My usb GMS/EDG/3G modem is SpeedUp SU-8200U

After sniffing in windows, I got many messagecontent, and after i compare it with the device list, it has similarity with Alcatel OT X020

The first snoop configuration seems to bee working with a limited speed in Ubuntu 10.04, with the SYSFS command

but it's not working in PcLinuxOs 2010.12 (in 2010.12 the SYSFS command is changed to ATTRS) [the first and the second]


The device reference settings for Alcatel is working for my modem in 20.12 live cd mode (the modem is detected in the OtherDevice Category, and can be used, but without limited speed)

when i installed 2010.12 in my harddisk and booted from it, the modem is detected, but it's listed in Scanner category and cannot be used

my question is
what should i do to :
1. Make my modem detected under the right category, and can be used to connect to the internet
2. If connected, how can I make it run with full speed?

I'm not sure if I understand: the default setting from Alcatel is working, with no speed limitation - that's full speed, right?

Also, I don't get what you mean by "speed" - the USB port speed or the network speed ?

yup. the alcatel's setting can be used with full speed (modem speed, not the port speed)

the only problem i'm having right now is the modem is not detected under the right category, so it cannot be used
it is located under scanner
is there any solution that can move it to the modem category, so it can be used?

I don't know your distribution, but usb_modeswitch (the source package) has proven to work on many different setups. It needs udev, libusb and tcl, and that's about it. So why not install the latest version from source ?

The point is that it will try to load and bind the right modem driver after the device was switched; the system should see that it is a communication device afterwards.

Oh, and check if you have the "option" driver available; also, in some cases the "cdc_acm" driver is used.
You can test with a simple "modprobe -v option" (as root or with sudo).

the options device sometimes appear, but under it, it's usually detected as USB MMC Disk (cannot be used either)

my distro is pclinuxos, based on mandriva.

ok i'll try your suggestion and try to compile from source, hopefully it'll work
