First:

I know nothing about the ZTE MF622 USB 3G Modem. I am evaluating the purchase of one of this modems and, as a Linux only user (inlcuding my internet tablets), I am validating if the device works with Linux, specially with the NIT N810.

Once said that. I found this link that states that removing the usb_storage module then, the device should switch itself to a modem mode and hence work correctly as a modem.

This is based on the fact that the ZTE is not an storage device.

Could some of you verify if this is also valid on the Internet Tablet (OS2008) when a ZTE MF622 is attached to its USB port. ?

I hope we can make the 3g Modem work as it will give even more life and usefulness to the NIT.

Comments are welcome.

Kind regards.

I plugged in my ZTE HSDPA MF622 3G modem (trough a powered USB HUB) and this is an output of dmesg:

Is there any chance to put this modem working to access internet?
