I’m observing error when trying to use RM510Q-GL module on Atom x6413E system. Kernel fails to set USB configuration when module is inserted in USB 3.0 enabled B-Key slot.
[ 8546.497670] usb 2-4: new SuperSpeed Plus Gen 2x1 USB device number 2 using xhci_hcd

[ 8546.524098] usb 2-4: can't set config #1, error -32
Similar issue is observed with Windows 10 and on 2 different devices, which excludes HW failure or OS issue.
Same RM510Q-GL works fine in another (older Xeon-D) system (also USB 3.0 enabled slot) so this is not faulty module issue.
Further debugging shows that XHCI driver reports Stall after SET_CONFIGURATION:

Any idea what might be wrong here?
Thanks in advance!
This situation it is mostly caused by the USB host. Generally speaking, if you see an error like can’t set config #1, error -32, it is caused due to the hardware error, or the driver of the USB host controller.
You can try to use the USB port, or even try the USB2.0 port, or use another the USB cable.
You can also try
echo 1 > /sys/bus/usb/devices/2-4/bConfigurationValue
to activate the configuration.
Please note that in the same slot Sierra Wireless em7455 works without any issues as ISB 3.0 device, so I will not rush into conclusion that this is host issue. It is unlikely driver issue as both windows and latest mainline linux doesn’t work.
Setting configuration trough sysfs doesn’t work, same stall observed in xhci debugs after SET_CONFIGURATION control message.
it is weird issue, as this is not 1st usb control transfer which happens. Card nicely replies to other control transfers, only SET_CONFIGURATION is either not received by the card or card refuses to reply for some reason.
If so you can use usbmon to capture the log of the usb bus.
Here is full usbmon for that card:

Is there anything else I can do to help resolving this issue?
Thanks!
From the usb log
We can see that it’s noproblem to
Get_Descriptor
Get_Configuration
but failed in Set_Configuration
I can’t find the reason why it is.
Yes, so should I give up and declare that this Quectel module is not compatible with Intel Elkhart Lake or there is still hope that this can be fixed?
Hi Dmarion & Bean.Wang
Are you guys able to resolve this issue ?
I am having the same issue on an Intel NUC 12 pro.
