Re: usb modem "Can't setup transfer"
Hans,
Thank you, that allows it to attach and the device nodes appear in /dev/
However I then can not seem to send any AT commands and get a response
via either cu -l /dev/ttyU1 or cu -l /dev/ttyU1.
Any further steps? Is there a way to virtually share this hardware with
you?

Hi,
The device is very special in that it uses an interrupt type of
endpoint for receiving the data.
Endpoint 1
bLength = 0x0007
bDescriptorType = 0x0005

bmAttributes = 0x0003
wMaxPacketSize = 0x003f

bRefresh = 0x

In umodem.c you might want to change the USB matching filter to accept
interrupt endpoints:
[UMODEM_BULK_RD] = {
.type = UE_BULK, // change this to UE_BULK_INTR
.endpoint = UE_ADDR_ANY,
.direction = UE_DIR_RX,
This change will break other modem drivers, but at least it will give
some clues if it works or not.

Hello,

When I plug this device into FreeBSD I get a ugen0 device.
So I tried hacking into the driver itself:

I read the Linux driver and it seems pretty similar, although it does
look like they have a ton more quirks and edge cases the handle. The
file in Linux I'm looking at is: linux/drivers/usb/class/cdc-acm.c (this
seems to make the most sense given the instructions given at
ftp://ftp.multitech.com/usb/usb-linux2.txt).
I tried turning on sysctl hw.usb.debug=10 however after doing so it
didn't seem to want to probe anymore.
Any ideas?
I can ship this modem to someone if they are interested and have a good
idea how to fix.
Hi,
Can you send the configuration descriptor dump:
usbconfig -d X.Y dump_device_desc dump_curr_config_desc
Maybe the modem fits into the U3G driver.

Hans,
Moving it to u3g on -current gives nearly same error:
