Blacklist the default VID:PID for the Linux USB Serial Gadget in ACM
mode:
{LINUX}/drivers/usb/gadget/legacy/serial.c
#define GS_VENDOR_ID 0x0525 /* NetChip */
#define GS_CDC_PRODUCT_ID 0xa4a7 /* ... as CDC-ACM */
This should never be reused for real products by hardware
manufacturers, but anyway...
Patch actually ported from downstream Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1105352
These CDC ACM class devices are docking stations for Sigma Sport bike
computers. As they are sensitive to single byte commands, ModemManager
probing mechanism actually caused training data on attached bike
computer to be zeroed.

This patch adds another Infineon flashloader device 0x8087/0x0801
to the blacklist

ModemManager locks the proxmark3 when it is connected. As it is not a modem,
ModemManager shouldn't be talking to it.
At present, the recommended action in the proxmark3 documentation is to
purge ModemManager to fix this issue.
Note that this vendor uses an unregistered USB device ID, so it is
instead matched by the manufacturer string.

MM probing appears to make 'visor' module die; and anyway
most of the devices driven by 'visor' are not phones, and
of the 3 that are phones they are so old (2002 - 2005 era)
that nobody is likely using them for dialup anymore.

A device like this shows up briefly while the Sierra EM7345 is booting:

E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
We do have a driver identifying this as an "Infineon Flashloader"
device. It is not a modem in any case, and should be ignored.

We make many USB virtual COM port devices, none of which are modems.
ModemManager's automatic attempts to access those devices can cause
problems.
That might change in the future, so we have left two potential
future product IDs off of the blacklist.
The Bus Pirate v4 presents itself as a CDC ACM device which
ModemManager attempts to configure. This results in a range
of confusing issues because it injects a bunch of AT commands
over whatever is going on at the time.
Firmware updates were failing at random points and avrdude
failed to work at all. Blacklisting it fixed my issues.
