The modeswitch for MF691 (T-Mobile Rocket 2.0) (v=19d2, p=1201/1203) usually does not work during bootup on a raspberry, but does work on hot-plugin.
Since I am building a standalone system, it needs to work on bootup.
Log output for both a successful and unsuccessful modeswitch during bootup is here:
/* First, a succesful modeswitch during boot (happens rarely) */
/* Note: A hot-plugin always works */

Re: modeswitch not working on bootup for MF691
Hmm - usb_modeswitch does its job in both cases. The logical conclusion is that there are other factors involved, specifically the state of the system (kernel).
Instead of digging for the exact cause, you can try to tweak some parameters which influence usb_modeswitch's behaviour.
My first recommendation is to play around with the WaitBefore parameter. Copy the file
"/usr/share/usb_modeswitch/19d2:1201" to the folder "/etc/usb_modeswitch.d" and edit it; add the line
"WaitBefore=5" to make usb_modeswitch wait five seconds before even touching the modem.
My guess is that if you adapt that value (probably increasing it), you'll get the desired result.

Works now, thanks.
