CONCLUSION (from my point of view and for my own case)
Problem is: reset or 'brown out state' of the modem
Caused by: USB power ripple/spikes when modem transmits a lot of data, or at high power (other possible reason: a USB connector malfunction like tremble, crack, dirt etc.)
H/W Solution by the user: contact an electronics technician to add capacitors externally (on a patched cable) 'filtering' the ripple spikes (first check and clean the USB connectors)
H/W Solution by the PC manufacturer: Do better design on the USB port to supply a 'good & steady' power for new advanced USB peripherals (as USB mobile broadband modems)
H/W Solution by Huawei: Add decoupling capacitors or split the power lines of the CPU, USB I/O and GSM/3G circuits to prevent resets and brown outs at difficult (for the circuit) situations.
S/W Solution at firmware: Sorry NOT available, ... or possibly a new firmware could 'amplitude modulate' the RF-TX signal to smooth the rise and fall of the RF PWR OUT at every data burst (true artificial intelligence), or change the threshold of the reset and brown out detect circuits to lower levels which may degrade the total performance of the circuit.
S/W Solution at driver: Sorry NOT good, ... or a new s/w driver could see the disconnects and try to reconnect and if not succeed would restart the computer, etc. I am not joking.
ale gdzie tu ... zewnętrzne kondensatory założyć ? i Jak LOOOL ...
Problem nie do rozwiązania software'owo :s
