A user may really need cdc-acm. > Your work around may cut somebody's connect to the web. By temporarily blacklist cdc_acm I mean, "disable cdc_acm during firmware update". As root user:echo "blacklist cdc_acm" >/etc/modprobe.d/cdc_acm-blacklist.conf rmmod cdc_acm # ignore ERROR: is not currently loaded ## if module is in use try to disconnect the devices associated. plug the usb cable and run Heimdall (normal user) at end remove the file /etc/modprobe.d/cdc_acm-blacklist.conf -- This solution works for all IDs and prevents also the ModemManager to probe of the device (there is no device ttyACM*).
