Hi
I have problem with installation RM505Q-AE into my Linux device. I don’t understand why it is not listed with command lsusb. My goal is to integrate it with modem manager. Here i have some logs:

Dear Customer,

As described
2c:00.0 Unassigned class [ff00]: Qualcomm Device 0306
Please check whether you have set the RM505Q to pcie mode.

If the modem works in PCIe EP mode, please compile the pcie_mhi but not the qmi_wwan_q.

The gcc on Ubuntu 22.04 is over 11 and it is high so you failed to compile the qmi_wwan_q.

error: assignment of read-only location ‘<em>dev->net->dev_addr’
1893 | dev->net->dev_addr[0] |= 0x02; /</em> set local assignment bit */
| ^~

We could use memcpy instead of the operators.
