Hello,
Thank you for the latest release.
Sorry to inform you that the previous release didn't bring
the desired relief.
There's no gsmmodem link created on plugging in. Log below.
Looking at the src there's a comment:
# Unfortunately, there are devices with more than one interrupt
# port. We have to check all ports and assume that the lowest
# number denotes the working port
As noted above in the bugreport history, this condition is not
a sufficient one to fix the link-to-wrong-INT-device problem
for devices with multiple interrupts.
There's the condition to be met as described in the early post,
the IDs must match. For us, that's the working fix ever since.
Fully working, with always functional gsmmodem links:
usb-modeswitch 1.1.2-3 with the above patch.
Partially working, with occasionally dysfunctional gsmmodem
links: usb-modeswitch 1.1.3-1, implementation detail missing.
Not working yet: usb-modeswitch 1.1.4-1, insufficient condition.
