Longcheer SU9800 does not work in linux, it seems there is something wrong when usb_modeswitch.
I have also test SU9800 in windows using usb-sniffer, it shows the vendorid and productid both is 1c9e:9800 for SU9800 either before switched or after switched.

although usb_modeswitch report: switch most likely succeeded, but modem-manager still begin to run. unfortunately, modem-manager sometimes open ttyUSB2, which is not normal because ttyUSB1 is right the modem. sometimes modem-manager may open ttyUSB1 and the connection can be established, but NetworkManager fail to get right DNS.

i think maybe it is because the switch has failed. the message content is the best doubt. so i try to get it through usb-sniffer in windows, but at last i failed,i just can't find proper message content. the info i get is as follows:

Please try this config file content:

Code: Select all

DefaultVendor= 0x1c9e
DefaultProduct=0x9800

TargetClass=0xff

MessageContent="55534243123456780000000000000606f50402527000000000000000000000"

CheckSuccess=20

Add a line for your device to
/lib/udev/rules.d/40-usb_modeswitch.rules

Have a look, it's quite easy.

I have missed the fine differences between the MessageContent you were using at first and the one in the existing config file ...

Please try again with your original MessageContent in your new config file:

Code: Select all

DefaultVendor= 0x1c9e

haha, i am glad to tell the switch has been fully successful .Can not thank you too much.maybe next time 1c9e:9800 can put into the package.

Post by **Josh** » 30 Jun 2011, 20:09

Yes, of course I will add the new device to the next data package release.

Great to hear it's really working!

dear josh:
i have another problem now, usb_modeswitch seems not work when the computer is powered on. I must re-plug in the usb modem. I have no idea about that.
can you give me some suggestion?

bestwishes

Post by **Josh** » 01 Jul 2011, 13:42

Your program version is a little dated (1.1.4). There are some specific improvements in the boot behaviour since version 1.1.6.

If you are not able to install a newer distribution package, you can always use the source package from this site. It's easy to install.

i have success,haha
