Just FYI - no, bcma-hcd was not needed, /etc/init.d/gtm382 was enough for
lsusb to see modem:
#!/bin/sh /etc/rc.common
START=11
cd /sys/class/gpio
echo 4 > export
echo 5 > export
echo 7 > export
cd
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value
echo out > /sys/class/gpio/gpio7/direction
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value
echo out > /sys/class/gpio/gpio5/direction
echo 1 > /sys/class/gpio/gpio5/value

Hello,
I am using openwrt-19.07 branch, CONFIG_TARGET_brcm47xx, device is Option
Globesurfer III.
I have an older openwrt image from 2015 with kernel 3.3.8, where 3g modem is
seen by lsusb:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 04cc:1520 ST-Ericsson USB 2.0 Hub (Avocent KVM)
Bus 001 Device 003: ID 0af0:7601 Option Globetrotter MO40x 3G Modem (GTM
382)
With openwrt-19.07 branch lsusb does not see it:
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 04cc:1520 ST-Ericsson USB 2.0 Hub (Avocent KVM)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I suspect it is because older image has bcma-hcd.ko kernel module. I tried
to include
kmod-usb-bcma in openwrt-19.07, but when compiling I get:
WARNING: kmod-usb-bcma is not available in the kernel config - generating
empty package.
Why is it so? In package/kernel/linux/modules/usb.mk:
define KernelPackage/usb-ohci
TITLE:=Support for OHCI controllers
DEPENDS:= \
+TARGET_bcm53xx:kmod-usb-bcma \
+TARGET_brcm47xx:kmod-usb-bcma \
+TARGET_brcm47xx:kmod-usb-ssb
