Huawei E3372h-607 can't mode switch (Centos 6.10)

Post by Chris Maltby » 16 Sep 2018, 14:51

I'm totally unable to get the usb_modeswitch command (both distro and latest) to switch my E3372h-607 (Optus) out of storage mode. I'm using CentOS 6.

The command finds the device but none of a variety of options tried results in a change despite appearing to work:

Code: Select all

# usb_modeswitch -V 12d1 -v 12d1 -p 1f01 -P14dc -J -W
Found devices in default mode (1)
Access device 010 on bus 002
Get the current device configuration ...
Current configuration number is 1
Use interface number 0
 with class 8
Use endpoints 0x01 (out) and 0x81 (in)

USB description data (for identification)
Manufacturer: HUAWEI_MOBILE
     Product: HUAWEI_MOBILE
  Serial No.: 0123456789ABCDEF
Using standard Huawei switching message
Looking for active drivers ...
Set up interface 0
Use endpoint 0x01 for message sending ...
Trying to send message 1 to endpoint 0x01 ...
 OK, message successfully sent
Read the response to message 1 (CSW) ...
 Response successfully read (13 bytes), status 0
Reset response endpoint 0x81
Reset message endpoint 0x01
-> Run lsusb to note any changes. Bye!

I extracted the linux drivers from the virtual CD and installed enough stuff to get their "mbbservice" binary to run. That immediately switched the device to 12d1:14dc and the kernel recognised it as a cdc_ether device.
