing. Sorry for the delay I was at a conference.

Could you please check that OTG adapter is not damaged, that FTDI device is working with a computer and that enough power is supplied to Reach.

Tried multiple adapters, tried multiple radios, same result. The OS knows it is there and even that it is an FTDI device but it will not link it to /dev/. I have also re flashed it and tried it on another Reach and the result is the same.

@sonyccd do you have an adapter with different chip? Like CP210x.

Could you elaborate more on what you mean?

USB-to-UART adapters are based on a variety of chips, the most common ones are from FTDI (FT232x) and from Silabs (CP210x). These companies as well as the others produce multiple versions of these chips. It may be worth trying another one.

I am not using an adapter it is plugging into the USB port of the 3DR radio. The radio has a build in FTDI chip. I have also tried using a FTDI adapter and that does not work. If I plug in an Arduino board that does work and I have been using it to forward UART for the moment.

Okay, does the radio connected over USB work with a computer?

Yes, tried on a Linux, Mac, and PC.

Confirmed. Seems like there has been an update of the ftdi driver package and it does not correspond properly to the kernel version. We will see what we can do about it and thanks for bringing up this issue.

Your welcome. Looking forward to an update.

Any update on this?

Working on it. If you don’t want to wait you could use a USB-to-UART adapter based on CP210x connected to the UART port on the radio, they work fine.

Sorry for the delay.

Temporary fix can be found here.
