dmesg shows nothing,too

Hi,
no idea what I'm doing wrong here:
cat /sys/bus/usb/devices/1-3/product
HP hs3110 HSPA+ Mobile Broadband Device
ls /sys/bus/usb/devices/ |grep 1-3
1-3
1-3:2.0
1-3:2.1
1-3:2.2
echo -n "1-3:2.0" > /sys/bus/usb/drivers/cdc_mbim/bind
bash: echo: write error: No such device
You're not doing anything wrong. That error is consistent with the
probing failure. Do you have dynamic debugging enabled? If so, then
mount debugfs, do
echo module cdc_ncm +fp >/sys/kernel/debug/dynamic_debug/control
and then repeat the manual bind. Hoping this will produce a more
specific debug message.
