A distinct possibility is that the modem needs to be reset somehow in order for the new firmware to take effect. If that reset were failing, it could account for what you see.
I've tried to reset all endpoints (0,5 and 7) and rescan the usb bus once the firmware is uploaded and before sending the first control message. But it doesn't solve the problem : I still get the USB control message timeouts.
Could it be possible that the firmware is buggy and that it doesn't understand the fixes included in the later kernels ? (It is working with kernels < 2.4.21-pre4 ).
