Looking for target devices
No target device found
Looking for default devices
No default device found. Is it connected? Bye
You have to edit /etc/usb_modeswitch.conf and add your device as target device. You may have to comment other devices and add the following:
##################
DefaultVendor= 0x12d1;
DefaultProduct= 0x1411
# choose one of these:
;DetachStorageOnly=1
HuaweiMode=1
###################
If it still does not find, use lsusb command to identify your device specification. Read the comments in the beginning of /etc/usb_modeswitch.conf file.
I am using Fedora 10. I used the above modification to the usb_modeswitch.conf, but I still get the message - no device found. lsusb shows the device ok. dmesg also shows the device and gives the following messaage:
