Package: modemmanager
Version: 1.6.2-1
Severity: normal
Dear Maintainer,
I develop/use/sell USB TRNG (True Random Number Generator) device
which works as an USB CDC/ACM device.
The intention is that users can get the random bytes from /dev/ttyACM0
with no drivers installed. Unfortunately modemmanager interferes.
For its users, I recommend to have a following udev rule:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="234b", ATTRS{idProduct}=="0001",
ENV{ID_MM_DEVICE_IGNORE}="1"
And then, the device works fine.
Given the situation I distributed more than 200 devices, I think that
it makes sense to have the udev rule above in the modemmanager
package.
The hardware is by free hardware design and the firmware is free
software.
It is also possible to run the firmware on another board which is
cheap enough. Please have a look at:

So, I think there are more users of this device.
