Hi,

I have now managed to get my MC 7455 to work very well, but I have some errors logged:

usb 1-1.3: config 1 has an invalid interface number: 8 but max is 4
usb 1-1.3: config 1 has an invalid interface number: 10 but max is 4
usb 1-1.3: config 1 has no interface number 1
usb 1-1.3: config 1 has no interface number 4
usb 1-1.3: New USB device found, idVendor=1199, idProduct=9071, bcdDevice= 0.06
usb 1-1.3: Product: Sierra Wireless MC7455 Qualcomm® Snapdragon(tm) X7 LTE-A
qcserial 1-1.3:1.0: Qualcomm USB modem converter detected
qcserial 1-1.3:1.2: Qualcomm USB modem converter detected
qcserial 1-1.3:1.3: Qualcomm USB modem converter detected
qmi_wwan 1-1.3:1.8: cdc-wdm0: USB WDM device
qmi_wwan 1-1.3:1.10: cdc-wdm1: USB WDM device

It complains over interface number 8 and 10, but it still use them.

Do you have any idea about how to get rid of this?

This is the interface config (default, not changed by me):

at!usbcomp?
Config Index: 1
Config Type:  1 (Generic)
Interface bitmask: 0000050D (diag,nmea,modem,rmnet0,rmnet1)



Best regards,

Peter
