What happen to E220?
This problem had been occured before, and the solution is re-plug and restart, this time I want to keep machine in this state, and try to figure out the root cause.

I think the problem is in libusb's function usb_control_msg(),
it imply usb driver borken?

If there are any suggestion to solve this , please help me, thanks a lot.

Your device is still in modem state, no point in trying it to switch.

It might be a hardware related problem, which is outside my range of knowledge.
The only recommendation I have left to give is to use the "option" driver instead of "generic serial" - if it is available in your kernel version.

Sorry, is this use Huawei offical driver to instrad of usb serial? (forgive my ignorance):oops:

So in this crash state, it is hard to do anything to switch, the easy way is to replug and restart. Thanks~

The "option" driver is a serial driver that is optimized for wireless modems. Kernel developers lately are strongly suggesting to avoid usbserial - the generic driver - for these devices.

If your device is working - at least for a while - with usbserial, then it will work with the "option" driver too. Probably even without crashing ...
