I have USB CDMA Modem with "flip flop" mode (USB CDROM and USB CDMA Modem).
Here the method I use to connect:
1. Plug device
2. run eject /dev/srx (x is number of my USB CDROM usually /dev/sr1)
3. run sudo modprobe usbserial vendor=<my USB CDMA vendorid> product=<my USB CDMA productid>
4. run sudo wvdial or sudo pon
It works, but sometimes (or often) wvdial or pon disconnected suddenly, then I can't redial because my modem is no longer exist. To solve this problem, I must reboot my computer or unplug the device, plug it again and run the method that was mentioned above.
Question:
Is there any command to "re-detect" my device instead of reboot or "re-plug", may be by restarting kernel module that control USB device?
Any suggestions will be appreciated
