FS#2319 - usbmode bug which is fixed in usb-modeswitch...

I wrote a bug report but then the bug report said wrong token and I lost the report... :(

Now again but shorter version. The usb-modeswitch (which seems to be an openwrt project, a rewrite of original usb_modeswitch ) needs to set some devices to config 0 before switching to config 3.

BTW this is fixed in usb-modeswitch... Here is the link to discussion about this:

Some devices need to be set to config 0 first to be able to switch to config 3. Otherwise they hang...

Here a working example:

root@OpenWrt:~# echo 0 > /sys/bus/usb/devices/1-2/bConfigurationValue
root@OpenWrt:~# echo 3 > /sys/bus/usb/devices/1-2/bConfigurationValue
root@OpenWrt:~# umbim -d /dev/cdc-wdm0 caps

devicetype: 0001 - embedded
cellularclass: 0001
voiceclass: 0001 - no-voice
simclass: 0002
dataclass: 8000003F
smscaps: 0003
controlcaps: 0001
maxsessions: 0003
deviceid: 867377023108313
firmwareinfo: 11.617.06.00.00
hardwareinfo: RM1ME909ASM


A non-working example (after reboot):

root@OpenWrt:~# echo 3 > /sys/bus/usb/devices/1-2/bConfigurationValue
root@OpenWrt:~# umbim -d /dev/cdc-wdm0 caps
ERROR: mbim message timeout

At least one other person in OpenWRT bug tracker confirms this:

Although he has another problem with looping messages (probably unrelated to this bug)
