Hi,
I would like to pass Pass-through some 3G modem to my qemu VM, but since an USB 3G modem use to expand to multiple sub-USB device after init, it’s a bit more complicate than a more standard device.
Since I would like to pass-through a couple of them to my VM, I’m not sure about the way to process.
I would like to pass-through, an USB HUB top my VM, but in this case the modem never appears inside the VM.
Maybe I should blacklist some kernel module to avoid initialization from the main host.
Adding a new PCI USB controller in not an option I’m running out of slot.
Any suggestion ?
first try:
addint a file in /etc/udev/rules.d
containing:
SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1436", ATTR{authorized}="0"
Then after reboot, after plugin in 2 KEY:
big:~ $ lsusb
...
Bus 001 Device 013: ID 12d1:1436 Huawei Technologies Co., Ltd. Broadband stick
Bus 001 Device 014: ID 12d1:1436 Huawei Technologies Co., Ltd. Broadband stick
And the main linux did not try to enable the keys.
a good start.
