The modem works using a 16.04.1 live USB stick, but not on the installed on-disk 16.04.2. Below is the lsusb -v in from the live-USB where the UMTS modem works, first the USB Hub usb2, then the Huawei device. The information from the running system where the modem does not show up is attached through apport. I also have access to dmesg on both systems, see further below for the successful case. I also tried to copy kernel and modules from the live-USB to the hadr disk, booted successfully, but still nothing in lsusb. I also tried a few times to use for i in /sys/bus/pci/drivers/[uoex]hci_hcd/*:*; do echo "${i##*/}" > "${i%/*}/unbind" echo "${i##*/}" > "${i%/*}/bind" done for resetting the bus, still the same. I would welcome some suggestions what to test, if there could be a firmware issue blocking the UMTS, if teh modem could be blacklisted (how do I check that ?) whether udev or systemd could be a problem, whether there could be a missing package in the HDD installation (which?!) or if UEFI in the boot chain ("sdhci: Secure Digital Host Controller Interface driver") could cause an issue. Or if it makes sense to manually run usb_modeswitch (how?) without the device even be in lsusb ?
