Hi everyone,
I am trying to integrate EC200A-EU, on a custom arm am355x based Linux board. I have complied and installed the necessary option and usb_wwan drivers on the board. However, I keep receiving the following error messages in the dmesg logs:
[ 961.685448] usb 1-1.1: new high-speed USB device number 87 using musb-hdrc
[ 961.817167] usb 1-1.1: New USB device found, idVendor=2c7c, idProduct=6005, bcdDevice= 3.18
[ 961.835645] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 961.860504] usb 1-1.1: Product: Android
[ 961.864560] usb 1-1.1: Manufacturer: Android
[ 961.885654] usb 1-1.1: SerialNumber: 0000
[ 961.895131] usb 1-1.1: can’t set config #1, error -71
[ 961.907110] usb 1-1.1: USB disconnect, device number 87
lsusb does not indicate any newly added device. I guess the error message “can’t set config #1, error -71” indicates that the board is not able to supply sufficient power to the modem and hence the modem is not suitable for our board.
Your kind insight in this matter will be highly appreciated.
Thanks & Regards,
