Is there any news about this modem? Has anyone heard anything? I need this too...

Have you tried the command before that one in the log, i.e.:

[20476 ms] >>> URB 729 going down >>>
-- URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER:
PipeHandle = 818fadf4 [endpoint 0x00000005]
TransferFlags = 00000000 (USBD_TRANSFER_DIRECTION_OUT, ~USBD_SHORT_TRANSFER_OK)
TransferBufferLength ...

Not really. What I'm doing right now is when the device shows up, as Vendor=0x0408 / ProdID=0x1000, I send

usb_modeswitch -v 0x0408 -p 0x1000 -m 0x05 -M 55534243153311110000000000000600000000000000000000000000000000 -n 1 -r 0x84

Then I reboot my machine (a router). When it's booted the modem ...

That log looks terribly short... For comparison, my log from the ZTE MF-628 was 1 Mb, having 18000 lines.

So I think you only got the top of the log there (since you have the configuration stuff in it), and the switch command us usually at the very end.

Try to get a new log.

However, you've ...

Ok, I've tried out the Novatel MC990D and managed to make it switch.

It's a bit messy though, I had to patch usb_modeswitch so I could set which interface to use, since the default (0) didn't work (i had to use 5).

My patch is pretty simple, it adds a parameter "interface" (or "-i"), but since ...

Ok, I managed to get the MF628+ to switch, using this:

usb_modeswitch -v 0x19d2 -p 0x2000 -m 1 -M "5553424308403c862000000080000c85010101180101010101000000000000"

It goes from 0x19d2/0x2000 to 0x19d2/0x0031

I'm using a a branded modem from the operator "Telia" in Sweden.

I tried it as well, with a MF628+ (Telia Sweden branded), didn't work. I tried a set of other codes as well (the MF622 and MF620).

When I have time I'm going to sniff it myself, but it'll have to wait a week ot two.

If anyone else feels like sniffing it, post the log here and I'll see what I can ...

Have you tried HSOConnect? It's a program for linux that helps you conect using the hso drivers:

If that doesn't work, try this usb_modeswitch command:

usb_modeswitch -v 0x0af0 -p 0x6711 -m 0x05 -M ...

I updated my modem with a new firmware from the manufacturer, and now I can't send AT commands any more! I can in my laptop which I have kernel 2.6.17 in, but not in my router which uses 2.4.25 :(

I've patched up the usbserial to 2.4.36 version, but it still doesn't work. Does anyone have any ideas ...

Do you have some sort of SCSI command reference? Is it downloadable from somewhere?

I'm using both kernel 2.4.25 and 2.6.14, with just about the same modifications to the modules (in 2.4 it's <kernel>/drivers/usb/serial/usbserial.c, and in 2.6 I'm using <kernel>/drivers/usb/serial/airprime.c)

I just add the card id's to the usb_device_id lists (generic_device_ids in usbserial.c or ...

Ok, I've found anohter modem to play with, this one is used mainly in Taiwan so I can't find any sites in english :( Translated pages are, like, crazy ;)

It has the codes Vendor=0x0408 ProdID=0x1000 before switching, and when looking in windows it seems it switches to Vendor=0x0408 ProdID=0xEA02 ...

Yes, it needs to be switched, although it keeps the same codes after switching.

My scripts start by having no usb-storage or usbserial modules loaded, then run

usb_modeswitch -v 0x12d1 -p 0x1003 -H 1

Then wait 2 seconds, then load the usbserial module

insmod lib/modules/2.4.25-386/usbserial.o ...

Ok, I finally got around to test the HSO driver. I've tried on two cards, the "GT MAX HSUPA" and a firmware updated "GT MAX 7.2 READY".

The "GT MAX HSUPA" (Vendor=0af0 ProdID=7011) works fine. The option driver works no more, and usb_modeswitch works with the following settings:

usb_modeswitch -v ...

Yes, once the mode switch has occured, it stays in that state until the power is cut. You do not need to run usb_modeswitch again.
