Like most HSUPA USB sticks, MF190 double as a mass storage device. Windows driver and tools can be located and installed from here. After which, it will switch to modem mode. In Ubuntu, this process is done automatically (via usb_modeswitch and udev).

However, MF190 is not recognized. Is an extremely useful resource for getting a new and unrecognized device to work with usb_modeswitch. I used UsbSnoop to eavesdrop on the traffic going in and out of the device. Although it is warned that the tool should never be used on Windows Vista or above, I got it to work without much trouble in Windows 7. Getting the log using UsbSnoop is the first part of the story. The remaining is mostly guesswork, which isn’t too bad at all. The gem is at when URB 13 going down: [636735 ms] >>> URB 13 going down >>> -- URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER: PipeHandle = 87af955c [endpoint 0x00000081] TransferFlags = 00000002 (USBD_TRANSFER_DIRECTION_OUT, USBD_SHORT_TRANSFER_OK) TransferBufferLength = 00000200 TransferBuffer = 876a4b5c TransferBufferMDL = 0000000: 55 53 42 43 08 d0 8c 87 24 00 00 00 80 00 0010: 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 This message is sent when MF190 switches it’s state from the default mass storage mode to modem mode.

Using that, compose a conf file with the following content and save it as celcom_mf190.conf: ### celcom_mf190.conf ###################################################### ### ZTE MF190 DefaultVendor= 0x19d2 DefaultProduct=0x0103 TargetVendor= 0x19d2 TargetProduct= 0x0031 MessageContent=' d0' NeedResponse=1 CheckSuccess=20 Now, feed it to usb_modeswitch: $ sudo usb_modeswitch -c celcom_mf190.conf Among the more interesting output are: [ Truncated ] Using endpoints 0x01 (out) and 0x81 (in) Inquiring device details; driver will be detached.

[ Truncated ] Found correct target device Mode switch succeeded. Once mode switching is successful, right click on the network manager applet and select ‘Edit Connections’. Under ‘Mobile Broadband’, select ‘Add’ and the device should be available for use to creating a new connection.

The rest should be obvious. I am still getting my head around some of the issues such as how udev and usb_modeswitch work together. However, the immediate goal is to get this config into the upstream.

Snag a job manager log in. The one problem though is that it seems ZTE MF112 shares the same product id as MF190. But that’s different story altogether.
