I just got hold of a samsung 4g/lte modem, a usbstick which just came
out here in sweden. Putting it into my debian box, kernel 2.6.30, udev
recognizes it as a cd(with the driver) as expected. I blocked the
cd-recognition with a udev-rule and manually tried to load usbserial for
it, but no luck.

This is what dmesg gives me now:

[34484.588050] usb 4-1: new high speed USB device using ehci_hcd and
address 15
[34484.721548] usb 4-1: New USB device found, idVendor=04e8, idProduct=6876
[34484.721557] usb 4-1: New USB device strings: Mfr=1, Product=0,
SerialNumber=0
[34484.721564] usb 4-1: Manufacturer: SAMSUNG ELECTRONICS Co.Ltd.
[34484.721758] usb 4-1: configuration #1 chosen from 1 choice

Anyone got any hints on where to go next?

Best regards,
Eric

As the usb-modem is new, i suppose that the product-id is not in the kernel. therefore the stick is noch recognized.
you could - even if chances are rather small - try to modify the kernel-source to get the device directly recognized if there is a similar device, whose driver can be used.
or you could take a look here if you want to use usbserial: http://www.linuxjournal.com/article/6573
maybe that'll help. i have no experience with usbserial.


sorry,

Michael.
