Dear Maintainer,

it looks like dmrconfig does not detect all radios, here a GD-77. The output of
dmrconfig -r -t says:

dmrconfig -r -t
Cannot find USB device 0483:df11
Cannot find USB device 15a2:0073
Cannot find USB device 28e9:018a
No radio detected.
Check your USB cable!

You see 3 different addresses for usb, and these are exactly those in /lib/udev/rules.d/60-dmrconfig.rules.

lsusb is telling me this:

lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 5986:0102 Acer, Inc Crystal Eye Webcam
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 003: ID 1fc9:0094 NXP Semiconductors OpenGD77 Transceiver
Bus 003 Device 002: ID 24ae:2010 Shenzhen Rapoo Technology Co., Ltd. Rapoo 2.4G Wireless Device
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So you see, my device is 1fc9:0094

Knowing this, I added this line in /lib/udev/rules.d/60-dmrconfig.rules:

# Radiodditty GD-77
SUBSYSTEM=="usb", ATTRS{idVendor}=="1fc9", ATTRS{idProduct}=="0049", MODE="666"

but got the same result.

Then I checked with strace, and discovered this interesting line:

fstat(3, {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0

As you see, it is looking for /sys/devices/virtual/tty/uevent, /sys/devices/virtual/uevent and /sys/devices/uevent, but does not find any, and of course it stops then.

I checked, but on debian none of these files exist.

Maybe youu might want to take a look at this?

Tnak you vvery much for any help.

Best regards

Hans
