Getting usb invalid interface number with EM060K-GL USB in ubuntu 22.04 and 20.10

justinLee · September 12, 2022, 10:14am

Dear,

we getting below with boot messages.
We can dial-up using quectel-CM and connect internet.

references :

Getting usb invalid interface number with EM060K-GL PCIE in Openwrt

we question :

how to fix invalid messages in the cold boot or reboot.
usb 1-3: config 1 has an invalid interface number: 8 but max is 6
usb 1-3: config 1 has an invalid interface number: 9 but max is 6
usb 1-3: config 1 has an invalid interface number: 9 but max is 6
usb 1-3: config 1 has an invalid interface number: 12 but max is 6
usb 1-3: config 1 has no interface number 4
usb 1-3: config 1 has no interface number 5
usb 1-3: config 1 has no interface number 6
Or is there documentation to prove that it does not affect function?
Is this message related to the FW of EM060K-GL?
(Because RM500Q, EM06, EG25, EC25, EM05…etc don’t have this message)

Dear Justin,

Could you show the result of

cat /sys/kernel/debug/usb/devices

and

lsusb -t

it seems like warnings because you didn’t install the tty serail driver.

justinLee · September 13, 2022, 1:54am

Dear Bean.Wang-Q :

thank for you reply.

“it seems like warnings because you didn’t install the tty serail driver.”
=> you mean “usbserial” driver ??

What I mean:

the option driver show match the usb interface.

justinLee · September 13, 2022, 7:29am

Dear Bean.Wang-Q :
I know insmod “option.ko” driver.

AT command is work. (“option” may only affect tty serial)
But, I want to know “how to fix invalid messages in the cold boot or reboot.”

my question :
I have update driver (usb_wwan, qcserial, option, qmi_wwan_q) to kernel.
But boot or reboot still have “invalid” message.

I thought so it was “If” not sorting!!!
ex: EM060K-GL => 0,1,2,3,8,9,12
I think => 0,1,2,3,4,5,6
Below is EM06-E message:
EM06-E

Bean.Wang-Q · September 14, 2022, 1:53am

yes. It should be in order.
But till now, it is like this.
Maybe it will be fixed in next version.

justinLee · September 14, 2022, 2:12am

OK~, I see.
FW will be fixed in next version.
Is there plan time?
So, “invalid message” doesn’t affect function?
How do explain it to our customers?

Thanks.

Bean.Wang-Q · September 14, 2022, 12:34pm

The interface like 4\5\6\7 might be used for other purpose, such as UAC and adb.

Yes it’s really a very bad experience for customers. I will write letters to the related software engineers and software project manager to fix it.

If I have any feedback I will inform you.

Bean.Wang-Q · September 14, 2022, 12:35pm

yes. It is warnnings and don’t affect the funtions.

justinLee · September 15, 2022, 1:36am

thanks for your help.
If you get any response, please inform me.

Thanks.

Bean.Wang-Q · September 16, 2022, 1:00am

Hi Justin,

Could you tell me which version of the firmware do you use?

justinLee · September 16, 2022, 1:59am

Dear Bean.Wang-Q :
I has no EM060K-GL AT command manual.
Could you provide me?
below message , reference RM500Q’s AT manual
FW_version

Thanks.

Bean.Wang-Q · September 19, 2022, 3:12am

Sorry Till now there is no AT command manual for EM060K.
You can use the manual for RM500Q.

RD don’t think it need be fixed. It is just warnnings.

justinLee · September 19, 2022, 3:28am

Dear Bean.Wang-Q :

OK, 
I know, but you(Quectel) could provide any documentation,
explain it is "No plan to fix".
let us provide to customers.
Can't just let us say "Quectel no plan to fix it".

Thanks.

Bean.Wang-Q · September 19, 2022, 3:35am

I cannot provide any document on the forums.
You can email to me: bean.wang@quectel.com.

justinLee · September 19, 2022, 3:46am

Dear Bean.Wang-Q :

OK, thanks.
has sent mail.

Thanks.
