<div dir="ltr">Hi dear developers,<div><br></div><div>I want to ask you about the minimal supported version of Quectel by qmi_wwan driver.</div><div>I have following case:</div><div>- Ubuntu 18.04.3 (kernel 5.0)</div><div>- Inserted the module to the machine and have following log (1st one is Sierra, 2nd and 3d are Quectel modules):<br>lsusb -t<br>/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 10000M<br>/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M<br> |__ Port 14: Dev 85, If 0, Class=Hub, Driver=hub/4p, 480M<br> |__ Port 1: Dev 86, If 0, Class=Human Interface Device, Driver=usbhid, 12M<br> |__ Port 2: Dev 89, If 0, Class=Vendor Specific Class, Driver=qcserial, 480M<br> |__ Port 2: Dev 89, If 2, Class=Vendor Specific Class, Driver=qcserial, 480M<br> |__ Port 2: Dev 89, If 3, Class=Vendor Specific Class, Driver=qcserial, 480M<br> |__ Port 2: Dev 89, If 8, Class=Vendor Specific Class, Driver=qmi_wwan, 480M<br> |__ Port 3: Dev 88, If 0, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 3: Dev 88, If 5, Class=CDC Data, Driver=cdc_mbim, 480M<br> |__ Port 3: Dev 88, If 3, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 3: Dev 88, If 1, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 3: Dev 88, If 4, Class=Communications, Driver=cdc_mbim, 480M<br> |__ Port 3: Dev 88, If 2, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 4: Dev 87, If 4, Class=Communications, Driver=cdc_mbim, 480M<br> |__ Port 4: Dev 87, If 2, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 4: Dev 87, If 0, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 4: Dev 87, If 5, Class=CDC Data, Driver=cdc_mbim, 480M<br> |__ Port 4: Dev 87, If 3, Class=Vendor Specific Class, Driver=, 480M<br> |__ Port 4: Dev 87, If 1, Class=Vendor Specific Class, Driver=, 480M<br></div><div><div><br></div><div>mbimcli and qmicli don`t work with Quectel right now.</div><div><br></div><div>I found this thread: <a href="https://forums.quectel.com/t/em12-g-documentation-and-walktrough/3427/3">https://forums.quectel.com/t/em12-g-documentation-and-walktrough/3427/3</a></div><div>It seems that I need to update
QMI_WWAN and some other files but in addition I checked <a href="https://github.com/torvalds/linux/blame/master/drivers/net/usb/qmi_wwan.c">https://github.com/torvalds/linux/blame/master/drivers/net/usb/qmi_wwan.c</a> and it seems like in kernel version 5.13+ Quectel should work "out-of-the-box".</div><div><br></div><div>So my questions are:</div><div>- Did I do something wrong? Or kernel 5.0 is too old for my Quectel em12-g?<br>- Should Quectel em12-g work
"out-of-the-box" with kernel
5.13?</div><div>- Any corner cases with Quectel? Any guides? :)</div><div><br></div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">With best regards,<div>Alexander</div></div></div></div></div>
